Always be prepared for those situations where you need power! First of its kind, the ViaTek Pocket Jump is small enough to fit in your purse or pocket yet powerful enough to jump start your vehicle and charge any electronic device via USB cord. Always be prepared to make that emergency phone call or have that ablity to safely jump you vehicle off without ever having to worry if the 'right person' will come along to help. Best part is that you can do it all from the driver's seat of your vehicle never having to step outside. This device can transfer energy directly to your dead battery via the vehicle's power outlet. Since it has the power to jump start a vehicle it also doubles as a power bank able to charge any electronic via USB cord in half the time.
