I like this! I am thinking of doing it!
My friend had a huge LP tank hooked up to a freezer compressor, worked well until he ran it dry then died, it lasted him a few years but it was damn quiet lol
12 volts?
There are a few 12 volt fridges out there, I could try it out with an old one from the dump. hmm.
That would be sweet if you find a 12V one that performs decently.
how much do those compressors put out?
I currently use one of these and they are great; very powerful and very silent. You need to oil them though, I’d say 8-10 drops every 6 months should do it.
