Powerful and versatile 3-in-1 jump starter with 1250 A starting current, an integrated compressor and a 12,000 mAh power bank. The BOOST function enables jump starting even when the vehicle battery is completely discharged, while the integrated LED light provides extra illumination when working in the dark.
OSRAM BATTERYjumpstart 1250A is a versatile 3-in-1 jump starter that combines powerful starting assistance, an integrated air compressor and a 12,000 mAh power bank in one compact device. With a maximum starting current of up to 1250 A, it is suitable for 12 V vehicles with petrol engines up to 6.0 litres or diesel engines up to 2.8 litres. The BOOST function also allows starting assistance to be provided to a completely discharged 0 V battery, offering extra security in situations such as winter cold, longer journeys and unexpected roadside emergencies.
The jump leads are equipped with intelligent battery clamps and safety functions that protect against reverse polarity, short circuits and voltage spikes. Clear light and sound indicators help ensure correct and safe operation. The built-in compressor makes it easy to inflate tyres on the road, eliminating the need to carry a separate tyre inflator. According to the manufacturer, the compressor can inflate a tyre from 0 bar to 2.4 bar (35 psi) in approximately 3.5 minutes, making it well suited both for maintaining tyre pressures and for situations where a tyre quickly needs additional air.
BATTERYjumpstart 1250A also works as a power bank for phones and other USB devices, while USB-A and USB-C connections provide versatile charging options on the go. The integrated LED light provides additional illumination for tasks such as working in the engine bay, dealing with a flat tyre or handling other situations in the dark. Thanks to its compact design, integrated accessory storage and included carrying case, the device is easy to keep in the vehicle and ready for use whenever needed. Two-year (24-month) warranty!
