The Avid Power 4000A is a combined lithium jump starter, tire inflator and power bank. Its 4000A peak rating and 27,800mAh battery are aimed at large gas and diesel engines, and Avid Power claims up to 60 jumps per charge. The built-in 150 PSI inflator and 600-lumen LED make it a roadside tool for trucks, SUVs and vans. Against dedicated jump packs it trades a little peak output for the inflator and air compressor built in.
