Did you like the performance of the EcoFlow Delta 2 power station!? Purchase the EcoFlow Delta 2 using the 5% OFF DISCOUNT CODE ( LGL23I6B ): us.ecoflow.com/?aff=216
I need this one. Originally I was going to buy bluetti eb3a and 70s, but now I think all I need to buy is the Delta 2 for $1K vs the other two bluetti for $800. Does this one buy make more sense?
Seems people getting different efficiency results for AC & DC. I'm trying to decide on this box but seeing 74% reported except what Jason reported. Anyone reported lower efficiency?
Awesome review Jason. Really great data and presentation! I agree with the tweaks you made to the rating system, that's super helpful to people shopping for units.
Great review, been considering this unit, used the promo code and ordered today with a bonus waterproof bag at no charge. Perfect for camping and hurricane back up to power the fridge.
They finally went LiFePO4!! I think now that they are at the 'standard' (at least for people in the know who are researching), their other value adds (fast charging, 1800W inverter, expansion, backwards compatibility) put them above the competition. They are back on my radar! Thanks for the review, Jason!
Excellent review; thanks for explaining the lack of independent charging for the extra battery at the 19:00 mark. An area for improvement for EcoFlow on an otherwise good product
Jason after consideration about how I use the delta 2. I have decided that for my purposes, the extra battery would be a waste of money. So I'm buying a second delta 2 instead. Basically we only spend time in two maybe three rooms in the house. Two of those rooms are side by side. The delta 2 can run everything in the kitchen except the range. Out the other one in the master bedroom. I can't do that with the extra battery. If I ever decide to get a transfer switch to run house. I'll be purchasing a larger unit with expandability. Oh and the two rooms next to each other are kitchen and den. The only we run in den are TV and a couple of lamps. What say you.
I think that will work well for what you have described. You can even have one charging while the other on is in use. I love how small and lightweight these are.
Another great review Jason! :) And it wasn't too long at all. A really well made and in depth video. Just what someone needs to see before buying a power station like this. Looking forward to more ecoflow products getting the LifePO4 makeover too.
Excellent, thorough review. While you said this was a long video I prefer this to a five minute cursory introduction to a $1,000 device. Earlier this year our power was out for almost 18 hours. No AC, no fans, no cooking. I looked at a Milwaukee battery powered fan and that was about $100. A Delta 2 seems like a bargain in comparison since I can run a fan, use a kettle and an induction cooktop. Coffee maker too.
Excellent job. You keep adding new angles in your reviews and I love it. I have been waiting for this unit for awhile. One disappointment is the 60V solar limit. Bluetti had a similar issue with the EB150, then they released the EB240 and raised the voltage a bit. EcoFlow should have made it something like 66V or 70V. In any case, small complaint for a nice unit.
Yeah, you have to have very specific panels to put them in a 3s config. Luckily it allows up to 15 amps input, a large improvement over the 10 amp limit of the EB120/EB150. So you could probably still get max power with a 2S config as well.
FYI: the idle power consumption for the DC output is actually about 3 watts or ~0,3% per hour. The SoC meter just doesn't register it so you could end up with an empty battery a couple of weeks while the Delta 2 is still indicating 100%. Same goes for low power solar charging. If you only input a couple of watts, the SoC stays the same. This has thrown me off the loop a couple of times until I figured it out. I suppose the current shunt isn't accurate enough to produce enough voltage drop at such low currents.
Eco Flow Delta 2 is going to sell all they make! Thank you for the review. I congratulate Eco Flow for getting a 9.5 out of 10 score. Finally, I want to say good for Eco Flow to refer to one of its features as an EPS (Emergency Power Source) and not UPS (Uninterruptable Power Source).
I like how they aren't claiming it to be a true uninterrupted power supply. You can see in my video it worked with the desktop just fine, but failed with the monitor. Some devices will work and some won't as it cuts over. Overall, very good performance for a portable unit.
I was disappointed to find that you cannot use the Ecoflow Wave air conditioner AND another battery but I don't think that's an issue for most people. Well you can but not through DC.
Great review thanks so much! About to purchase on Amazon with $250 discount & free waterproof case… this will reduce some anxiety once I receive it. World is getting crazy!
Very nice that's it has lifepo4! This is more than likely be my next solar generator purchase. These power stations are collectibles with so much utility lol
I really like that point about the extra batteries just being a way to expand capacity and nothing else. No way to charge or use outside of the main device. I had the idea that, on my Delta Pro, I could use the extra battery to bring outside and charge via solar during the day then bring it back inside to keep the main battery going at night but you can't do that. Shame cause, if you want to use the Delta 2 or Delta pro as your main station and keep it in a specific spot, it could be hard to bring out to wherever power is coming unless you get longer cords or have a setup already installed or something. At least with the Delta 2, it's a looooot easier to carry around, lol. Thanks for the video!
Just like everything else, power stations keep getting better and certainly more expensive. I like that it's lightweight!! I can pick it up and put it where I want it. That's a plus for me! Thank you for the review, Jason!
Looking through the spreed sheet I didn't see a column related to expandability via additional batteries. That for me would be very helpful as I can take head unit for camping and use expanded setup for more of home backup system if I can add enough batteries. Great videos.
Great video as always! I have a suggestion for a future tests. For solar applications it's crucial to have a good round-trip efficiency in addition to a good inverter and dc circuitry efficiency. Could you also measure the total input energy in kWh needed to charge a solar generator fully? Putting a power meter between the solar array and the MPPT controller input would help in sizing the array. And while you're at it, why not measure the input energy while charging from AC with the Kill a watt you use for inverter output efficiency tests?
There are 3 tubers I follow you included and on the other channel the computer turned off, the relay switch used on the Delta 2 was not fast enough to use as a UPS. Interestingly all 3 of you loaded up the videos today. Just FYI, I understand that if one also owns the Delta Max and you own the expansion battery you can use that battery on the Delta 2. Love your videos and great job on this one too. Keep up the good work.
Those videos came out at the same time since the product was launched that day. We are given a "video launch time" and the video can't come out before then :) Thanks for watching Shelley!
I'm very likely buying this power staton for charging my e-mountain bike for camping and hunting. The TWO reasons are: 1.) the LFP battery with greatly expanded cycle life over Li-ion stations. 2.) its companion battery expansion, ALSO with LFP battery technology. This expansion battery is mainly for home emergency use. I plan to charge this when camping/hunting with an Off Grid TREK solar blanket draped over my MAZDA CX-5 windshield and roof with the DELTA 2 locked inside the trunk while I'm away from camp. In the evening I'll simultaneously re-charge my E-MTB's 2 batteries in its patented single charge port.
This is SO useful. Just found your channel. OUTSTANDING review and comparisons to competing brands. Excellent spreadsheet. Liked and subbed! PLEASE can u compare AC200Max to the Delta Max?? :) :) TWO RIVALS so very similar in WH and price. :) :) (edited: i just realized the Delta Max is not LFP…aka 1/3 life…forget that) Thx Jason!
Hey Ronny! I'm sure EcoFlow will put out a Delta 2 Max (LFP version) sometime in the future. For now the Delta 2 is the only LFP version they offer. I have the AC200max and I will be doing a review video on it later on the channel :)
We just purchase this unit. We did have the cord for the solar panels included. Thank you for your detailed review. I am trying to learn how to get the best use from this power station before we actually need it. God bless you.
