How large of a jump pack is really needed for say a V6 engine? And what kind of heat can things take? I live in the deep south and the car Interior So

I bought the Audew jump pack 3 years ago and have jumped cars and motorcycles with it several times. Lives in my truck or motorcycle year round. Small enough with enough power.
Plus you can charge phones or lap tops with it.
