So much more than a jumpstarter. Sure, it has self-contained jumper leads and a huge 17Ah battery, so itll bail you out of many situations. But the real utility of this unit comes from the additional features. Theres a built-in air compressor to inflate tyres. Theres a 5-LED high power work light on the front so you can see what youre doing. 2 x cigarette lighter sockets as well as 2 x USB sockets for powering and recharging many devices. An internal battery condition gauge helps you make sure its ready for action, and its all in a self-contained unit!
