Ordered for shopping me the box. So I do not always carry along cold packs and bags. I cool the box at home always at 230V before and then put them into the car and hang them up to the electrical system. Unfortunately, the box does not switch off in case of undervoltage, for longer applications I'd buy myself a battery monitor. But for the big shopping it reaches all. The box is cooled to 18 degrees below According umgebeungstemperatur from what I can control and bestätigern. Unfortunately, the 12V connector (45min) after some time very hot and is also difficult in and out in the Bordstekdose but gentle force arrived. The operating noise is tolerable or not audible in our combi in the trunk. The temperature regulation (utility to the?) Only works on 230V not at 12V.Ich never use them, always runs full power. Konstrunktionsbedingt forms after some time condensation water on the ground, but this is normal and not a defect. From me 4 star and Kaufempfelung, there would have been 5 star with battery monitor and better 12V connector.
