I bought this for a week camping and it has fulfilled its purpose, the beers are still cold despite 30 ° C during the day (but only 15 ° C over night); During the day we set the full power but nachsüber the Eco mode, this is quiet but the fan is already loud if you set the full power ... Caution: only a 2L or 1.5L bottle can stand! (Spezificher place for it) Also very convenient to keep things cool during a long drive cooling; the cable is long enough to make the box in the trunk (but the 230V cable is in contrast short)
