(Update) This has been a controversial topic. In response, Yoshino has provided more information and test results related to their solid-state battery implementation here: yoshinopower.com/pages/solid-state-technology My goal with this video was to test the performance of this portable power station and see if it can deliver the power output that it claims. I hope my practical testing helps you draw your own conclusions about this unique power station.
WOW!!! I was just going to ask if you saw any of those destructive tear downs of this battery.
I guess it just boils down to the definition of what a solid state battery is. I don't go for their definition above but I will be trying to find out more about what a solid state battery is. Also I would never buy this power station if only because of the limited solar input!
@@RVwithTito It is also called plastic battery. They are just full of it. That was a liion cell like any other.
@@LarryRichellilook up part number QT-114103310 this is the battery used listed as rechargeable lithium ion not solid state or anything else. Right on the safety data sheet with the companys name on it.
Someone disassembled one. It’s housing standard lithium ion pouch cells. Definitely not solid state
Came back to this video to make the same comment. Others should reply to your comment to promote it. These are more dangerous than LiFePO4.
This is true it's not actually solid state
Yes. I've been following this. I reached out to Yoshino for comment on this. They responded promptly (see response below) and updated their website with more info about their solid-state implementation and test results.
yoshinopower.com/pages/solid-state-technology
Originally, I asked if the battery cells are 100% solid-state or semi-solid state. Their response: "Our solid-state batteries consist of 95% pure solid electrolytes and 5% liquid catalysts."
Here was Yoshino's response to other UA-camr claims about the Yoshino battery cells:
Yes, we have seen these videos and it is very disappointing as they are not only abusing the battery beyond any scientific testing methodology, but they are very irresponsible by saying it must indicate it isn’t solid-state.
The definition of a solid-state cell is one that uses a solid electrolyte in place of a liquid or gel electrolyte. We do in fact use a composite electrolyte recognized by the scientific community as solid-state.
We know the general public has a hard time wrapping their heads around what a solid-state battery is. They think it’s only one thing (and should be like a piece of granite) when in reality there are many different ways of constructing a solid-state battery. All the big names we read about in the news are making their own versions based on this same principle, but with different materials, processes, etc..
Furthermore, any lithium battery subjected to extreme abuse can be made flammable. This is not an indicator of anything scientific and especially does not correlate to whether it’s solid-state or not.
The bottom line is we have a battery that meets the definition of solid-state and that is further evidenced by the benefits we achieve in terms of safety, energy density and life cycles.
We tell our customers that at the end of the day, no one has a better battery in a portable power station - and that is what should guide their decision making.
@@RVwithTitoyou need to take down this video and post one about this scam. Most people don’t read text.
@@RVwithTitowhere is the pinned comment? At this point you look to be part of this scam.
Super important to differentiate between power and energy. So that unit produces 4000 W of continuous power, and it has an energy storage capacity of 2600 W-hours. Or 2.6 kWh. people get their units screwed up all the time and it just confuses everyone.
good point..its just content creator bro
Yes he talks about the capacity then cited 4000 w of continuous power. 2.6 kwh isn't that big or impressive. Other lfp systems are the same size and can do that.
I totally thought this was 4kwh until seeing this comment.
Wow that is super neat, but at $3000 it would have to come down a bit. For about $500 you can get 2 100
Ah li time batteries and $400 for an inverter I’ll save the $2000 and deal with the extra size.
One can always make something cheaper, less convenient or of a lower aesthetic. Always. There is no limit to how low quality a $200 battery, or $400 4000w inverter might be. Not to mention (you didn't) the cost of a good rapid charger. Many of your fellow viewers are well aware of the DIY mentality and want nothing to do the massive conflagration that you have described. I have built solar systems of all sizes and at this point in my life would rather just order one of these and be done with it. I would rather be fishing with my grandkids.
You can't buy a 4000W inverter for $400 and you're missing a charger. You could buy a good quality 4000W solar hybrid inverter and a 48V 2.4kWh rack mount battery, cables, fuses etc but you'd be spending similar money for a little more solar capacity and a 240V outlet. I think given the compactness and portability I could only build something less convenient for less money.
