    Customers are mixed about the battery life of the jump starter. Some mention that it is light, clean, holds charge for a long time, and can be left in the car. It will last for multiple jump starts on a single charge, and it can charge your phone and jump your car battery. However, others say that their car sits for 2-3 days and the battery is 100% dead. The battery itself only lasts a few weeks before it needs to be recharged, and dead batteries are never planned and always occur when least expected.
