The Crankbox is a glovebox-sized jump starter and tire inflator in one unit. It clamps onto a car battery with reverse-polarity protection, inflates tires to a set pressure and stops on its own, and doubles as an 8,000 mAh USB-C power bank with a built-in light. It suits drivers who want one compact tool for a dead battery or a soft tire instead of separate jumper cables and a pump. Against dedicated jump starters it trades cranking capacity for the inflator, and it is not built for large diesel trucks.

The Crankbox is a jump starter and tire inflator in one compact unit. It starts most cars, crossovers and SUVs. It is not made for big diesel trucks.
To jump start a vehicle, clamp on, press one button and start the car. The clamps have reverse-connection protection, so nothing happens if they are hooked up wrong.
As an inflator, it fills tires up to 150 PSI. Set the target number on the screen and press start. It stops on its own. A car tire goes from 29 to 36 PSI in about a minute. It also works on bike tires, balls and air beds.
