vilioli4 months ago000Hello, do you have to remove the batteries to charge them or are they charged automatically when connected to the mains?Show in original language (German)Anonymous4 months ago000No, the batteries are only for "emergencies", e.g. if you have no mains connection. They are also not supplied. I would always recommend pumping with a cable and mains connection, as the pump requires a lot of energy.Show in original language (German)Comment
