The Suaoki U10 Jump Starter is innovative and charges quickly. My wife and I purchased the jumper box, just in case our battery ever needs a jump start. The usb, power adapter, and jumper cables fits nice and snug. The device has a power level indicator and emergency light assistance. It also has a nice compass that work well. The jumper cables open easily and clamps tight. Overall, this is a great portable jumper cable with a lot of great features.
