I have a craftsman jumper box with:
air compressor ( yes, it takes forever and the pressure gauge on back is not correct)
2-AC outlets ( works as an inverter )
2-12v DC outlets (auto cigarette lighter type)
Blower ( for inflating tubes or sleeping mattress)
USB Charging port
and it will jump start my truck
this has worked fine, my only complaint is the air compressor, but it will get you out of a jam.
I have had to use it in house, to charge phones during power outages.
Better than having to go out to your car to charge.
Mine looks different - older model -?
