Nothing can stop a field service tech in his tracks like a dead battery. Not only can it kill a smartphone or tablet, it can also inhibit a vehicle, halting any semblance of progress during a day’s work.

However, this year at CES, a handy little device was introduced that can reportedly get field techs up and running in no time. The PowerAll, a 12000-mAh battery that is roughly the size of a smartphone (double the weight), can charge a phone and jumpstart a car. The charger also comes with two USB ports and a built-in LED flashlight. Priced at $100, the charger is a 400-amp engine starter and boasts 20 car battery jump-starts and about six charges for a smartphone before it needs to be recharged.
