The Gyspack Heritage combines a 6 V and a 12 V jump-start function in one device. This booster is capable of starting both seasonal vehicles with 6 V batteries and modern vehicles with 12 V batteries. Additionally, it powers electrical devices with 12 V direct current thanks to the two integrated 20 Ah batteries. The Gyspack Heritage allows for an immediate start of seasonal vehicles due to the two 6 V batteries. The parallel use of two 20 Ah batteries gives the Heritage an energy reserve of 40 Ah. With the two integrated 20 Ah batteries, electrical devices such as TVs, lamps, laptops, and coolers can be powered from the 12 V energy source. The Heritage features a built-in lamp equipped with 7 powerful LEDs, making it very suitable for emergencies in darkness or when lighting is insufficient.