Hey Dr J' Very, very good information! Ecoflow is constantly updating their products and I appreciate your prompt dropping of these types of review videos. I think this is the combo I would like to use for our home backup system but the way my checking account is set-up 🤣😂
Excellent review! I will seriously consider getting one. As usual, I am extremely disappointed in the liar-label on capacity, but it otherwise appears to check all the boxes, including the 500W charge rate on solar.
I don't think they are lying on capacity - the battery cells are rated at 1024wh but there will always be losses with batteries as you pull power from them and convert it into AC power or step down the battery voltage from 48v to 12v. 20% losses are the average in the industry and this is a bit above that.
@@todd.parker That's a move that not many people have noticed or might not even care. They used to be real heavy, now they're lighter than all of them. Less battery, more voltage. I've definitely noticed the loss in conversion. I lose 60 watts an hour with my Bluetti. It's enough to make me reconsider keeping something running 24/7. I think the issue, if there is one, would be that this unit is less efficient than other Ecoflow products.
Thank you for the review. I’m an energy minimalist doing most cooking via 12v and charging with 200watts solar. My only concern is having repaired under warranty.
Ecoflow support has always been responsive both over the phone and email. They replaced my River Pro when it had issues. Give them a call and test it out. See what you think about their service.
Love the video this eco-flow is everything I wanted too bad I just purchased the blue Eddie Max 4 months ago but my next power station will be this eco-flow thank you again I can't wait for your next video
@@j-sonS in previous test videos he has plugged the power stations into a heater to test ups functionality. I haven't seen his video this morning, but as you can see from my testing, the UPS mode works just fine for sensitive electronics. My PC didn't turn off after testing it multiple times 🤷
@@Jasonoid This time Hobotech used a laptop with the battery removed as the test load, and it powered off during the switch. I guess his test unit may have a fault with its UPS relay. Glad to see your unit give better results!
@@j-sonS I think the differences can be chalked up to the different PCs and amps each used. Hobotech was using a really ancient laptop and Jason seemed to be using a more modern PC that maybe can handle longer power blips. Same with the amps - Jason's might just be better shielded?
It's also possible Hobotech had a earlier review model, Jason's seemed a bit better optimised with the car charging too. Maybe they watched Hobotech's review and tweaked a few things. Always going to be variations in units at this price too. Either way this is a great review video Jason thanks
I have the River Max and the River Pro with the extra battery, I will be adding this one to my collection in November, that is when I will have enough money saved for it . 😎😎
I have been using this one around the yard a bunch since it's so lightweight. For example I needed a bright LED work light out in the yard after dark. Instead of pulling out a 100 foot extension cable and running it from the house, I just plugged the light into this haha!
Thanks for your feedback. I love how you can change the charge speed on the app. Most power stations don't offer that feature. Charge anywhere from 200 watts up to 1200 watts!
Really enjoy your videos. I’m looking at buying a portable power station to power my Snomaster CL56D fridge/freezer. I will have it in my work truck and I am trying to figure out the best way to charge it while I’m driving. The fridge does allow you to have both AC and DC connected, but will default to AC power if connected. If I’m right I could use the portable power station to charge while driving while running the fridge off AC power on the pack. Once the truck is shut off the power pack will disconnect from charging and the fridge will switch to DC power in the power pack.
Awesome review Jason really well done. Looks like a great unit. Wish the UK price would come down a bit though, 1100 pounds here. Maybe they will try selling combo's for cheaper. Cheers
Hi all, So....I have a hack that I literally just thought of for people who can't afford another Delta Pro or extra battery BUT need additional power and own another ecoflow battery. I have called ecoflow and given them the idea as well and they confirmed that it will in fact work!! I then asked them why they don't tell everyone after I've told them and they said they would "escalate the idea" to their top tier and perhaps add it to their FAQs. So here's the idea: We've been told that you must have like systems in order to use them together. This is NOT actually true. If your Delta Pro is low on power (or any other ecoflow system you have) you can simply plug its charging cable (in the rear) into the front of the secondary system. In other words you're using the second system as a wall outlet of sorts. This works especially well in the evening when the sun is down and there is no more backup energy. What do you do when the sun is up?...even better...plus the second system from the rear into the front of the Delta Pro. This allows the sun to charge them BOTH regardless of the differences of their capacities or sizes!!! The only word of caution they gave me after saying what a great idea this was, was to say don't forget to lower the charging speed on the Delta Pro once it's plugged into the front of the second system. Guys this means you can use anything from a River and up to charge your Delta Pro OR any other ecoflow system. If this works for you please like my comment and say "Thanks T!!" just so I'll know at least I was able to communicate something helpful to the solar community-especially since these systems are sooooo expensive!!
I wouldn't say they were different results, he just tested a different device. I saw that he tested a laptop without a battery. I like to give realistic tests in my videos so I'm not sure how many people use laptops without batteries on a daily basis. Under some circumstances the EPS mode with the 30ms cuttover won't work for devices, but it will work for others. Since EcoFlow doesn't claim it to be a true UPS, I don't see an issue with this. If you need a device with true UPS mode, I'd go with something else. It's acting as advertised and in the owners manual it states it's not meant to replace a true UPS, I think that's why they called it EPS mode. This is great for full size refrigerators. Im not aware of a power station with a true 10ms cuttover feature, most other products on the market offer a 20ms swap over (Oukitel, FFpower, Bluetti, and LemiPower) which is better, but not ideal.
Very good review my friend. Very impressive product. One question, it would be nice if I could charge my 48 volt e-bike battery from DC and or use the e-bike battery as an expansion module to this one. That would give a multy purpose use to both devices. Depending on the need at the time. Because the e-bike charger can only do 2 amps.
Hi Jason, thanks for your informative video! #Greatness! I just received my Delta 2 and wanted to use it for a back up here in Florida during the lightning storms. Specifcally the EPS MODE, do you think it's okay if i leave this plugged in 24/7 for that reason? Would that be wasteful in any way? I plan to keep my office plugged into it, including the router, all the time. I appreciate your suggestion, thank you!
Hi, (sorry for my English)I have delta 2 unit with the extra battery. I used this unit almost every day about a month now and all worked fine. I charged from solar and the extra battery charged up to 100% without problem, but the main unit stopped at 84%. I tried to charge from mains as well and the same. The charge/ discharge level is on 0-100% so shoudn’t be problem. I try to use my tv from ac to take out some charge, but only charged back to 84%. After that switched off the unit and just disconnected the extra battery and I planned to discharge the unit to 0% but the last 1% lasted forever, So I tried to recharge the main unit from main now and hoped will go through on 84%. The main unt said on the screen Will be fully charged just in 25minutes from 1%, charged with 1000watts. Successfully was able to step through the 84% but when hit the 90% suddenly jumped to 100% and stopped charging. What can be the problem? I’m able to use the full capacity off the battery or something went wrong with the battery or the controller software? Thanks for the help
The display percentages aren't exact but I haven't seen my jump around that much. Use the Ecoflow smart app to open a support ticket, see if they will replace or repair the unit. You can also call them on the phone to get support.
Super review like always and super product! Do you think that can be recharged with one Sp200 bluetti panel? And if yes, which cable is necessary? Thanks in advance!
Im guessing will charge in about 4 to 5 hours with that solar panel in excellent solar conditions. You'd want to pick up the adapter see in the video, "MC4 to XT60".
Jason; EcoFlo just came out on June 2, 2024, with their EcoFlo Delta 2 for $599.00. Has this proven to be a good power station for you? One of your videos showed you using a gas/propane generator to charge it.
