hy, sorry can't measure it as I don't have such an appliance. I have compared this fridge with many before I bought it they all had the same consumption value E or F on the scale🥴 with the small ones there doesn't seem to be an "efficient" one.

I was wondering the same thing. I've now got myself an electricity meter (Voltcraft SEM6000 CH.). According to this, the fridge consumes around 23-25 watts every hour when it is running at full power and is practically full, i.e. +- 0.6 kwh per day. That would be approx. 220 kwh per year. Still clearly too much for such a small fridge, especially as it only cools to around 9.5 degrees at this maximum level according to the external temperature meter.

The specified 450 kw are incorrectly entered by the manufacturer (!!!). The refrigerator actually needs around 52 watts under full load (when it is cooling). For some reason, the manufacturer has simply extrapolated this to a year (0.051 kw per hour = 1.23 kw per day = 450 kw per year), although the refrigerator does not cool continuously.

Hello "Anonymous" I have a MyStrom adapter hanging on the back. However, I have the larger one (115L).
In my conservatory at an outside temperature of ~Ø28°C, it consumes around 80W during cooling, and 2.1W during the holding time.

+1 to the question. Other fridges consume about 80 kWh. Is this one just have very bad insulation? Maybe because of a glass door?.. Or is the description wrong and in reality it consumes less?

Sorry, 2000kWh is my personal goal. Of course, it has nothing to do with the 2000Watt society.
