I have a 3.9 that I use in this way and it draws about 16 watts (in 95° heat in my garage). I wonder how much of a drain that would be on a battery with an inverter.
For me the big downside is that I don't have a freezer this way. I'm wondering if I can convert a 1 cu ft mini-fridge that I have to be a dedicated freezer, and then rearrange the machinery part of it to fit into an oddly-shaped space.