It's very similar to the AC180 from Bluetti and the Anker SOLIX C1000. I've used the Delta 2 a bit around the house to power shop vacs, grinders, and my corded drills and saws. The 1800 watt inverter makes it useful for most applications but it's still light enough to not be annoying. That's a great price! It seems the pricing war is getting better and better.
We've just run into a HUGE vanlife problem with the EcoFlow units - the 12v output only being 10A across the range of their units! This was not powerful enough for us to start our Bison petrol heater in our van conversion, and something that Ecoflow seems to have glossed over and other competitors in the market have not (Bluetti and Goal Zero both having 20A or more). We are now purchasing a Bluetti AC200 Max to replace our Ecoflow Delta Mini.
@@Jasonoid definitely! The goal zero units also have a high power 12V output. In my opinion this aspect isn’t highlighted enough online, and seems crazy the Delta 2 didn’t see an upgrade in this area
Thanks for sharing this. I have been looking at this and saw another review where the EPS could not keep the computer running during failover. I'm curious now why that is. I'll be looking into this as it might make a good solution for the home office as well as keeping our fridge running during a power outage.
Are you referring to Hobotechs video when he tested with a laptop without a battery? I'm not sure if that's a realistic test since most people use their laptops with batteries. I think testing with a desktop is more realistic. The EPS mode will work fine with some devices and it won't with others. I think it worked with my desktop computer because the power supply has built in capacitors (like all desktop computers) that allow for quick losses of power. I think it should work well for any full size fridge and for most desktop computers. The only way to know would be to test on your specific computer.
Great review. Looks like a very good product. Like the fact they finally went to Lithium Iron Phosphate. One question. What is the power limit of the UPS mode? I assume it is the same as the power charging as plugging it in to the AC outlet. Please verify this. Thanks.
Well these do literal pass through charging, so if you are charging and pulling power it totals up all the wattage over 1200w, so charging at 1200watts plus whatever your load is it will go high. Ecoflow power stations are some of the only power stations with true pass through charging.
really nice power station, maybe even better than my p2001, though i am perfectly happy with it now that it is working properly the fans however are louder by alot, probably right that they could tune them down a bit, maybe use more thermal sense to control them the ups function also looks to be a bit too slow, if your screen goes out, its not going to keep that pc running under load, idle, sure the caps in the psu are probably going to hold it for a couple miliseconds, but since the screen went out i wouldn't count on it being fast enough. the p2001 is faster, but not by much, my pc under heavy load it's also too slow, at idle it's fine. having had a look at hobo tech's video his seems to be even slower also his amp is showing static on the amp test, so maybe you got a slightly better quality one? thanks again for your look into this power station
Our test results were slightly different with the guitar amp testing, which was interesting. I'm guessing each amp will behave differently or the power stations differ slightly. I'll need to try to test the EPS cutoff with the PC under load, that would be interesting to see if it stays powered up with more wattage going through it.
@@Jasonoid If you're going to test it under load, check the power supply inside the PC, and how much it's pulling when running a benchmark like prime 95. My guess despite not knowing anything about that system other than it's probably an office grade inexpensive Dell. I would guess 400 watt psu with a 65 watt cpu, idle draw around 100 watts and loaded at 200. Most of those run best at 50% load. Push the load higher than 80% and the time the caps last is very short. My PC has a psu rated at 1000 watts, idle draw is about 150 watts, if i load up prime 95 and afterburner, it'll pull 800 watts approximately. Add in my screens and that's about 950 watts at the outlet. The p2001 can't handle the switch over in time. But at idle and 350 watts total it's no problem. If you know of a way to test the switch over time, maybe you could count the milliseconds it takes and get visual representation in how many sine cycles are lost in the switch over. If you have a APC Smart UPS, you could measure that then check the power stations and have a comparison. Perhaps your buddy Jeff could help with suggestions? Seems like he knows a fair bit about these things. Or maybe I'll spend some time and research this.
Jason, I’m curious if your default AC setting was at 50Hz, mine was, so I changed it to 60Hz by holding the AC ON/OFF button for 15 seconds per a Reddit post and it worked perfectly
I would have given it a .5 point for the UPS. they don't call it a UPS because of the 30ms time it takes to switch over and Hobotech had issues with it working as a UPS. Otherwise I agree with your score .
There are a lot of issues with this unit and with my 13.2 v standard it only has 77Ah battery ... Three Weize 100 which has cold temp shut off would cost about the same on the pre-sale and I get 300Ah .... Did you look at their list of 1700 or something ... Too little too soon for too much in my opintion.
DIY options will always be cheaper, but they aren't always the best solution. Moving around three 100ah batteries is a lot of work and isn't very portable. This power station is designed to be a small portable setup. The fact that this little box has the battery, 1800w inverter, and 500 watt charge controller in it is pretty impressive. This 'off the shelf' solution isn't for everyone, but it checks a lot of the boxes for a power station.
I have dealt with Bluetti. They asked me to delete negative comments about them and deleted me from their Facebook Group for contesting their fraudulent contests.
I would choose it over the Delta Max 1600wh model, probably not over the Delta Max 2000wh option though. That one is still more powerful and takes in more solar.
Hi - really good review! Only concern/question I have is ... do you see any no-load self discharge? It seems LFP batteries can suffer from charge drain of 1% per week with everything switched off. Have you noticed any drain and if so roughly how fast? For home backup use that would be a con. Thanks again!!
No, I haven't not seen anything like that in my extensive testing. Maybe if you leave the power station running for the week you'll see that type of loss. Turning it fully off you won't lose 1% per week.
i like the ecoflow delta but the cons are, it has only one DC output which is limited to 12v /10ah ,which is good to have 2 DC OUTPUT 12v 30ah in order to run dc fridge,dc fans etc the ups is mode is the second con,not good enough
Delta is already selling at $799 last time I checked. I wouldn’t say inferior in terms of battery chemistry but definitely missing newer features like iot
Maybe the fan speed is set for the highest ambient temperature environment it is rated to work in. Perhaps in more temperate climes it could be reduced.
Went to register it for the warranty and their web site said 24 month warranty. They wanted an image of the purchase order before they would complete the warranty registration. How do you take an image of an email purchase order from Home Depot. Did not get the 5% discount from the coupon after numerous attempts and decided to trust Home Depot and buy from them instead. Home Depot actually has customer service. EcoFlow have a strategy for customer support but it has been designed with something else in mind.
It would be handy if the Ecoflow App had a charging history / graph - a bit like the ones you get on the Victron app. Especially when you're using the bigger systems like the Delta Pro. It's just nice to be able to monitor your solar input and power draw over the course of a day / week. I've asked Ecoflow to add it to their app but do you think it would be possible to connect something like a Victron monitor / shunt to my solar panel and to my Ecoflow, so I can see the charging / solar history, etc? I know that probably seems like overkill, but it's the only option I could think of until Ecoflow give their app an update :)
Just bought both for just over $900 a couple weeks ago with a slickdeal. Wonder if they are making way for newer models? One thing I wished you could do is charge the extra battery without hooking it through the main Delta 2.
I have the Delta 2 with the extra battery. I have it set up to power most of my household electronics and it is connected to 2 solar panels that keep it pretty well juiced. Do you recommend this set up for regular or long term use as a method to reduce overall grid costs?
That's how I use my power stations. I have a reliance controls transfer switch and it's a great way to take specific circuits off grid and power them via solar.
