A jump pack is a small, battery-powered device you can keep in your car. When the main battery dies, it gives a quick burst of power to start the engine.

A jump pack is a portable battery system that provides enough power to start a vehicle’s engine when the main battery is dead. It typically contains a rechargeable battery, an inverter, and cables to connect to the car’s starter circuit.
