I got a small about 1.5 cubic foot fridge at a yard sale last summer. Old GE, probably 25 years old, but it’s built like a Sherman tank!
I think it only draws about 100 watts.
I use it for my beer (I brew at home) but if I needed to take some of the stuff out of my main fridge for any reason, heck, it would keep the stuff good and cold!
The good stuff being the beer I presume. Good strategy, though scotch requires no refrigeration. LOL
I home brew also, and need the fridge on ;)
I also have x2 freezers....one to hold meat, and the other to hold all my bee hive frames of honey and beer yeast ;)
If the SHTF, I have ammo, beer, and honey !