We are looking for a system like this that will run a well pump. Something that can be expanded. Your thoughts on the options out there. Preference on bluetti, ecoflow or others. The easiest for beginners. Thanks for you time and input
greetings buyer beware with bluetti, I purchased AC200P right out box a dud and still fighting with customer service for refund and nothing yet as I search reviews lot of complaints with their backing the product great success in your endeavor
Very nice Overview and good information on Details, thanks! Just one question: the two 12VDC 5521 outputs are rated to have 3A max current, your measurement was 120W output what means 10A. You know the reason for the Differenzen? Anyway I ordered one, looking forward to have it in my Handy!
The printed text displays 3 amps, but the power station allows 10 amps output total. So you can pull up to 10 amps out of one of the ports / all the ports combined. The 5521 connections themselves are not rated for much power or they will get warm/hot over extended runtimes. The safe long term limit for 5521 connections is probably 5 amps, so you could pull 5 amps from each port and be okay. Hope that helps!
Hey! I just got in the ecoflow delta 2 unit 3 weeks after i had recieved the additional battery to connect to it 4 additional wattage..the company had a supply and demand problem and as i use medical equipment,i am having a difficult time in the new unit i recieved even getting the additional battery to "be seen as connected or even charging the extra battery" and i just dont know what the problem is as 2 why,as i hooked up the adfitional battery to the delta 2 1st once i had each unit placed where they were just close enough but far enough 4 air to breath between these units and they are solidly connected using the cord which came w/the additional battery and i plugged the unit into the wall as the #8cord,so it appears 2b,makes it possible,so supposed to in my case,to have both units work in tandem as one or seriesed together to give the delta 2 an additional 1024watts of backup power...well,the main unit is simply not able 2 recognize the additional battery so i have no idea what the problem is as 2 WHY ITS NOT BEING RECOGNIZED GIVEN ITS ATTACHED...AND NOT SHOWING THE EXTRA BATTERY CHARGING....ANY POINTERS AS TO MY PROBLEM??? i bought this to run my medical equipment when power goes out....
@Jasonoid - Solar Power, Batteries, and More Thanks! Great Review! So many choices, now! Smh! They are spitting these generators out like candy! Of the Bluetti, Zendure, and this one ... which one do you think is the best for the money? Your opinion of course ... nothing official?
EcoFlow has excellent customer support and warranties. Each model has their benefits, this one is GREAT for portability since it's only a 1000wh device. I expect they will come out with a larger Delta 2 MAX with LFP eventually that will be better suited for homebackup.
No idea what is inside the case of the Delta2 or the extra battery, but it would be awesome if the Delta 2 could use a 200 ah LiFePO4 like the SOK unit, or if they made a larger battery for power outages.
When connected to an empty or incompletely charged extra battery the power station will shift its own capacity into the battery. In the end you have two half-full or equally charged devices but none at 100%. In order to use the complete original load you now have to carry two heavy units with you instead of only one. In other words: while connected you cannot get a completely charged main unit unless the extra battery is fully charged too. I do not see any benefit from that. What do you thinks is the deeper meaning behind this?
Excellant reviews. I see there is a sale on this and can get it with the 220W Bifacial solar panel. Do you have a better recommendation for a portable panel to use with this? And are there any issues with cold weather usage? Thanks
The 220w panel put's out great power, but it's a little heavy when compared to other panels I have tested. I haven't really tested any power stations at extreme low temps. Anything around 25F or higher the power station makes enough heat to keep itself warm. Lower than that, not sure how it will behave.
Also pity it doesn't have dual charging so you can charge of solar via DC input and add another array via the AC input. If it have a power brick then you could do this.
Hey Jason bought delta 2 so far I’m happpy with it. I plan on buying extra battery after I save up some more cash. I have 2 200 watt newpowa panels. I would like to set them up outside in my yard but can’t figure how to get solar cables inside my house to charge delta.2. I don’t won’t to cut hole in my wall. I do have hole in my floor with an old satellite cable runs thru. Think I might be able to get one cable thru but probably no way for two. Got any suggestions
19:01 they did get it with the original EF-1500 external battery, it is a beast and still rocking away at my place. Regarding : When powering a large external load, will the load be shared between the two batteries so their cycle life is protected?
Did you like the performance of the EcoFlow Delta 2 power station!? Purchase the EcoFlow Delta 2 using the 5% OFF DISCOUNT CODE ( LGL23I6B ):
us.ecoflow.com/?aff=216
Is this delta worth it or to go with OUKITEL.
Definitely liked the performance of the Delta 2. Hopefully I will upgrade by next season
I need this one. Originally I was going to buy bluetti eb3a and 70s, but now I think all I need to buy is the Delta 2 for $1K vs the other two bluetti for $800. Does this one buy make more sense?
LGL23I6B does not work anymore?
Seems people getting different efficiency results for AC & DC. I'm trying to decide on this box but seeing 74% reported except what Jason reported. Anyone reported lower efficiency?
Awesome review Jason. Really great data and presentation! I agree with the tweaks you made to the rating system, that's super helpful to people shopping for units.
Great review, been considering this unit, used the promo code and ordered today with a bonus waterproof bag at no charge. Perfect for camping and hurricane back up to power the fridge.
They finally went LiFePO4!! I think now that they are at the 'standard' (at least for people in the know who are researching), their other value adds (fast charging, 1800W inverter, expansion, backwards compatibility) put them above the competition. They are back on my radar! Thanks for the review, Jason!
I was very excited to hear LFP was inside :) :) :)
@@Jasonoid Is it really inside? How do you know without disassembling?
Yup this is something bluetti doesn't have. I will buy $239 eb3a and this $950 Delta 2 better than 70s can't afford bluetti 2000w unit.
Excellent review; thanks for explaining the lack of independent charging for the extra battery at the 19:00 mark. An area for improvement for EcoFlow on an otherwise good product
Jason after consideration about how I use the delta 2. I have decided that for my purposes, the extra battery would be a waste of money. So I'm buying a second delta 2 instead. Basically we only spend time in two maybe three rooms in the house. Two of those rooms are side by side. The delta 2 can run everything in the kitchen except the range. Out the other one in the master bedroom. I can't do that with the extra battery. If I ever decide to get a transfer switch to run house. I'll be purchasing a larger unit with expandability. Oh and the two rooms next to each other are kitchen and den. The only we run in den are TV and a couple of lamps. What say you.
I think that will work well for what you have described. You can even have one charging while the other on is in use. I love how small and lightweight these are.
Another great review Jason! :) And it wasn't too long at all. A really well made and in depth video. Just what someone needs to see before buying a power station like this. Looking forward to more ecoflow products getting the LifePO4 makeover too.
I've been working really hard to change up my reviews to a faster pace, less wasted time, and still providing the same info. Thanks for the feedback!
Excellent, thorough review. While you said this was a long video I prefer this to a five minute cursory introduction to a $1,000 device. Earlier this year our power was out for almost 18 hours. No AC, no fans, no cooking. I looked at a Milwaukee battery powered fan and that was about $100. A Delta 2 seems like a bargain in comparison since I can run a fan, use a kettle and an induction cooktop. Coffee maker too.
Excellent job. You keep adding new angles in your reviews and I love it. I have been waiting for this unit for awhile. One disappointment is the 60V solar limit. Bluetti had a similar issue with the EB150, then they released the EB240 and raised the voltage a bit. EcoFlow should have made it something like 66V or 70V. In any case, small complaint for a nice unit.
Yeah, you have to have very specific panels to put them in a 3s config. Luckily it allows up to 15 amps input, a large improvement over the 10 amp limit of the EB120/EB150. So you could probably still get max power with a 2S config as well.
