Having a dead car battery sucks. But fear not! You no longer have to fumble with grimy jumper cables or flag someone down to get your car back on the road. Mighty Jump PRO [$35] is an emergency jump-starter that allows you to jump-start a vehicle without leaving the driver’s seat. When the Mighty Jump is plugged into the dashboard cigarette lighter it transfers power from itself to the car battery, using the internal wiring of the vehicle. It only takes 10-15 minutes to jump off your car and then the Mighty Jump will store easily in your glove compartment, cup holder or trunk. Easy-to-follow directions are printed right on the unit.