@@geraldhenrickson7472 like I said. Building A cheaper one would be less awesome. And this is awesome. And building something definitely isn’t for every situation. I hope this solid state stuff takes off the size difference is amazing. 😍
Well, capacitors cost more to produce than batteries but should last longer.
@@paulschimel3572 that may be true, but that's a bunch of hokey pokey hobby gear. These types of all in one in a box are super convenient for the lay person..
Great video! I purchased that unit last year and has not failed me. I use it to plug my Rv refrigerator when traveling. Keeps me from having to turn on the propane or turn it off when going through tunnels. I prefer to travel with my propane off. I now have two units one inside the Rv and one at home.
Glad to hear it's working well for you.
I just saw other videos and while your answer was 100% correct, I now understand better. Good job, as always.
I'm glad!
I would only add, this is a first generation power station. I suspect these units will get increasingly better as the price point drops. Also, solid state is safer and more dense at the same time. This might be the future of emergency solar gens. I'm actually stunned they got solid state out like this.
Yeah, I’m use to solid state always being in the future outside of some very small applications.
These are not solid state. Regular li-ion pouch cells more dangerous than LiFePO4.
Output: 4000 Watts Continuous Use (with up to 6000W momentary surge)
Capacity: 2611 Wh (54Ah @ 48V) Question so at 4000 watts this would last about 35-40 minutes???? Back up battery needed for sure. I really like the concept but price and storage is an issue.
True. I don't have a reason to draw that much power for more than a few minutes...if that.
It is rated at 2.6 Wh which is pretty good. You are correct in your math, but common, that is at 4000 watts, which is a LOT.
A 300ah (3.8 kwh) 12v LiFeP04 battery can be had now for 600 bucks. Add a Victron 100/30 Smartsolar charge controller and a 2000w inverter and four 100w solar panels and you have a nice little setup much cheaper that you can repair yourself when the inverter quits. It will last many many years.
I'm waiting for Mr. Fusion to come out so I can power my flying RV with table scraps and flat soda.😊
LoL Hydrogen Fuel Cell Generator!
Hope you're not saving your trash to fuel it :)
I have two Marxon units with total 2880Wh/3600W with a 30amp outlet that I paid about $1200 for. They're going to have to get more competitive with their pricing.
But what’s the cycle life on the Marxon? This probably lasts 8x longer at 4000 cycles.
@@blackrockcity This stations are using standard Li ion cells. All this marketing bullshit about "solid state" is a pure scam. A few bloggers on youtube already disassembled it
Great review Brian! Definitely a first on many fronts here. Solar charging (10a) is a bit limited for my liking but still an impressive unit.
Thanks. Yes. The solar limitation could be better. It works for the portable panels, but not for residential high voltage panels.
I saw minute man prep on UA-cam at CES and told them to fix MPPT to 2000watts.... Then this is a winner.... So i run mini split on garage on a 2000watt inverter power station... Is draws in summer Phoenix heat 900-1200 watts i have 1100watts coming in during day so it keeps up with it.... At night i use EG4 48v to charge on one of the dual mppt and it dies about 3 hrs at night... Battery is still half charged.... But it can only inlut 550 watts but load is 1000 watts so i need to add 2nd battery on othe mppt so it will get the full capacity.... So this yoshino is only 600watts so it will suffer if only solar is charging during the day and load is say 1000watts at end of the day it will not even be fully charged for night..... Like the inverter and power density... Redesign mppt and you will capture the market 😅
I agree. The solar limit is lacking for home backup, but should be fine for 12V portable solar panels. I'm also waiting to see the 240V model which I hoping has a higher solar voltage rating.
60v limit on solar input is a dealbreaker. These units should be able to take a string of at least 3x residential panels, and have a max input voltage of at least 150v. That anemic 60v, 10amp limit, means a single residential panel. Yes, you could Y to 3 panels in parallel, to overpanel, but you'll always be excessively restricted by it's input limits.
