1 complaint: If the charge pump consumes, it takes 30h to load it. When his boat but want to pump up every day (eg on holiday) you will not make it to load completely (the day has, after all, grad mal 24)
2. The pump has not managed to inflate the boat. It takes quite a long first (with the lifting pump I was faster finished) and is quite noisy. Then I'm assuming that the pump can not muster enough pressure because from nem certain degree of filling just walked no more air into it and the boat was far from filled correctly.
It has also quickly heard the sound of the pump, that the power does not last long.
So unsuitable for inflatable boats.
Smaller items I have not tested, so it can be that it served its purpose there.
I have in any case sent back
