Amidst the never-ending phone accessories at CES, this one stood out: A portable battery that can charge your phone AND jumpstart your car. The PowerAll is a rechargeable 12000-mAh battery with two USB ports (it holds roughly six charges for a smartphone) and a built-in 86-lumen LED flashlight.

The sell, of course, is that it’s also a 400-amp engine starter, which can jump-start your car’s battery up to 20 times on a full charge. It will keep its charge for three to six months, so it is crucial to remember to check its status every season or so, but since it can help you out in several situations and is only about double the weight of a smartphone, it seems worthy of a place in the trunk.