At most, this is a battery pack with an inverter/charger. It's not any kind of option for solar use. PASS
Designed more for portable folding solar panels no doubt. My panels on the shop are too big too at around 80V for one. Hopefully they improve this on larger models designed primarily for Home Backup.
It is designed as more of a portable power station, then for a residential I think, 600 Wats for portable is adequate...I like to hear more about the SolidState"nes of this tech besides fire, etc...how about charge/discharge cycles, max charge/discharge, chemistry, etc...
Woah! Solid state batteries are already on the market?!
Pretty exciting to see what's next.
Not actually solid state. I'm wary of the safety claims too. Look up "Will Prowse solid state"!
To be fair, most people aren't going to be sticking a drill in their power station, but if you live in a place with earthquakes, watch out!
No…they are not on the markwet yet. It would appear something is amiss or at least doesn’t add up. So sad really.
@@geraldhenrickson7472what is appearing for you? Tell us.
Highly skeptical that these are solid state considering nobody is making solid state in larger capacities yet.
Capacity (Wh) is King. The Yoshino B4000 has the least capacity vs comparable LFP systems.
@Bonjour-world. All I can say, wait 3 to 5 years from now. Solid- state - battery is no fluke. Its will take significant market share from lithium iron phosphate. Time will tell.
Excellent review. You might have stated it but I missed it, for those that are interested Yoshino claims 4000 life cycles to 80%, not bad. So if it is as safe as LFP, we might have something here due to it's higher energy density chemistry.
It is safer than LFP. Also consider that a single discharge cycle involves fully discharging and recharging. Since we normally don't fully discharge the unit before recharging, then we are extending that 4000 cycle life.
@@RVwithTito when they first release a test version they claimed about 1000 barely 2000 cycles... and no 4000
@@RVwithTito "safer than LFP"...wow, that is incredible. According to Will Prowse you can stick nails into LFP batteries and they will not catch fire. Now we have some competition for LFP which most car companies are just currently switching to.
@@jamescabaniss5857 These solid state batteries are even safer. Yoshino shared some testing video with me chopping the battery with an ax. It didn't flare up, but the LFP did. Pretty cool.
@@RVwithTito VERY COOL!!!!
On some of the output test you clearly got the unit over 4000w but im curious to see how long it will run a 4000w load i noticed you can get some units to their peak out or even just close to it ..but they can only do it for 3 to 6 mins
Thanks Brian. Nice video, great looking portable power supply with solar charging.
I agree. It's pretty nice.
Excellent video! Just a quick note, your Amazon link says 6000 watt bundle, when in fact its the 600 watt bundle. Huge difference, so you may want to fix that. :) Just trying to help. Send me one of those things for being cool and helping, lol. Hugzzz
Oops. Thanks. Fixed it. It couldn't handle 6KW of solar anyway :)
@@RVwithTito I can't wait to put solar in the shuttle bus I just bought. :)
Long Battery Life - 4000+ cycles to 80% capacity This is more than the 3000 cycles for LFP powered options. But LFT can be charged to 100%. Does this have a setting to limit charging to 80%. That limit affects the comparative capacity in everyday use.
Most LFP options these days are good to 5000-6000+ cycles with today's advances in LFP technology. Calendar aging generally becomes a much bigger concern than the cycle life in portable power stations.
@@kuhrd The products this competes with from Ecoflow, for example, list 3000 cycles as their expected lifetime. Those are to 100%.
@@eb1888. Ecoflow Delta Pro 3 states clearly that they rate it to over 4000 full cycles to 80% of original capacity. The cells they are using are rated for far more than that to 80% but they are being very conservative.
Interesting product but you better really need that portability. It costs about what I spent on my two LiFePO4 batteries and multiplus II and while it may weight like 1/3 of what they do it also has 1/3 the capacity. I don't think safety is really a selling factor vs LiFePO4 given its already a very safe chemistry. This stikes me more as a battery that combines power and energy density of lithium ion with the safety and longevity of LiFePO4. Once they get production costs down its a killer battery for ev's.
