Very satisfied
The box was empty at an ambient temperature of 20 degrees on the terrace. After switching on, the display shows an internal temp. Of 19 degrees. Then I set the box to minus 10 degrees, so to the lowest possible temperature. After 27 minutes the display showed 0 degrees in the interior. The control with a thermometer also confirmed this. That was quite fast. After a total of 55 minutes the minus 10 degrees had already been reached and the cooling switched off. I loved it. The thermometer shows a temperature of -9.6 degrees during the test. Approximately every 10 minutes the display jumped from -10 to -9 degrees and the box switched back for about 4 minutes, then turn off at -10 again. Class, which saves a lot of electricity. The next day I set the cool box to a temperature of 5 degrees and re-tested. After about 20 minutes were then reached 5 degrees, the box turns off again. After 26 minutes, the display jumps to 6 degrees, the box turns on and then takes less than 4 minutes to turn off again at 5 degrees. The values will of course change somewhat if the ambient temp. 30 degrees instead of 20, but I can not currently test here in Germany with the sowwetter. I hope this information helps one or the other in consideration to obtain a compressor cool box. This is energy saving.
