A car jumper, also known as a battery jump starter or portable car battery, is a device used to start a vehicle with a dead battery. It is a portable power source that provides the necessary voltage to start the vehicle’s engine. Car jumpers are typically powered by lead-acid batteries or lithium-ion batteries.
Car jumpers are an important tool for any driver, as they can help to get a vehicle started in the event of a dead battery. They are also relatively inexpensive and easy to use. However, it is important to follow the manufacturer’s instructions carefully when using a car jumper, as incorrect use can damage the vehicle’s electrical system.