Too expensive for what it is, but great concept. Thanks
Agree
Thanks for the video. Will this work for the standard size roof AC on my RV? Thanks
It might. You may not even need a soft start. However, you'd probably only be able to run it for a couple hours depending on the ambient temp.
The problem with solid state or solid electrolyte batteries has been longevity. They are claiming 2800 cycles to 80% capacity (which rivals LiFe) but traditionally the expansion and contraction of these batteries during charge/discharge has been a big problem. If it lives up to its claims at a $1 per Wh it's quite reasonable although slightly more expensive than other power stations with similar specs. It's almost exactly the same weight as an Ecoflow Delta Max (2048Wh) so their claims of 25% to 30% lighter are spot on.
A properly cared for LFP power station can easily get 3000 charge cycles before dropping to 80% remaining capacity. So what`s the actual advantage of solid state in the real world? I see none. My LFP power stations have been used heavily for nearly 4 years (I bought the 1st releases) and capacity has remained exactly the same. Even my grade-A lithium ion power stations have had no loss in capacity that I`ve noticed and I cycle them regularly for cooking, lights and frequent power outages. The only minor issue I`ve seen is a loose display cable in my original Golabs R300 bought in December 2020. It doesn`t really affect its usefulness and I can tap it and it clears up. This is a common issue with the originals. It can run my WIFI for 24 hours or cook rice 3 times.
Love the look, color but as one mentioned ..only two 120 outlets ? Also don’t like AC in one end and DC another end. They should have put all in front and charging options in rear. Price??? Kinda high per WH but hopefully will come down like anything else once more manufacturers jump on this platform. Great review
Yeah. All good points. I was on the fence about inputs/outputs on both ends, but now I understand why. Yes. It is the first of its kind.
So its about 200ah for 12v battery
Correct.
Right and the Bluetti LiFePO4 based acl200 which has similar capacity, isn't that much bigger and is considerably cheaper. I cannot see justifying the cost until they come out with the second gen version which hopefully will be even smaller
@@FreynightwalkerPretty sure the AC200L is twice the size of this, and has 'only' a 2400w inverter. And I say that as a Bluetti fanboy.
It does have LiFePO4 too. I know what I want in my house when the Nankai Trough hits again.
Can’t wait until we get more of this. Love that is much lighter than lithium type.
Good demo. You explained well.
Thanks!
Interesting power station.
I am waiting on the new 220 v model that was at CES
I'm hoping to test those too when they come out...Stay tuned.
Thanks for the video.
You bet!
Couple quick thoughts. I wonder what the DC amp output is on the front DC5521 ports, and WHY did they not write in on the power station? The solar is limited to 10 amps? That is WAY too low. For me personally, I have to have all my ports in the front, but I guess for some people having some on the back would work. While I doubt this is safer than LiFePO4 battery chemistry, at 51 pounds for 2.6 Wh it does seem to have a LOT more energy density making it a lighter unit, nice. I wonder what the life cycle is, I hope it is at least close to LiFePO4's 2000 to 5000 times.
did it turn your transfer switch on? some power stations spool up the power, so the transfer switch does not see 30 amp... wondering how this did?
Thanks for not calling it a ‘Solar generator’. Absurd marketing moniker that ranks up there with jumbo shrimp.
😃
What's wrong calling it a Solar generator ? A gasoline generator uses gasoline to produce power . A solar generator uses solar to produce and store power 😢
A “gas generator” converts chemical energy to electrical power. A “solar generator” converts solar energy to electrical power. Simple.
This doesn’t generate. It’s a battery. It stores the energy.
@@ChachinRClook up definition of generator. And while you at it “accumulator”
Awesome kit. Hope Bluetti gets something similar next gen solar generators.
This one looks to nice to put into work 😅
They are not solid state batteries. They catch fire the same way the other lithium iron batteries do. Sad that they lied about that important issue.
I reached out to Yoshino for comment on this. They responded promptly. I shared their response in a pinned comment as well as in the video description. Hope it helps.