FYI: the idle power consumption for the DC output is actually about 3 watts or ~0,3% per hour. The SoC meter just doesn't register it so you could end up with an empty battery a couple of weeks while the Delta 2 is still indicating 100%. Same goes for low power solar charging. If you only input a couple of watts, the SoC stays the same. This has thrown me off the loop a couple of times until I figured it out. I suppose the current shunt isn't accurate enough to produce enough voltage drop at such low currents.
Eco Flow Delta 2 is going to sell all they make! Thank you for the review. I congratulate Eco Flow for getting a 9.5 out of 10 score. Finally, I want to say good for Eco Flow to refer to one of its features as an EPS (Emergency Power Source) and not UPS (Uninterruptable Power Source).
I like how they aren't claiming it to be a true uninterrupted power supply. You can see in my video it worked with the desktop just fine, but failed with the monitor. Some devices will work and some won't as it cuts over. Overall, very good performance for a portable unit.
Got my Delta 2 and solar panels this week. Love that's its expandable to over 3,000wh plugging in the Max battery.
I was disappointed to find that you cannot use the Ecoflow Wave air conditioner AND another battery but I don't think that's an issue for most people. Well you can but not through DC.
Great review thanks so much! About to purchase on Amazon with $250 discount & free waterproof case… this will reduce some anxiety once I receive it. World is getting crazy!
Absolutely is, cheers from Denmark
Very nice that's it has lifepo4! This is more than likely be my next solar generator purchase. These power stations are collectibles with so much utility lol
Thanks for the review df the Delta 2. The fact that it has more than three thousand charge cycles is more than enough reason for me to acquire one.
Note the solar cable they sell is XT60 (yellow) only support 8A, you need XT60i (orange) for 15A which they don’t sell it.
Great information about the difference in cable design, I was curious what the difference was!
I really like that point about the extra batteries just being a way to expand capacity and nothing else. No way to charge or use outside of the main device. I had the idea that, on my Delta Pro, I could use the extra battery to bring outside and charge via solar during the day then bring it back inside to keep the main battery going at night but you can't do that. Shame cause, if you want to use the Delta 2 or Delta pro as your main station and keep it in a specific spot, it could be hard to bring out to wherever power is coming unless you get longer cords or have a setup already installed or something. At least with the Delta 2, it's a looooot easier to carry around, lol. Thanks for the video!
great point, it would be nice if you could use the EcoFlow batteries on their own.
Just like everything else, power stations keep getting better and certainly more expensive. I like that it's lightweight!! I can pick it up and put it where I want it. That's a plus for me! Thank you for the review, Jason!
This one is priced pretty well for the feature set. LFP batteries are less expensive to manufacturer so the prices on these should come down overtime.
Looking through the spreed sheet I didn't see a column related to expandability via additional batteries. That for me would be very helpful as I can take head unit for camping and use expanded setup for more of home backup system if I can add enough batteries. Great videos.
Thanks for the feedback! Great item to list on the spreadsheet
VERY WELL MADE REVIEW, FULL OF INFORMATION. VERY HELPFUL. THANK YOU 10/10
Great video as always! I have a suggestion for a future tests. For solar applications it's crucial to have a good round-trip efficiency in addition to a good inverter and dc circuitry efficiency. Could you also measure the total input energy in kWh needed to charge a solar generator fully? Putting a power meter between the solar array and the MPPT controller input would help in sizing the array. And while you're at it, why not measure the input energy while charging from AC with the Kill a watt you use for inverter output efficiency tests?
There are 3 tubers I follow you included and on the other channel the computer turned off, the relay switch used on the Delta 2 was not fast enough to use as a UPS. Interestingly all 3 of you loaded up the videos today. Just FYI, I understand that if one also owns the Delta Max and you own the expansion battery you can use that battery on the Delta 2. Love your videos and great job on this one too. Keep up the good work.
Those videos came out at the same time since the product was launched that day. We are given a "video launch time" and the video can't come out before then :) Thanks for watching Shelley!
Love your videos. You should add points for warranty and customer service.
Nice unit but think the loud fans and slow "UPS" is a turnoff.
That Delta 2 is indeed a game changer with a short 80 minute charge time. It is actually the fastest charging power station I have ever seen.
I have loved using it around the house since the review. It's so lightweight but so powerful. I will provide a long term update on the channel later.
I'm very likely buying this power staton for charging my e-mountain bike for camping and hunting. The TWO reasons are:
1.) the LFP battery with greatly expanded cycle life over Li-ion stations. 2.) its companion battery expansion, ALSO with LFP battery technology. This expansion battery is mainly for home emergency use.
I plan to charge this when camping/hunting with an Off Grid TREK solar blanket draped over my MAZDA CX-5 windshield and roof with the DELTA 2 locked inside the trunk while I'm away from camp. In the evening I'll simultaneously re-charge my E-MTB's 2 batteries in its patented single charge port.
That's a pretty cool idea! Sounds like it should work well.
Fantastic review, many thanks 😊
This is SO useful. Just found your channel. OUTSTANDING review and comparisons to competing brands. Excellent spreadsheet. Liked and subbed! PLEASE can u compare AC200Max to the Delta Max?? :) :) TWO RIVALS so very similar in WH and price. :) :) (edited: i just realized the Delta Max is not LFP…aka 1/3 life…forget that) Thx Jason!
Hey Ronny! I'm sure EcoFlow will put out a Delta 2 Max (LFP version) sometime in the future. For now the Delta 2 is the only LFP version they offer. I have the AC200max and I will be doing a review video on it later on the channel :)
We just purchase this unit.
We did have the cord for the solar panels included.
Thank you for your detailed review.
I am trying to learn how to get the best use from this power station before we actually need it.
God bless you.
Thank you Jason, love your product reviews. More power to you.
What was your favorite feature on this model?!
Thank U Jason Good to see EcoFlow Move over to LIFEPO4 Take Care Mate
Hey Dr J'
Very, very good information!
Ecoflow is constantly updating their products and I appreciate your prompt dropping of these types of review videos. I think this is the combo I would like to use for our home backup system but the way my checking account is set-up 🤣😂
Thanks for checking out the video, I work super hard to get the reviews out on time! :)
@@Jasonoid You are definitely getting the job done!!!
Unless you live in a shack I don't think this one is going to cut it for that use.
Thank you!!! You just informed an informed buyer.
Excellent review! I will seriously consider getting one. As usual, I am extremely disappointed in the liar-label on capacity, but it otherwise appears to check all the boxes, including the 500W charge rate on solar.
Thanks Joe, I like the features list! Higher capacity would make it better, love that it's expandable too!
I haven't yet come across a single manufacturer who labels the true capacity. Curious how they come up with their numbers.
I don't think they are lying on capacity - the battery cells are rated at 1024wh but there will always be losses with batteries as you pull power from them and convert it into AC power or step down the battery voltage from 48v to 12v. 20% losses are the average in the industry and this is a bit above that.
@@todd.parker That's a move that not many people have noticed or might not even care. They used to be real heavy, now they're lighter than all of them. Less battery, more voltage. I've definitely noticed the loss in conversion. I lose 60 watts an hour with my Bluetti. It's enough to make me reconsider keeping something running 24/7. I think the issue, if there is one, would be that this unit is less efficient than other Ecoflow products.
Thank you for the review. I’m an energy minimalist doing most cooking via 12v and charging with 200watts solar. My only concern is having repaired under warranty.
Ecoflow support has always been responsive both over the phone and email. They replaced my River Pro when it had issues. Give them a call and test it out. See what you think about their service.
I do like the fact that it has around 15 outlets which I can use all at the same time.
