There are quite a few 12V DC powered refrigerators (less freezers) but most are inexpensive and lacking in quality. Not the Basecamp Fridge/Freezer. The Basecamp runs off both 12V DC and standard AC power sources and can run between 0º-45ºF (refrigerator or freezer). In addition to it's rugged design it can hold a full 63"”quarts of goodness. All of this doesn't come cheap though, yours for about $800 here.
