Any one have experience with these?
Maybe 120,000mAh? 444wh÷3.7v=120ah.
I saw some online showing 120,000mAh, so gotta wonder if these have less battery (5 of 6 x 20ah packs removed/missing, and they didn't change the wh spec)?
The 500w AC inverter is likely square wave, which I wouldn't use for much aside from an old school filament bulb.
Personally, I'd probably go for one of those car booster packs that also have 5v usb ports. Smaller, and might start the car if need be ;-)
