Battery capacity: 1.8Ah (20Wh). Battery types: 12V - (wet, gel, AGM, Start&Stop). Charging current: 500A jump starter and power bank with lithium battery (LiPo technology = lithium polymer battery). Quick start for motorbikes, cars and vans with 12V battery. SMART BOOSTER CABLEit protects against reverse polarity and short circuit and it prevents jump start operation when the FAST battery is discharged (voltage below 11V). DISPLAY LCD: The bright display shows the charge status of the internal batteries and the inputs/outputs. High J-BME3s: The energy supplied by the jump starter within three seconds of cranking to keep the engine running. Reduced weight and size, the lithium battery stores four times the energy of a lead-acid battery of the same weight. Fast charging.
