The jump starter works great, is innovative, and charges quick. My wife and I purchased the jumper in case our battery ever needs a jump start. The usb, power adapter, and jumper cables fits nice and snug. There is no wiggling or loosening. The device has a power level indicator and emergency light assistance. It comes with compass that work well. The jumper cables open easily and hold tight. Overall, this is a great portable jumper cable with a lot of features.
