(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.

[@RVingwithBandit]

WOW!!! I was just going to ask if you saw any of those destructive tear downs of this battery.

[@LarryRichelli]

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!

[@vladimus9749]

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.

[@tylersutton2216]

This is true it's not actually solid state

[@RVwithTito]

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 KZbinr 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.

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.

[@geraldhenrickson7472]

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.

[@mondotv4216]

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.

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 😅

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.

[@RVwithTito]

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.

[@mgkleym]

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.

[@eb1888.]

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.

[@kuhrd]

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.

[@jamescabaniss5857]

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?

[@my_channel_44]

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

[@RVwithTito]

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.

[@georgedemean2228]

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...

[@GymWithRay]

Do you know where to buy the add on expansion batteries?

[@RVwithTito]

They won't be released for another month or so I've heard.

[@mondotv4216]

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.

[@baneverything5580]

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.

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 (kzbin.info/www/bejne/joLXm4OpbK-aldEsi=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.

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.

[@vladimus9749]

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.

[@ChachinRC]

A “gas generator” converts chemical energy to electrical power. A “solar generator” converts solar energy to electrical power. Simple.

[@jmorrison5206]

This doesn’t generate. It’s a battery. It stores the energy. Simple. Not a generator.

[@ChachinRC]

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.

[@baneverything5580]

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.

[@baneverything5580]

@@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.

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

[@TheCornucopiaProject-bd5jk]

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

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.

[@Erin-Thor]

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.

[@michaelmartin9022]

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.

[@Erin-Thor]

@@michaelmartin9022 - So essentially they are LiPo4 batteries then?

[@michaelmartin9022]

@@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.

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.

[@RVwithTito]

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.

[@mikebrant192]

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.

[@michaelmartin9022]

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.

[@RVwithTito]

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.

[@meikgeik]

@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.
