New portable electric high-pressure air pump with an integrated rechargeable 12V battery, featuring high performance efficiency and low noise emissions. The dual-cylinder design allows for a very high pressure range, which can be easily set on the pressure gauge. Once the desired pressure is reached, the pump automatically shuts off. The battery level is indicated by an LED. The battery can be charged using the included cigarette lighter adapter or the 230V charger. Direct operation from an external 12V battery (e.g., car or camper) is also possible using the included alligator clips, in case the main battery is depleted. The maximum power consumption is 9A. What makes this pump special is that it combines all connection types: 240V AC/DC household connection, 12V DC cigarette lighter in the car or camper, and battery operation. A single battery charge can inflate up to 3 SUP boards to 20 PSI, after which it needs to be recharged or switched to parallel operation with the 12V DC cigarette lighter. In this case, you can pump and charge the battery simultaneously.
