- This is a refurbished unit from Ecoflow. It is quite cheap and what a deal I got! But how good is a refurbished unit and is it worth the money? I'm also going to show you something you should know if you own this unit already or if you're thinking about purchasing this unit in a near future. Let's find out!
Nice review, a couple of notes though.
1. In your capacity test you stopped at 5%, but you should have run it to 0% because the meters are not always entirely accurate.
2. With the external battery you can absolutely output a full 1800 W, even though the DC input is far less because the Inverter is running off the battery, not the input.
3. In your solar charging time remaining test, Yes, that meter is notoriously inaccurate but just because the controller shows input doesn't mean the BMS battery management unit is dumping that entire load into the battery. It's a pretty good BMS, it keeps track of the state of charge of the battery and there's no danger of it being fried because you left it plugged into solar panels really. The original Delta 1300 has been out for four years and nobody's had a problem with that.
4. There is nothing wrong with charging these batteries to 100%. For one thing, there is some battery reserve you can't see. But even top-of-the-line battery manufacturer Battleborn states there's nothing wrong with charging a lithium ion battery 0% to 100% and there is no memory effect.
And for an occasional user, say someone who cycles it once a week 52 times a year, it will take over 15 years to reduce the capacity by 20% (800 cycles to 80%) and you will still have 80% capacity, so calendar aging will obsolete this device before battery cycling does.
Now for daily cycling, it is better to buy a LFP lifepo4 battery unit which has 3500 cycles to 80%.
But with these NCM units limiting charging 10% to 90% means you're sacrificing 20% of your capacity today, to save that same capacity in 15 years. It really doesn't make sense. It's better just to use it today. It's a great bang for your buck for the occasional user and look how much the prices come down in the last four years.
But the idea that you have to sit there and monitor the solar input is overkill really. The BMS is smarter than you are and this is a peace of mind product, you don't have to baby it.
Great deal. I had reached out to them right after the promotion ended and they were able to price match. Ended up getting one in new condition for 458 w/ tax.
CS rep informed me that they guarantee their units have atleast 95% battery health on their refurbished items
It was out of calibration as it balances the cells in the final stage of charging. I bet if you charged it up again it won't take that long. It's usually around 10-15min while displaying 100% before it's done on AC and even longer on solar. The screen is an estimate and the efficiency depending on the rate of charge can be below 80% and is well documented.
Another Killa vid mate.
Two thumb up from me on how informative that review was on a refurbished unite with pro and con. The extent of your passion to mod it to next level is amazing. U r my new hero mate. GOING to work on Monday and shall spread your channel to whole Canningvale Markets here in Auz.
Only just come across your channel today because I needed some info to install speed controller for my E bike. Which i did but 6 hours later still watching. Fair effort mate.
Love this stuff.
Thanks for the insight and for giving people a new, recent space to collect thoughts on refurbished products.
Great video, I have been looking at the power bank, glad to see you tested exactly what I was concerned about. Thanks Joe
You deserve way more subs and way more attention, you keep teaching us a lot of useful and interesting stuff, stay safe man.
Bro this guy is like a goldmine of information, he’s the reason I tear down power tool batteries and make the cells into new packs
He introduced me to bigclive and greatscott and now I’m even going to try out an electronics course so I can have some more insight into this stuff
@@guymee same basically, love electronics, and love the content he brings cause he knows all the stuff that really matters to us and not what big companies say (that really doesn't matter or is not true) i hope he never stops uploading videos
@@tuna5748 exactly, like he’ll tell us about the big company marketing and his actual experience with their products
I’ve had the same problem with displays for these as well, with it saying that it’s full for a really long time, and then only letting myself charge it when I’m around since I don’t want it to just burst into flames or something
He’s got so much info
totally agreed
people hardcore can see he takes to the max
attention to details are exceptional.
Good review. One thing i would point out is that if you get their app you can set it to when do you want battery to stop charging. I set it to 90% if it's plugged in to solar. I had my river pro for over a year now and so far i am pretty happy with the company. I wish they expended the app so it had more customization but it's still good
This model can’t be connected to the app. It doesn’t have Bluetooth or Wi-Fi, thats one of the reasons it’s so inexpensive.
Itsxa 3 year old design when you tested it. All of EF second generation units are top of the line.
I'm Asian and you sir have the best fake Asian accent or you truly represent the very replicated accent. Applaud you sir.
I can't tell if it's Asian, South African or New Zealand... or all three at the same time.

