I am on my second 12 volt chest freezer/Fridge. the first one lasted about 16 years then failed (Compressor cycled on/off/on/off/on/off almost as fast as I type and I type fast. So I got a replacement.. (Liked the original better but the 2nd one is good) It's kind of a spare/backup/ transport unit only a couple cubic feet. Right now it's got Perogries. Turkery Burgers.. 6 pounds of IQF Blueberries (it froze them the think is set to -4° F) And a bunch of "Ice blocks" I toss in my thermal bag before I go shopping for cold food. Works great.
I still like the other one better (All freezer) no "Refrigerator" compartment)
Oh both of 'em could be adjusted to "Refrigerator only" if needed.
The moral of this post: Like most everything made by man.. Failures happen.