Love the video this eco-flow is everything I wanted too bad I just purchased the blue Eddie Max 4 months ago but my next power station will be this eco-flow thank you again I can't wait for your next video
The Bluetti AC200max is a great power station and offers more power than this model. This one is a more portable setup.
Interesting. I just watch the Hobotech video and you have different conclusions from his video on the amp interference and UPS.
Can you elaborate?
@@j-sonS in previous test videos he has plugged the power stations into a heater to test ups functionality. I haven't seen his video this morning, but as you can see from my testing, the UPS mode works just fine for sensitive electronics. My PC didn't turn off after testing it multiple times 🤷
@@Jasonoid This time Hobotech used a laptop with the battery removed as the test load, and it powered off during the switch. I guess his test unit may have a fault with its UPS relay.
Glad to see your unit give better results!
@@j-sonS I think the differences can be chalked up to the different PCs and amps each used. Hobotech was using a really ancient laptop and Jason seemed to be using a more modern PC that maybe can handle longer power blips. Same with the amps - Jason's might just be better shielded?
It's also possible Hobotech had a earlier review model, Jason's seemed a bit better optimised with the car charging too. Maybe they watched Hobotech's review and tweaked a few things. Always going to be variations in units at this price too. Either way this is a great review video Jason thanks
I like these reviews you do, very helpful. Thanks
I have the River Max and the River Pro with the extra battery, I will be adding this one to my collection in November, that is when I will have enough money saved for it . 😎😎
I have been using this one around the yard a bunch since it's so lightweight. For example I needed a bright LED work light out in the yard after dark. Instead of pulling out a 100 foot extension cable and running it from the house, I just plugged the light into this haha!
The fan noise is not a deal breaker, especially when the fan noise scales downward when charging/discharging with less watts
Thanks for your feedback. I love how you can change the charge speed on the app. Most power stations don't offer that feature. Charge anywhere from 200 watts up to 1200 watts!
Very thorough review! Thanks!
I'd like to see the River Pro and extra battery in Lifepo4. As always love your content.
Coming soon!
Great review. Very in-depth! Thank you!
Thanks Chad! If you have any other tests you'd like to see let me know!
Really enjoy your videos. I’m looking at buying a portable power station to power my Snomaster CL56D fridge/freezer. I will have it in my work truck and I am trying to figure out the best way to charge it while I’m driving. The fridge does allow you to have both AC and DC connected, but will default to AC power if connected. If I’m right I could use the portable power station to charge while driving while running the fridge off AC power on the pack. Once the truck is shut off the power pack will disconnect from charging and the fridge will switch to DC power in the power pack.
Awesome review Jason really well done. Looks like a great unit. Wish the UK price would come down a bit though, 1100 pounds here. Maybe they will try selling combo's for cheaper. Cheers
Sheesh, that is a bit more expensive! I'm sorry David!
I need more than 1 cigarette plug. Can I use a double cigarette plug in one for this?
This is really good well rounded review!
Thanks Iamgroot!
What is the efficiency while pulling from the usb c ports ?
The USB ports are more efficient than using the AC inverter, it's hard to track an exact number over USB.
Hi all,
So....I have a hack that I literally just thought of for people who can't afford another Delta Pro or extra battery BUT need additional power and own another ecoflow battery. I have called ecoflow and given them the idea as well and they confirmed that it will in fact work!! I then asked them why they don't tell everyone after I've told them and they said they would "escalate the idea" to their top tier and perhaps add it to their FAQs. So here's the idea: We've been told that you must have like systems in order to use them together. This is NOT actually true. If your Delta Pro is low on power (or any other ecoflow system you have) you can simply plug its charging cable (in the rear) into the front of the secondary system. In other words you're using the second system as a wall outlet of sorts. This works especially well in the evening when the sun is down and there is no more backup energy. What do you do when the sun is up?...even better...plus the second system from the rear into the front of the Delta Pro. This allows the sun to charge them BOTH regardless of the differences of their capacities or sizes!!! The only word of caution they gave me after saying what a great idea this was, was to say don't forget to lower the charging speed on the Delta Pro once it's plugged into the front of the second system. Guys this means you can use anything from a River and up to charge your Delta Pro OR any other ecoflow system. If this works for you please like my comment and say "Thanks T!!" just so I'll know at least I was able to communicate something helpful to the solar community-especially since these systems are sooooo expensive!!
Excellent review with good flow.
Thanks! You'll probably like some of my other videos 😁👍
Jason, unfortunately HoboTech had different results when testing this EF specially on UPS & interfacing.
I wouldn't say they were different results, he just tested a different device. I saw that he tested a laptop without a battery. I like to give realistic tests in my videos so I'm not sure how many people use laptops without batteries on a daily basis. Under some circumstances the EPS mode with the 30ms cuttover won't work for devices, but it will work for others. Since EcoFlow doesn't claim it to be a true UPS, I don't see an issue with this. If you need a device with true UPS mode, I'd go with something else. It's acting as advertised and in the owners manual it states it's not meant to replace a true UPS, I think that's why they called it EPS mode. This is great for full size refrigerators.
Im not aware of a power station with a true 10ms cuttover feature, most other products on the market offer a 20ms swap over (Oukitel, FFpower, Bluetti, and LemiPower) which is better, but not ideal.
Very good review my friend.
Very impressive product.
One question, it would be nice if I could charge my 48 volt e-bike battery from DC and or use the e-bike battery as an expansion module to this one.
That would give a multy purpose use to both devices.
Depending on the need at the time.
Because the e-bike charger can only do 2 amps.
Hi Jason, thanks for your informative video! #Greatness! I just received my Delta 2 and wanted to use it for a back up here in Florida during the lightning storms. Specifcally the EPS MODE, do you think it's okay if i leave this plugged in 24/7 for that reason? Would that be wasteful in any way? I plan to keep my office plugged into it, including the router, all the time. I appreciate your suggestion, thank you!
30ms delay on transfer switch is too long. Hopefully they can address with firmware update. Great review as usual.
That would be pretty cool but I'm sure it's more of a hardware design. Thanks for watching Matt :)
Hi, (sorry for my English)I have delta 2 unit with the extra battery. I used this unit almost every day about a month now and all worked fine. I charged from solar and the extra battery charged up to 100% without problem, but the main unit stopped at 84%. I tried to charge from mains as well and the same. The charge/ discharge level is on 0-100% so shoudn’t be problem. I try to use my tv from ac to take out some charge, but only charged back to 84%. After that switched off the unit and just disconnected the extra battery and I planned to discharge the unit to 0% but the last 1% lasted forever, So I tried to recharge the main unit from main now and hoped will go through on 84%. The main unt said on the screen Will be fully charged just in 25minutes from 1%, charged with 1000watts. Successfully was able to step through the 84% but when hit the 90% suddenly jumped to 100% and stopped charging.
What can be the problem? I’m able to use the full capacity off the battery or something went wrong with the battery or the controller software? Thanks for the help
The display percentages aren't exact but I haven't seen my jump around that much. Use the Ecoflow smart app to open a support ticket, see if they will replace or repair the unit. You can also call them on the phone to get support.
@@Jasonoid Yes that's the plan. Thanks
Super review like always and super product! Do you think that can be recharged with one Sp200 bluetti panel? And if yes, which cable is necessary? Thanks in advance!
Im guessing will charge in about 4 to 5 hours with that solar panel in excellent solar conditions. You'd want to pick up the adapter see in the video, "MC4 to XT60".
Thanks a lot!😊
Jason; EcoFlo just came out on June 2, 2024, with their EcoFlo Delta 2 for $599.00. Has this proven to be a good power station for you? One of your videos showed you using a gas/propane generator to charge it.
