Battery-free jump starter with capacitor technology. The Voltcraft quick start system boasts unbeatable advantages: it does not need to be charged beforehand and is ready for use even at extreme temperatures ranging from -40 °C to 65 °C. The residual current from the discharged car battery is converted into energy by the capacitor in no time, allowing the Voltcraft quick start system to start the engine. The LC display provides information on the relevant data regarding the starting process. Maintenance-free, reverse polarity and short-circuit protected, compact, and mounted in an ultra-safe design with full protection, this device offers the most user-friendly and safest way to jump-start a vehicle. The lifespan is also impressive: up to 10,000 uses are expected.