I'm new to solar & power stations, planning to buy the B4000 to use as my primary energy source for my tiny home which has 1640W solar panels but noticed the B4000 max solar input is 600W. I know I need a charge controller but getting confused on which to buy and what to do with it, does anyone have any ideas?
Also not sure if its internal mppt charge controller is sufficient in handling 1640W solar panels
If you primarily plan to charge by solar, the 60V, 10A, 600W max PV input is pretty limiting for larger solar arrays. The the voltage limitation alone won't support a lot of residential solar panels (including mine). This is primarily designed for portable power and portable solar panels. Here's my setup (ua-cam.com/video/XQtjPs7Jg_o/v-deo.htmlsi=j2eyBn5UUvs0Rbe_) It's more effort to setup, but you could get a less expensive an all-ink-one solar inverter and LiFePO4 battery combo to accommodate your 1640W of solar and power your tiny home. Yoshino is releasing a larger unit in the near future which may be a better fit if you're set on this technology. Hope that helps.
"POWER STATION " is the right way to describe device like this, I hate the usual thing people are referring to as "Solar Generator"...What a great Review Tito 👍👍🤗🤗
A “gas generator” converts chemical energy to electrical power. A “solar generator” converts solar energy to electrical power. Simple.
This doesn’t generate. It’s a battery. It stores the energy.
Simple. Not a generator.
This thing can generate power indefinitely with its battery untouched at 100% while you continue to supply "solar fuel" to it. Trust me, I've generated power this way with my Bluettis for hours on end. You could call it a solar generator with a battery. As long as you have solar coming into it, its battery is irrelevant. Nothing wrong with "Power Station"; it does that too.
Solar generator uses solar. Gas generator uses gas. One is on-site energy going forward. The other continues to cost money and requires trips to a gas station, oil changes, spark plugs, repair, cleaning the fuel system, replacement of lines, etc.
@@jmorrison5206 The circuitry bypasses the battery at full charge when running a device that uses less power than the solar input. In fact, 12v DC devices like cookers/fans/lights can easily use straight panel power generation. The battery only switches on under this condition when a cloud passes over...similar to a capacitor in a circuit. Solar is on-site power and over time is far more efficient and less expensive to use than a gas generator. I would never want to power my freezer with expensive gas after a hurricane. A gallon of gas, if I store the energy in a battery, can run my freezer for a week instead of only 3 or 4 hours. So can 6 hours of solar charging.
I’m interested thanks Brian 😊
You bet! I've enjoyed using this power station and plan to take it along on our next RV adventure. I'm excited to see what else comes out of this company.
I could easily run this to a 12v fuse block and run my whole rig! 😊
why is there a problem with the term solar generator?
The term is inaccurate on the face of it. A generator is something that makes power on demand and can keep on making power as long as you add fuel. "Solar Generators" are just battery banks that last until they're discharged, and it takes a significant amount of time to recharge them - especially if you're only using solar power. Very misleading moniker for them, I've always thought.
I know ,right
There is no problem. A “gas generator” converts chemical energy to electrical power. A “solar generator” converts solar energy to electrical power. That’s it.
Generator converts mechanical energy into electricity. Solid state methods of creating power have their own names like solar cell, fuel cell, etc. It's blatantly wrong terminology used for marketing purposes.
Do you know where to buy the add on expansion batteries?
They won't be released for another month or so I've heard.
Hello Brian, nice video but I'm more interested in the technology and history of the solid state battery.. as you know they have been promising this technology for years and I'm surprised to see something that is actually using it.
Welding, ha that's great.
Good video. That said, would love to see a head to head comparison between the SS & the Ecoflow Delta Pro!
Nice video and review. Is it a large capacitor since it is called solid state?
I made my annual pilgrimage to the Kitsap Peninsula to fix and upgrade my RV. I have a long list to keep me busy for a couple months. 😂😂
No, it’s allegedly using solid state cells. It’s not a supercapacitor.
