Yes, the perennial question ! There are so may variables that you just can't give a simple answer - it depends on air temperature, extra fridge insulation, is it in the sun, do you put warm food/beer in it etc.

I've stumbled across some well disguised test results for various fridges at 20 degrees and 30 degrees. However the authors realised how rare and valuable actual test results on fridges are, so the info is encoded. But I have cracked the code. (I may be retired, but I have to keep the brain active)

Here are two examples for Waeco model numbers I recognise.

CCF-40
Temp -Run/24hr - % - watts - Amps - amphrs/24hrs - amphrs
20 5.28hrs 22% 45 3.8 19.8 0.8
30 7.68hrs 32% 45 3.8 28.8 1.2

FF-90
Temp -Run/24hr - % - watts - Amps - amphrs/24hrs - amphrs
20 8.4hrs 35% 65 5.4 45.5 1.9
30 10.8hrs 45% 65 5.4 58.5 2.4

Interesting to see that when temperature increases from 20 to 30 degrees that power consumption goes up by an additional 50%.
