Weego JS6 Jump Starter Standard Battery

Why carry around jumper cables when a smartphone-sized device can handle the job? The Weego JS6 Jump Starter Standard Battery does just that with its 6,000mAh rechargeable li-ion battery, boosting gasoline engines of up to 4.6L (or diesels of up to 2.4L). The pack only loses about 2% of its charge per month in storage and includes an LED flashlight for fiddling around in the dark. It’ll also jump start your phone or tablet thanks to its USB port, making the pack useful even if your car battery is perfectly healthy.
