The motorhome must be connected to mains electricity before the 220V sockets in the motorhome can be used. If that is the case, please check the charging station; on older campsites it can sometimes happen that it does not work optimally anymore. You will soon notice this when you hook up your mobile phone charger to the station. Are you 100% sure that you are properly connected to electricity, and does it still not work? Then please contact our experts.
