Cobra JumPack XL Heavy Duty Jump Starter & Power Pack

Got this Cobra JumPack XL heavy duty jump starter and power pack. It's got 500A peak current and a 41.1Wh battery capacity, so it can jump start full-size trucks and stuff. Also has a USB port for charging your phone and a built-in LED flashlight. Box is a little worn but the unit inside looks good. Handy thing to keep in the trunk just in case.