It's very similar to the AC180 from Bluetti and the Anker SOLIX C1000. I've used the Delta 2 a bit around the house to power shop vacs, grinders, and my corded drills and saws. The 1800 watt inverter makes it useful for most applications but it's still light enough to not be annoying.
That's a great price! It seems the pricing war is getting better and better.
We've just run into a HUGE vanlife problem with the EcoFlow units - the 12v output only being 10A across the range of their units!
This was not powerful enough for us to start our Bison petrol heater in our van conversion, and something that Ecoflow seems to have glossed over and other competitors in the market have not (Bluetti and Goal Zero both having 20A or more).
We are now purchasing a Bluetti AC200 Max to replace our Ecoflow Delta Mini.
The Bluetti power stations are some of the ONLY units that offer more than 10 amps output, pretty big advantage!
@@Jasonoid definitely! The goal zero units also have a high power 12V output. In my opinion this aspect isn’t highlighted enough online, and seems crazy the Delta 2 didn’t see an upgrade in this area
@@froth_van most people that need high DC power just run stand alone lifepo4 batteries and an inverter.
Thanks for sharing this. I have been looking at this and saw another review where the EPS could not keep the computer running during failover. I'm curious now why that is. I'll be looking into this as it might make a good solution for the home office as well as keeping our fridge running during a power outage.
Are you referring to Hobotechs video when he tested with a laptop without a battery? I'm not sure if that's a realistic test since most people use their laptops with batteries. I think testing with a desktop is more realistic.
The EPS mode will work fine with some devices and it won't with others. I think it worked with my desktop computer because the power supply has built in capacitors (like all desktop computers) that allow for quick losses of power.
I think it should work well for any full size fridge and for most desktop computers. The only way to know would be to test on your specific computer.
I’d like to see it power a home refrigerator and large basement freezer
This looks like a good pick for long term. Will you be doing a review of the Anker 757?
I don't have that one on my short list right now but it seems to be a great option!
Great review. Looks like a very good product. Like the fact they finally went to Lithium Iron Phosphate. One question. What is the power limit of the UPS mode? I assume it is the same as the power charging as plugging it in to the AC outlet. Please verify this. Thanks.
Well these do literal pass through charging, so if you are charging and pulling power it totals up all the wattage over 1200w, so charging at 1200watts plus whatever your load is it will go high. Ecoflow power stations are some of the only power stations with true pass through charging.
really nice power station, maybe even better than my p2001, though i am perfectly happy with it now that it is working properly
the fans however are louder by alot, probably right that they could tune them down a bit, maybe use more thermal sense to control them
the ups function also looks to be a bit too slow, if your screen goes out, its not going to keep that pc running under load, idle, sure the caps in the psu are probably going to hold it for a couple miliseconds, but since the screen went out i wouldn't count on it being fast enough.
the p2001 is faster, but not by much, my pc under heavy load it's also too slow, at idle it's fine.
having had a look at hobo tech's video his seems to be even slower
also his amp is showing static on the amp test, so maybe you got a slightly better quality one?
thanks again for your look into this power station
Our test results were slightly different with the guitar amp testing, which was interesting. I'm guessing each amp will behave differently or the power stations differ slightly. I'll need to try to test the EPS cutoff with the PC under load, that would be interesting to see if it stays powered up with more wattage going through it.
@@Jasonoid If you're going to test it under load, check the power supply inside the PC, and how much it's pulling when running a benchmark like prime 95.
My guess despite not knowing anything about that system other than it's probably an office grade inexpensive Dell.
I would guess 400 watt psu with a 65 watt cpu, idle draw around 100 watts and loaded at 200. Most of those run best at 50% load. Push the load higher than 80% and the time the caps last is very short.
My PC has a psu rated at 1000 watts, idle draw is about 150 watts, if i load up prime 95 and afterburner, it'll pull 800 watts approximately. Add in my screens and that's about 950 watts at the outlet. The p2001 can't handle the switch over in time. But at idle and 350 watts total it's no problem.
If you know of a way to test the switch over time, maybe you could count the milliseconds it takes and get visual representation in how many sine cycles are lost in the switch over. If you have a APC Smart UPS, you could measure that then check the power stations and have a comparison.
Perhaps your buddy Jeff could help with suggestions? Seems like he knows a fair bit about these things. Or maybe I'll spend some time and research this.
Hi Jason. Another good review however I don't see a link to your comparison chart in description or comments, is the link available?
You can find it here on my Website! jasonoid.com/powerstations/
Jason, I’m curious if your default AC setting was at 50Hz, mine was, so I changed it to 60Hz by holding the AC ON/OFF button for 15 seconds per a Reddit post and it worked perfectly
the setting was / is 60hz, this unit works great and I use it all the time.
It’s also able to plug in a generator and if there’s no solar then at. 20% the new generator will start. If you’re solar available it will change.
yes, the EcoFlow smart generator works really well with this model!
I would have given it a .5 point for the UPS. they don't call it a UPS because of the 30ms time it takes to switch over and Hobotech had issues with it working as a UPS. Otherwise I agree with your score .
Good thinking!
There are a lot of issues with this unit and with my 13.2 v standard it only has 77Ah battery ... Three Weize 100 which has cold temp shut off would cost about the same on the pre-sale and I get 300Ah .... Did you look at their list of 1700 or something ... Too little too soon for too much in my opintion.
DIY options will always be cheaper, but they aren't always the best solution. Moving around three 100ah batteries is a lot of work and isn't very portable. This power station is designed to be a small portable setup. The fact that this little box has the battery, 1800w inverter, and 500 watt charge controller in it is pretty impressive. This 'off the shelf' solution isn't for everyone, but it checks a lot of the boxes for a power station.
Excellent review
Thank you!
Nice upgrades - still not a fan of the case design, one of reasons I purchased a bluetti was it's box/hookups. 😊
I'm glad there's options around to please everyone! Choose what works best for you :)
I have dealt with Bluetti. They asked me to delete negative comments about them and deleted me from their Facebook Group for contesting their fraudulent contests.
EcoFlow has a fall sales with a nice discount on the Delta Max. Would you still choose the Delta 2 over the DeltaMax (1600w)?
I would choose it over the Delta Max 1600wh model, probably not over the Delta Max 2000wh option though. That one is still more powerful and takes in more solar.
The best update they could do on this is to allow two units to be connected together...that would be a game changer...!
That would make an interesting combo!
@@Jasonoid Too right...
Hi - really good review! Only concern/question I have is ... do you see any no-load self discharge? It seems LFP batteries can suffer from charge drain of 1% per week with everything switched off. Have you noticed any drain and if so roughly how fast? For home backup use that would be a con. Thanks again!!
No, I haven't not seen anything like that in my extensive testing. Maybe if you leave the power station running for the week you'll see that type of loss. Turning it fully off you won't lose 1% per week.
@@Jasonoid Thank you sir!
Great video Jason!
Appreciate the feedback, David!
i like the ecoflow delta but the cons are, it has only one DC output which is limited to 12v /10ah ,which is good to have 2 DC OUTPUT 12v 30ah in order to run dc fridge,dc fans etc
the ups is mode is the second con,not good enough
Does this mean big discounts in the inferior older models with the Lithium Ion batteries?
Delta is already selling at $799 last time I checked. I wouldn’t say inferior in terms of battery chemistry but definitely missing newer features like iot
Possibly! I use my Delta Max all the time, Its still an absolute beast....just not as long lasting battery.
