How many times have you had to ask a friend or a stranger to jump your car after its battery dies With the Mighty Jump Pro, you don't have to worry when you accidentally leave your headlights on overnight or your radio running for too long. This conveniently compact emergency jump-starter allows you to jump-start a vehicle without leaving the driver's seat, making it great for safely activating dead batteries in winter weather or deserted highways. This new model is designed for a super-quick battery charge of only ten minutes so you can efficiently get to where you're going. The battery is also rechargeable for multiple uses. When the Mighty Jump is plugged into the dashboard cigarette lighter (DC socket) it transfers power from itself to the car battery, using the internal wiring of the vehicle. This battery is perfect for 4, 6 or 8 cylinder gas powered cars, light trucks and SUVs that use a 12 volt electrical system.
