nameplate requires the device only 7.5 W in 230 V - mode. I received it today and with my calibrated Fluke - remeasured instrument and came to the conclusion that the cooling device will consume more power than stated on the nameplate. If the controller is set to maximum, were to measure 0.39 A, which corresponds to 90.87 W in my current 233 V. If the controller to ECO, were 0.06 A measure, which corresponds to 13.98 W. Mir is a freezer rather that consumes more power than indicated because power consumption and performance and thus faster cooling and perhaps cooling at very high ambient temperatures in a car used in a standing position. More power consumption = more power = good. Thus, assessment is positive. In idle mode 27 ° C were measured inside after 3 hours 5 ° C, without contact with calibrated Fluke thermometer at ambient temperature. The air or the warm side of the Peltier elements were readings by 32 ° C, I bought the device to replace an older, about 5-year-old, about the same sized Mobicool device that has given up the ghost at 230V operation by clearly audible hissing noise (the typical noise of dying equipment). I think that due to construction and electrical measurements, the new device will be better than my old one. TIP: I take the device with even the hotel room and the operating noise of my old machine was really disturbing. The controllability allows a nearly silent operation. But please: always check the internal temperature by refrigerator thermometer! What we have from an almost silent operation when everything is hot then. By controllability you can adjust the temperature inside the content. Conclusion: device consumes more power than stated on the nameplate, but should thus also do more. Despite not correct nameplate no devaluation, because overall very good styling, especially enough space for the cable. Cover easy to remove.
