so far, everything seems to work. Arrived with 91% charge. I plugged into a K-box 48q cooler, which was drawing about 60w and after an hour it was down to 71%, which I think is what I would have expected if I'm looking at the math right. I don't think the cooler is very efficient, so I'm hoping a more robust cooler that is has a temperature setting (and does not run 24/7) might be able to get a bit more out of this.
My goal, hope is to use this with a solar input to have it run a cooler for camping over a 3-4 day period. i'm so tired of ice runs....
I'm hoping a 100w Solar panel should be able to keep this going on a daily basis. (fingers crossed). I don't have a panel yet, so can't test that part just yet.
but the unit I received appears to be working fine so far. Wireless connections on top seem to top out at 10w (I was hoping 15w, but oh well).
display on the unit is pretty straight forward and seems to work fine.
The one slight con I see so far is that the on/off buttons themselves seem a bit weak (like maybe they won't last), but I'll just have to wait and see.
hope that helps others.

also, I went ahead and recharged from 70% to full. took 2 hours just to charge up that additional 30% on A/C. it was pretty consistent at about 15% capacity increase per hour on the A/C charge cords. That is a bit slower than I expected, but I'm not sure what to expect. that seems to suggest it would take a good 6+ hours to fully charge from zero. When I do eventually charge from zero to full, if I see it's different, and I'll post back.

I'll contact their customer service option, but I suspect I will be returning it. If I'm having problems on day 2, then I do not have a lot of confidence in this unit working long term...
too bad. was a good price for the capacity, and I liked the overall design.
Posting this now in case it gives someone any help in their decision on whether to get it. I will post another reply after I resolve or return with feedback on their CS process.

So my unit (the 346wh), after having some issues getting it to come back on after fully charging, 'seems' to be working correctly now. Hoping it stays working. I do like the size, design, and price - but only if it's working.
regarding the charging speed; it's a bit weird. The unit says it's charging at 110-120w from AC when it's charging (which is what the manual suggests is the max AC rate [120w], but it sure seemed like it was charging at more like the 78w rate that was originally printed in the manual before a 'sticker' was placed over the product specs. The sticker specs say 120w max AC. The sticker also says '518wh' for total energy; which I don't think is right based on my early testing. I do think it's only 346wh which is what is says in other spots in the manual, and is what I was expecting. The manual is just full of inconsistent info, probably because they use the same manual for multiple models.
18W LED light strip running direct off DC power. Ran for 28 hours and still did not shut off the unit.
28hrs X 18 Watt = 504 WH (over their stated capacity)
Wattage at Cigarette light plug showed 11.03 Volts, and i'm guessing BMS shut off would be in the high 10's so i stopped the test there to alleviate undo stress on the cells.

Ideally the unit should cutoff at 12v, else internal charger cannot charge and battery will be damaged permanently at 10V or lower if left uncharged for too long.

Quite impressed with the overall WH of it so far, but also did try and run my 600W induction cooktop and the unit would power off and not run it... so i think the 630W output might be a little less. I will have to test with some other 600W items in the future
