Bought for a field trip. There was an important criterion that it could cool down to minus (it cools down to -18 in fact, it froze a 1.5 liter bottle of water in 4 hours). And that would eat not much electricity. In eco mode consumes 3.2 amp. H. in normal mode 3.7. If you set 5 degrees, then empty, up to this temperature, working on battery power in eco mode from +23, it cooled down in 40 minutes. Empty from +5 after turning off the compressor raised the temperature to +7 in 12-15 minutes, after which the compressor turned on again for 10-15 minutes. And someone else wrote in the comments that the type does not work through the application, but everything works fine for me. In the application, it is even more convenient to watch and set everything up than manually on the refrigerator itself. And of course we'll see how long it lasts.
Adding some photos was a no-brainer to better illustrate my experience.
