Yoshino B660 - World's FIRST Solid State Portable Power Station 

Plus they cost less.

I'm actually working on it. Stay-tuned!

It stays stable for much much longer, for many years you can keep recharging with low battery degradation and it doesnt Explode when it gets old and the dendrites grow out of control and puncture the battery

I'd be extremely surprised if they aren't using SS cells - surely SOMEONE would have made a very public revelation of that fact...and I actually DID search before I accepted the invitation to review the unit, because I had the same concern. Came up with nothing. And they didn't just start shipping this product line super recently. They've been on the market since well into last year. In any case, I may have to see if I can non-destructively (or not) get into it and see for myself. I'll certainly report back if I find anything worth reporting.

@@ReeWrayOutdoors They are likely ether condensed matter (aka gel electrolyte) CATL cells, or generic LiFePO4. Or even worse, NMC. Someone would have to tear the thing apart to get a charging profile for the BMS+cell pack with all the other power electronics out of the loop, read off cell IDs, and even potentially tear apart a cell (which can be rather dangerous to do which is why cell tear-downs are not done by enthusiast youtube reviewer channels. Only by actual chemists or actual battery EEs). In anycase, nothing about the company makes any sense. Their web pages are static and don't seem to get updated, they are pairing bottom-of-barrel-cheap power electronics with supposedly high-end battery cells, unit weights don't imply a high power density. Very limited current caps. Nothing makes sense. None of this points to the use of actual solid-state cells. It's probably marketing nonsense. And even if they were, the units are no better on any metric than LiFePO4 would be. Nobody should be wasting their money paying a premium for this brand. -Matt

Not a scam, though it performs almost exactly the same as semi-solid batteries which have been around for about a year or so.

Which one did you have? I been thinking about getting one.

Maybe not the definitive destruction test you envisioned but all I could find with a quick query.

@@ReeWrayOutdoors seems like an expected result, just don’t know if that is the same battery, maybe if the tested battery was compared to one from a tear down and confirmed to be the same. That being said I understand not wanting to destroy a nice piece of tech you have been gifted with or purchased yourself. Guess we will have to wait for a test from JerryRigEverything. He seems to really like tearing things up.

Solid state production capacity just isn't at the levels to produce for EV and mobile devices yet. Hell, they can't even produce enough to keep these power banks in stock. Been a few weeks since prime days sale and the 330 is still unavailable. The price that SS is currently at would be a prohibitive factor for those applications at this point too. It's definitely coming, but mass market on that scale is still years away unfortunately.

Yeah you'd think. But for whatever reason, my test setup almost always nets more usable capacity on the AC side. It's very consistent across nearly all of the units I've tested.

@@ReeWrayOutdoors I get ya, I'm not questioning your test bed or ability, just a little strange to me. Thanks for the videos BTW

They use a dc to dc converter on the dc and it looks like it's less efficient than the ac side

@@clevernduruza8624 why dc to dc? Unless they have to down volt it

​@@scotth9984DC voltage reduction or increment will always be necessary. Even USB loads demanding the same power might need different voltages. E.g a 20W load might be 2A, 10V or 1.67, 12V.

Oh nice idea on the red light! I just started dabbling in astrophotography. Got a 10" Dobs for visual and just using a Star Explorer GTI and mirrorless camera for photo

It's their small unit. It's capable of charging much faster. It's just capped to try and make you buy one of their extremely overpriced larger models.

Me too, and the weight difference for the equivalent of my Dabb to what they claim is... A truly SS power station? Marginal, at best... This is just marketing hype I think...

The limits are basically just low-balling the design. The cells themselves (no matter the chemistry) are not that severely limited. And I seriously doubt the battery cells are actually solid state in the first place. Insofar as the AC brick goes... when power stations first came onto the market having an external brick was fairly common, but those bricks are annoying as heck once you've collected a few (I have at least a hundred in my pile now, over the years). Most people far, far prefer just plugging a standard computer AC cable directly into the unit. I got piles of those too, but at least computer power cables are all interchangeable. There isn't really anything that can burn-up with an internal AC adapter. It is literally just a transformer, rectifier, and a capacitor. Like three parts. Ok, four if we include the internal safety fuse. AC bricks are basically used in designs to avoid having to have UL AC testing done on the unit as a whole. The brick is purchased with all the certifications already done. Useful for quick-and-dirty designs but annoying otherwise. -Matt

@@junkerzn7312 A brick would not deter me either way. However, not having reasonable solar input pretty much just makes the unit in the video a really super small battery that you can't even charge. I have several units as well but they have to be rechargeable to be truly useful. Thank you for the info. on the bricks good stuff!

I thought that was pretty funny though…

Don’t be so angry !!!