Audiophiles like to use the cleanest power possible for their equipment. I wondered whether the Power Station outputs power much cleaner than a typical power outlet in an apartment building? How do you evaluate this aspect of its performance?
Professor Hobo tests solar power stations with a guitar amp plugged into them for RF interference. My new home has terrible RF interference and I love listening to very long range shortwave radio signals. Now I can only do that during power outages. Even regular AM radios get exceptional (daytime is very surprising) range after hurricanes knock out everything. That`s why I promote high quality SW & AM receivers for these emergencies to get info when cell phone, radio and local TV signals are gone after these storms. Few care though. That`s why I was the only one with very important info in my area after hurricane Laura.
this is the future!
It's a good step forward now that we all have 10 yr LFP batteries 😃
Can you use this batery like a hole house back up? For ligths of the entire house for example.
Maybe if you pile a few of them, can you do that?
I'd wait for the larger 240V split-phase unit for that. It's coming.
Very cool power station great review thanks Brian
Thanks for watching!
Coldest operating temperature?
O°F according to Google.
Perhaps. I couldn't test that since it's 90 degrees right now 😀
@@RVwithTito 😂😂
We need to judge it on multiple points
- As comparable solar generators go, its performance is behind leading brands.
- the price is high.
- the advantages of the solid state battery are minimal compared to similar standard devices.
They tried. Maybe their next model will be more competitive
They're talking about a 6000w unit with 4kwh onboard and unlimited potential for daisy-chained 2kwh extra batteries. I'm interested, but we'll see...
@TheCornucopiaProject-bd5jk yes for the price it's competing against Anker f3800 or delta pro 3 which are more capable or comparable to gas generators imho
There always has to be a first version for any new tech. Solid state is in it's infancy and has massive potential advantages over other chemistries. Don't be so quit to write it off.
@@meikgeik I did not write the tech off. I simply said this model is not competitive enough. The “stand out feature” simply does not stand out here.
needs more sockets and all located on one side
It looks like the Vespa of power stations.
Always enjoy your videos. Can’t see this as an alternative to say the Ecoflow Delta 2 Max for far less than half the cost unless you really need 30amp capability.
Maybe that's why Yoshino uses solid-state lithium batteries-they perform better than LFP, which is pretty rare. I'll definitely give it a try when they have a good deal.🤣
@@liyaliao4299 You will have a while to wait… at double the price with not much more capability (wH) why? I admit I’m a sucker and spend much more than the average bear for new tech but what are you really getting for the crazy price. Have you compared any of the popular 2kW units (Anker, Bluetti, or Ecoflow to this one?
@@dragonseggs thx for your suggestion, I looked at delta 2 max, Bluetti AC200 max, they all have good functions, but I still worry about the safety of 2kwh battery, as I usually use a battery connected to my CPAP at night when I sleep...
a 240v version would be awesome, any in the works??
Yes. I hope to test one. The expansion battery will be released next month and I'll test that out too. 👍
@@RVwithTito sounds good i hope its 240v like direct, like the new ecoflow delto pro 3
Hi Brian. I appreciate your all your vids. Do you think this would run one RV a/c unit and if so, for how long? In the middle of a heat wave. Right now even with 900 ah of lithium I need run our generator to run a/c. Since most parks have generator hours, it would be nice to have an alternate source if we are hunkered down inside and not able to use our generator. Thanks in advance! Ron
I will probably run one A/C but only for about 2 hours.
Thank you, Brian. I will be installing a couple of soft starts first. That should help. Again appreciate all your posts. I have followed several to a T and those worked perfectly!
@ronnaldpopp2282 running 900ah I'm assuming at 12v gives you roughly 12kW of potential energy. This unit is roughly a third of your current battery 🔋 storage . Look into 3or 4 server rack batteries and upgrade your system to 48v.
I don't need such power right now .. but I think it is a great review. If it can go on line, can it be controlled via the internet?
Yes. If WiFi is enabled you could control it remotely from the app. It also supports Bluetooth.
How many watts solar panel
do you need to charge Yoshino?
