Description
A jump start machine, also known as a portable jump starter, battery booster, jump starter power pack or booster pack, is a portable device used to start vehicles with weak or discharged batteries without requiring another vehicle.
Modern jump starters use high-capacity lithium batteries capable of delivering a large burst of current to crank petrol and diesel engines. Many models also function as portable power banks, LED emergency lights and USB charging stations, making them ideal for emergencies, roadside assistance and workshop use.
Most portable jump starters are designed for 12V vehicle electrical systems and are suitable for cars, pickups, motorcycles, vans, boats, generators and light commercial vehicles. Higher-capacity models can start petrol engines up to 8.0 litres and diesel engines up to 6.5 litres, depending on the manufacturer.

How a Jump Start Machine Works
A jump starter stores electrical energy in its internal rechargeable battery.
When connected correctly:
- The red clamp connects to the battery positive (+).
- The black clamp connects to the battery negative (-) or a recommended ground point.
- The jump starter delivers a high burst of current to assist the vehicle battery.
- The engine starts.
- The jump starter is disconnected after the engine is running.
The vehicle’s alternator then recharges the vehicle battery during normal driving if the charging system is functioning correctly.
