it weighs about 17 pounds about the same as the other jump starter they sell, the ones rated at 1000 amps have a 19 ah agm battery in them. But it doesnt say that anywhere, a review said it had a 17 ah. If its 19 ah thats about 9.5 ah of usable power.
A roadpro food warmer uses about 11 amps an hour ( but it only takes maybe 20 minutes to heat up a can of food. It can easily charge cellphones etc or power small fans. But this unit doesnt have a 12 volt receptacle to connect the roadpro.
No easy way to connect solar to it, though the agm battery inside can easily handle being hooked up to solar. I've connected similar jumpstarter agm (17 ah) batteries directly to my mppt/240 watt solar panel. They can easily handle being charge by high amps and the battery actually prefers that over being trickle charge. On my jumpstarters I actually opened them up and connected wires directly to the battery so I can charge them off solar, but requires some skill to do it.
But that is better than waiting 10 plus hours to trickle charge it.
To even consider to use it, it need to be fully charge, like the day before. I notice these type of jumpstarter packs don't hold charge well for to long. If not charge regularly they lose capacity very quickly. But for 70 dollars it might have its uses to jumpstart a dead battery or charge cellphones.
The other stanley upright 1000 amp jumpstarters do have a 12 volt plug, you can connect the roadpro.