2 important questions,at least to me, how long does it take to charge through 12v ( cigarette lighter socke) and what about cold weather. If your vehicle go cold below freezing will it operate or damage the batteries?
Well since cig lighter ports are limited to 100 watts approx., and this is 2600 Wh, it should take about 26+ hours to charge. Per the description, Charging Temperature 32 to 104°F / 0 to 40°C and Discharging Temperature 14 to 104°F / -10 to 40°C
Maybe I missed it but what is the cycle life?
4000
Wish this was available in India right now.
And how do you power a whole house with stack of these?
I'd hold out for the 240V split phase unit.
Imagine the cost!!! who can afford this?
It looks like to me this is not UL listed. The description says "ETL certified to UL2743 standards" which is NOT the same thing, and when I go on the UL site i can find nothing on this unit. If it was UL listed I would have LOVED to see the sticker on the unit that says this. I have purchased many power stations that state they are UL listed, but so far unfortunately they all were not. They just say they are, or they just say they 'conform' to UL standards. The best i have seen so far is that the external charger is UL listed, (i.e. "the brick" or AC adaptor) which means little to me.
Waiting for this technology to become cheaper.
*Question* sooo... can you discharge it to 0% like lithium or just 50% like AGMs? Does it hold a charge like lithium, or does it slowly discharge like AGMs? Is temperature a factor like lithium in cold weather? Great video...wish I understood more about electricity.
It's not like lead acid. It's lithium based. So you can fully drain it and recharge it again.
@@RVwithTito that's great..thanks!
The '60's want their paint scheme back.
I think it looks great.
it's a combination of every shit#y color known.
Can I hook it up to my car’s battery for charging by the alternator?
It comes with car charging adapter for charging while driving. It has a 10A max.
Direct to battery through separately terminated pos and neg lines (which bypasses OEM fuse box) or through the integrated “cigarette lighter” port (which goes through the stock fuse box)?
Good review, but the claim of solid state is something I question. The advertising DOES say it's solid state, but it also says it's an enhanced lithium chemistry. I don't know of any truly solid state lithium storage under development, but maybe they are referring to a solid state inverter or some such. I don't believe that this is well-constructed or engineered, but you should certainly feel a solid state battery - much lighter.
They're really "semi solid state", there's some gel-like electrolyte in there too. The cells themselves are flat sheets, which is why more can be packed in to a small unit.
Last year I saw power stations claiming to be semi-solid-state with 50% solid electrolyte. So I asked Yoshino: Are these cells semi-solid state? They answered: Our solid-state batteries consist of 95% pure solid electrolytes and 5% liquid catalysts. Hope that helps.
@mikebrand192 there are a lot of solid state batteries under development currently. There's a handful of companies doing production line scaling right now. Toyota is testing it's production lines and said they'll have solid state in Hybrid cars for next year's models. It's possible these units are being made with early test runs off of one of those companies. Could even be early Toyota B grade cells, to my knowledge no one has done a teardown of these yet. I've seen other "solid state" cells in other videos, and they're just very rigid gel cells that are still highly flammable.
@@meikgeikThey also shared some puncture and destructive test video with me showing that they didn't flame up when chopped with an ax or punctured. The NMC and LFP cells did.
@@meikgeik Excellent news! I was losing hope, yet again. BTW, Sabine Hossenfelder has a new UA-cam on battery tech and The Hype Cycle. ua-cam.com/video/2eIPHX-NpMM/v-deo.html
What’s the level of water & weather protection?
eh it's 54ah at 48v. a last-gen LiTime or Chins is better than that, albeit lacking the shiny case and ports.
Why do you get the power station blocked
Could you elaborate on the solid state batteries? What are they, LiPo4 or what? Lifetime of these devices varies, had a neighbor who’s LiIon camp chargers batteries had to be replaced every 3-4 years with regular use as battery level dropped to 50% after 500 cycles.
