Have the device only on loan from my colleagues, for a 2-week holiday to seventh (three children). We have had the device used with 220V power supply and were completely satisfied with the cooling capacity, despite the children often had what done and out. After the initial purchase, and even a whole holiday with gas utilization came and it really is again a difference in performance to remember. Are rather sad not earlier rising to the cooling possibility to, instead always the air-cooled units with appropriate cooling and sound solution. TOP for each camper and also holidaymakers who has enough space in the vehicle for it. Footprint is of course not to forget.
