The pump has a eigebauten battery. When connected to the vehicle power 12V can the pump use the same battery and load. At 230V only invite. On the valve adapter you can plug other adapters, for example, which for "French" valves with bayonet closure. Thus, super flexible handle. Negatives: The pressure is not so high that you can inflate a larger boat (300-400 kg payload) so taut. But I must say that you have halfway inflated with the pump in about 5 minutes and then the boat can make in about 5 minutes by hand the rest. Only by hand took you about 40 minutes and was really competitive sports. Therefore, I still highly recommend the pump. PS: misused it can also be readily used for lighting in charcoal after the boat tour ;-)