They're supposed to be more long-lived than the "old" (still used in every phone and tablet) NMC, but not as good as the "new" (to solar generators, but the underlying tech is a decade older) LIPO. But they're still lightweight and compact, so everything's a tradeoff.
@@michaelmartin9022 - So essentially they are LiPo4 batteries then?
@@Erin-Thor No, something different, but I'm not sure what. LIPO have poor energy density so are always big and heavy. These solid state ones seem to be some sort of new "in between" option as far as lifespan goes.
Or, at least, as far as the marketing department's claimed lifespan goes.
@@michaelmartin9022 - Thanks, looking at their website now for more info.
I'm interested to know how a mid/highend desktop computer with active load would handle the UPS 20ms switch, would the computer shutdown?
Did some digging on my own. The ATX spec supports a powerloss up to 17ms but PSU manufacturer could still improve upon those specs. UPS designed for desktop machines are capable of doing this switch in 10ms. Compared to those the Power Station is slow in that specific usecase.
Yeah. 10ms sounds like the benchmark I've typically heard. Honestly, I don't have an answer since I primarily use a laptop...also on a UPS.
weight vs regular lithium ion
I own the B4000 SST used it for the first time last month in July, the unit did work fine, but after watching this, and the other video that surfaced where they lie about using solid state batteries, I feel cheated. Is anybody starting a class action suit or something along that line to hold them accountable for false advertisement?
Is it have uk plug?
Perhaps, needs an update that they are not 100% Solid State
I reached out to Yoshino for comment on this. They responded promptly. I shared their response in a pinned comment as well as in the video description. Hope it helps.
@@RVwithTito actual testing and teardowns place it more of a '" SEMI SOLID STATE " battery.
Does it come in camo?
Does it do 240VAC natively? With a 50 amp plug?
This one is 120VAC single-phase. There's a 240V split-phase coming soon I hear.
How long (years) are solid state batteries rated for in this unit?
My understanding is that the batteries will outlast the electronics that control them. Somewhere past 10 years.
Thank. You. The tech. Information. From. The. Comments on. Cost savings. Is pure gold look. At. The Comments are. We're. The. Real info. Is. Thanks
Rich for my bones
Maybe i missed something but this just seemed like a marginally smaller ecoflow to me
What if this unit is exposed to a fire?
expensive for a 2 20 amp outlets.???
Should just call these battery inverters with ac outlets. -a “BIAC”
This was the best video I seen of this unit yet. The only thing I would have liked to see is if it will charge by AC and solar simultaneously.
What about AMP out put and imput
Uh, lookup Li-NMC batteries, which this unit uses. Off-gassing and thermal runaway. It has a little greater density of energy storage over LiFePhos chemistry, but the latter is safer and has a larger rated number of charge cycle, which means that LiFePhos will generally last longer. I don't see this unit as a good option.
Good to know, thanks
That's a really thorough review! Well done.
How long might it run a refrigerator?
You should have mentioned the battery cycle being 4000 and 5 year warranty. This being a new technology not enough info plus high price tag.
Saw the price below your post. Waaaayyy to rich for my blood. Stay safe and vigilant.
All of that additional info is in the video description.
Common sense for any gen 1 product. There's a point when the individual has to take some responsibility.
Question can you charge it with solar power?
Yes.
I've had 2 of these fail on me after 2 months of use.
What happened?
Tito, who has the money to buy all of these toys. Who has the room in their rig to haul all of this stuff?
Solid State does not like anything except a smooth, perfect current. It doesn't like voltage fluctuations at all.
A very well thought through testing video. Do you know if they are making a version for the UK market? One with uk plug sockets. Many Thanks
@0:27 "...all those issues.." Gotta love all the detail in that description. Do you even know what 'those issues' are?
We really need a new battery standard, especially for ev's, hopefully solid state batteries will come out at some point
4 hours of space heater. Really points out how bad source heaters are.
What does it cost ???
This fake costs about $100 more than other fake solid state packs out of China. The extra money pays for youtube influencers shilling for it. It's been torn down. It's not solid state. Just marketing and a markup to pay for online promotions.