I bought One New from Amazon on Black Friday with 5 year Warranty and 160 Watt Portable Eco Flow Solar Panel $705.00 and a refurbished Unit for $523.11 off Ebay with 2 Year Warranty and a refurbished Eco Flow 160 Watt Portable Solar Panel plus an Additional 110 Watt Panel and 2 year warranty as well and later a River Pro 2 for $250.00 off Ebay with a 5 year warranty and Bluetooth and App included. Very Happy with All 6 Items. And less than $0.50 Cents a Watt across the board.
Man this gives me some insight,
I grabbed a power station on Amazon that was 2000 ish watt hour, but the display is just horribly violently inaccurate
I have an in line meter showing the watts from my solar, and the watts it’s displaying is roughly 10 above the actual input
Also the battery gauge is horribly far off from real life, says shit like 100% for up to 2 days of around 380WH
The MPPT controller it uses seems to get absolutely ripping hot on the inside before the fans kick in
And the worst part, the DC jack for regulated 6S lithium ion charging at 7.3 amp
That thing if I rest the back of my fingers on it, it’ll arc the hair and give me a zap!!
It was 1600 dollars with 250 off, for over 2000WH, which sounds good but keep in mind it’s lithium Ion not LiFePO4
All in all though, seeing that these things often have innacuracies in their displays calms me down
Especially since I know the BMS kicks in and stops the charge, but I also know I probably shouldn’t take it for granted too much
thank you so much
I wish I could send you my battery to test. I got a smaller eco flow and it has a wonky AC output. When I plug in lights they have a tiny flash every couple of seconds. Wonder what's causing it
when you plug in the external nissan leaf battery, does it handle low voltage cut-off? will the ecoflow drain the external battery completely dead and ruin the battery?
Do you remember seeing one of tjese battery banks that can accept 95v PV input? I have a TON of solar, but it's all high voltage.
Use a charge controller between your panels and whatever battery bank you’re using.
Hi first comment because of you im opening electric scooter now 😂
Connect it to an inductive load and then show us the waveform. Thanks
Is the 12v output on the back regulated? If not you can see how much solar overcharges the battery.
The internal bms will disconnect and stop charging . The bms has overvoltage and overcurrent protection
Were they running a promo? All I see currently is $599. Did they send you a discount and a coupon?
Yes, they were running a promo. If you don't need it now, just wait. They will run a promo once in a while.
I have a question for you, I saw it works for me I was wondering if you’ve tried since you’re definitely more of an expert on me on this front
So i made a few XT60 series connectors when I was getting into soldering last summer
I noticed if your solar panel voltage is so low that your power station input wattage cuts off at its full amperage (mine for example takes around 7.3 amp max)
And my meter shows my panels only ever get to about 20V with full MPPT, but the station can take up to 30v MPPT
So I put a large capacity 1S10P lithium pack in series with the panels to get significantly more watts just from adding the voltages
I imagine it’s safe since the current is regulated, and the current seems to be entirely based on the solar panels ability to put out current, which I think is safely balancing the current from the battery pack, and according to my DC clamp meter, it seems to be true that the panels current will just follow what it can do, but also this strategy makes it so that when the solar watts drop below let’s say 20, if I leave this battery in series, it’ll continue to slow charge even when the solar input drops very low
Obviously the aux battery is putting out very little current as well, but I was curious if you’ve tried this
Mainly because of the concept of plugging your 40V of solar in, but you still have 35 volts before you hit your limit, so you could throw maybe even an 8S battery in series with the panels to get the most bang for your buck based on time
Though I understand there’s a lot more hassle with plugging extra batteries and soldering connectors, I was just curious if you r tried this, especially since XT60’s seem to be so consistent with all these power stations at least internally
The charge controller, was probably set. For two hours. Of float time.
would you be able to charge the ecoflow delta as well as the external battery with the delta wall charger?
Ecoflow efficiency on most of their products is 78% Bluetti is about 86% VTOMAN is 85% most older Ecoflow don’t use Lifepo4 batteries so you’ll get 800 cycles to 80% or so they say but I’ve done testing that shows after around 800 cycles Ecoflow is at about 70% efficiency well built but I wouldn’t recommend it
It's refurbished because it uses cheap, high frequency, transformerless inverter tech. I wouldn't use one of these, even if they were giving them away.

At 0:32. If you look at the bottom part of the screen, you'll see it says "2-year warranty included"

I ordered x2 Ecoflow Delta 2 that cost around 2,600 dollars. . I had called customer service to cancel them right away and I was assured that they won't be charging me for shipping because I won't get the products anyway.
After 2 weeks. They charged me shipping cost on the first order plus penalty of more than 4%. They stated that penalty is 2.6%. I felt those penalties were too much for items I have not even touched. They refused to refund me on the second order citing system error on their part.
Ecoflow are thieves who robbed their customers. Please don't purchase any Ecoflow products. Very bad customer service.