@@Jasonoid us the delta max better option or bluetti ac200max
Thanks and nice presentation.
Maybe the fan speed is set for the highest ambient temperature environment it is rated to work in. Perhaps in more temperate climes it could be reduced.
nope, it wouldn't ... these are not a PWM fans - they are spinning on two speeds, max and none
Went to register it for the warranty and their web site said 24 month warranty. They wanted an image of the purchase order before they would complete the warranty registration. How do you take an image of an email purchase order from Home Depot. Did not get the 5% discount from the coupon after numerous attempts and decided to trust Home Depot and buy from them instead. Home Depot actually has customer service. EcoFlow have a strategy for customer support but it has been designed with something else in mind.
It would be handy if the Ecoflow App had a charging history / graph - a bit like the ones you get on the Victron app. Especially when you're using the bigger systems like the Delta Pro. It's just nice to be able to monitor your solar input and power draw over the course of a day / week.
I've asked Ecoflow to add it to their app but do you think it would be possible to connect something like a Victron monitor / shunt to my solar panel and to my Ecoflow, so I can see the charging / solar history, etc? I know that probably seems like overkill, but it's the only option I could think of until Ecoflow give their app an update :)
There might be an inline shunt that you could put on the solar panel wires to track your daily power.
Just bought both for just over $900 a couple weeks ago with a slickdeal. Wonder if they are making way for newer models? One thing I wished you could do is charge the extra battery without hooking it through the main Delta 2.
The 'Delta 2' with LFP batteries is still really new. Probably not for another year or so.
I have the Delta 2 with the extra battery. I have it set up to power most of my household electronics and it is connected to 2 solar panels that keep it pretty well juiced. Do you recommend this set up for regular or long term use as a method to reduce overall grid costs?
That's how I use my power stations. I have a reliance controls transfer switch and it's a great way to take specific circuits off grid and power them via solar.
We are looking for a system like this that will run a well pump. Something that can be expanded. Your thoughts on the options out there. Preference on bluetti, ecoflow or others. The easiest for beginners.
Thanks for you time and input
greetings buyer beware with bluetti, I purchased AC200P right out box a dud and still fighting with customer service for refund and nothing yet as I search reviews lot of complaints with their backing the product great success in your endeavor
Very nice Overview and good information on Details, thanks! Just one question: the two 12VDC 5521 outputs are rated to have 3A max current, your measurement was 120W output what means 10A. You know the reason for the Differenzen? Anyway I ordered one, looking forward to have it in my Handy!
The printed text displays 3 amps, but the power station allows 10 amps output total. So you can pull up to 10 amps out of one of the ports / all the ports combined. The 5521 connections themselves are not rated for much power or they will get warm/hot over extended runtimes. The safe long term limit for 5521 connections is probably 5 amps, so you could pull 5 amps from each port and be okay. Hope that helps!
Hey! I just got in the ecoflow delta 2 unit 3 weeks after i had recieved the additional battery to connect to it 4 additional wattage..the company had a supply and demand problem and as i use medical equipment,i am having a difficult time in the new unit i recieved even getting the additional battery to "be seen as connected or even charging the extra battery" and i just dont know what the problem is as 2 why,as i hooked up the adfitional battery to the delta 2 1st once i had each unit placed where they were just close enough but far enough 4 air to breath between these units and they are solidly connected using the cord which came w/the additional battery and i plugged the unit into the wall as the #8cord,so it appears 2b,makes it possible,so supposed to in my case,to have both units work in tandem as one or seriesed together to give the delta 2 an additional 1024watts of backup power...well,the main unit is simply not able 2 recognize the additional battery so i have no idea what the problem is as 2 WHY ITS NOT BEING RECOGNIZED GIVEN ITS ATTACHED...AND NOT SHOWING THE EXTRA BATTERY CHARGING....ANY POINTERS AS TO MY PROBLEM??? i bought this to run my medical equipment when power goes out....
Will sending back my new bluetti eb70s and get this one.
This does offer quite a bit more over the EB70, it's also more expensive. Either option would work well in specific use cases.
I really really need one bad ! But living on a fixed income I need something that good but cheap ! But this seem to be a great product.
Check out the Pecron 2000lfp model. If you're looking for a 2000wh budget option, it's one of the best!
@Jasonoid - Solar Power, Batteries, and More Thanks! Great Review! So many choices, now! Smh! They are spitting these generators out like candy! Of the Bluetti, Zendure, and this one ... which one do you think is the best for the money? Your opinion of course ... nothing official?
EcoFlow has excellent customer support and warranties. Each model has their benefits, this one is GREAT for portability since it's only a 1000wh device. I expect they will come out with a larger Delta 2 MAX with LFP eventually that will be better suited for homebackup.
I was wondering if the firmware updates have improved the UPS Mode Under 20MS test on the Delta 2? I know it helped on the Delta 2 Max...
I haven't seen any firmware updates mentioning a faster UPS mode on the Delta 2.
Sad about the fan noise, on an otherwise great product. With 3t cycles more people will be use it on an ongoing basis.
Anyone think the Ecoflow will come on sale next year ? I looking at the Delta max 2000 but its pricey imo.
They are on sale for BlackFriday right now, they do sales during the larger holidays
No idea what is inside the case of the Delta2 or the extra battery, but it would be awesome if the Delta 2 could use a 200 ah LiFePO4 like the SOK unit, or if they made a larger battery for power outages.
Ecoflow did a tear down of the Delta 2 on their youtube channel, you could get some ideas from that
When connected to an empty or incompletely charged extra battery the power station will shift its own capacity into the battery. In the end you have two half-full or equally charged devices but none at 100%. In order to use the complete original load you now have to carry two heavy units with you instead of only one. In other words: while connected you cannot get a completely charged main unit unless the extra battery is fully charged too. I do not see any benefit from that. What do you thinks is the deeper meaning behind this?
Excellant reviews. I see there is a sale on this and can get it with the 220W Bifacial solar panel. Do you have a better recommendation for a portable panel to use with this? And are there any issues with cold weather usage? Thanks
The 220w panel put's out great power, but it's a little heavy when compared to other panels I have tested. I haven't really tested any power stations at extreme low temps. Anything around 25F or higher the power station makes enough heat to keep itself warm. Lower than that, not sure how it will behave.
I just wish Ecoflow delta 2 (and delta pro) weren't so noisy. It's a deal breaker for me.
Also pity it doesn't have dual charging so you can charge of solar via DC input and add another array via the AC input. If it have a power brick then you could do this.
Yeah, with only one DC input port it limits your charging options.
Hey Jason bought delta 2 so far I’m happpy with it. I plan on buying extra battery after I save up some more cash. I have 2 200 watt newpowa panels. I would like to set them up outside in my yard but can’t figure how to get solar cables inside my house to charge delta.2. I don’t won’t to cut hole in my wall. I do have hole in my floor with an old satellite cable runs thru. Think I might be able to get one cable thru but probably no way for two. Got any suggestions
When you did your discharge test, did you have the battery (via the app) set to stop discharge at a certain percentage or to fully discharge?
Fully discharged!
Do you know if the Delta 2 supports dual charging? I mean ac-charging up to a percentage en the rest on solar like some Bluetti''s do.
I didn't get a chance to test it out in the video, but I'm sure it supports dual charging. I'll have to test that out soon!
19:01 they did get it with the original EF-1500 external battery, it is a beast and still rocking away at my place.
Regarding : When powering a large external load, will the load be shared between the two batteries so their cycle life is protected?
When testing it usually is being charged by the external battery when you run a load
