Absolutely incredible!! The JUNOJUMPR looks like an ordinary external battery, but this special device carries an extraordinary 6,000 mAh – that’s powerful enough to charge a completely dead CAR BATTERY! Wow! The kit comes in a cool-looking, matte black box and includes the battery, jumper cables, car adapter cable, and USB cable. The JUNOJUMPR is only slightly bigger than an iPhone, weighs 7 oz, and besides charging a car, can charge smartphones, cameras, and tablets. The battery charges in about 2 hours and can hold the charge for 6-12 months. An amazing product to keep you charged for all your TrailblazerGirl adventures!
