A complete piece of rubbish that doesn’t cool at all – only if you add frozen water – and after two days’ use it stopped working completely. And I’m not surprised – a product made so sloppily really shouldn’t be allowed on the market at all.
When I buy a fridge, I expect it to cool; the heating function is really useless.

I wouldn’t buy it again.
It’s large and spacious, and it’s easy to pack things away in it
When plugged into a standard socket, it can cool down (we managed to get it down to about 13 degrees) during periods of extreme heat
The cables are in one piece; they’re neatly coiled in the compartments (they have to be put back in there and there isn’t much space), but the 12V cable includes the cigarette lighter plug – it can’t be detached – and there are no USB ports or anything like that.
Since we used it, the car’s ignition hasn’t been working (it may not be directly related, but we don’t know); we’ll see once we’ve had it repaired so that the dashcam works again.
It didn’t cool the car very well; it was warm, or rather, It didn’t keep the cold out very well: (… water had collected inside, so we had to throw away the vegetables and ham.)

At the maximum power setting, the real temperature drop compared to the outside environment is no more than 12 to 13°C (declared up to 20°C), in this mode more noise. When set to lower power it is almost noiseless, but the cooling effect is minimal. When connected to 12V the power control does not work.
Lovely design
Practical internal divider
low cooling power even when set to MAX
higher noise level at maximum power
in car battery connection mode, the power setting is not functional

I have had the product for a very short time, but it works well.
Let's hope it stays that way for many years.

cools well on the highest power, we also used it in the apartment for cooling cheese and drinks. At low power it is almost inaudible, but it doesn't cool down that much. She lasted almost two weeks straight. it's just that the top cover plastics are too soft for them.
cooling well
