    This little things pretty nice but the manufacturer doesn't seem to give some vital information about it. Their website says they have a BMS which is great but doesn't specify what Battery Management System they're using. Seeing as it's winter I was curious if it had Cold temp shutoff as charging below freeing is bad but see no info anywhere about this. The included charger for the unit isn't the full 100w that it supports over power delivery and it utilizes the barrel plug to do so. I have multuple PD 100w USB chargers, in my testing it will take the full 100w over PD but it will shut down after about a minute or two then turn back on, over and over. They sell a 100w solar panel but the manual says it only supports 80w solar. This might be why it's shutting down over PD and why the included charger is less wattage. It could be getting too hot and turning off for a bit which I suppose is a good thing but that info would've been nice to have. It also doesn't say what type of charge controller the solar charger uses PWM or MPTT, this usually means it uses the worse/cheaper of the two PWM which isn't as efficient and usually charges slower. I'm glad they specify the inverter is a pure sine wave but that makes sense since it's more expensive and better than a modified sine wave inverter as they work better with electric motors. The flash light has an S.O.S flash mode which actually flashes S.O.S. unlike some of the others I've tested from Anker which flash S.O.S. O.S.O. I'm giving it 2 stars out of 5 simply because many people are rating it 5 stars without knowing what they're talking about, artificially inflating it's star rating. Normally I'd give it 3. This is a pretty good value for around $200 many of these all-in-one units don't have the best of everything but they're convenient because of their small form factor as oppose to building your own.

    Bought this to take camping. It would not run a small floor heater or the small coffee maker. It would only work to charge cellphones and a small light. Disappointed in this purchase.
