That might actually be really good news. I'm looking at a 12v chest freezer at the moment (on eBay, urgh!) that says it can be used in refrigerator temps as well. If what you say is true, then it might just be the answer I was looking for! I noticed most tubes I saw online were steel coated with copper. They're listed for use as either fridge or freezer tubes, so perhaps the freezer I had before was just terrible quality? It'd be just my luck that the "quality" "Made in Australia" freezer we chose was worse than the "cheap" "Made in China" freezer we're looking at now.
I admit, the 240v chest freezer we converted was around the $600 mark.. the 12v one is around the $900 mark. Ouch hey! It hurt my green heart to throw a shiny scratch-free freezer away last year though, so I don't think I could do it again.
Our family doesn't have any other 12v appliances other than the laptop car charger, mobile phone chargers.. that kind of thing. Thinking of using 12v LED lights.. anything to avoid the cheap inverter and it's losses.
