It is the first product of its kind that can transfer power directly to the car battery through your vehicle's power outlet. Equipped with Smart Charge Technology, not only can it recharge devices like smartphones, tablets, and gaming devices, it also has enough power to jump-start a vehicle - all from the security and convenience of the driver's seat. Recharging the Pocket Jump is easy using the included USB cord. You can charge it in your home or car using your block charger (not included) or USB car plug (not included). Power indicator LEDs let you know how much of a charge you have before you leave home.
