12V/110V/Propane Refrigerator

"FWIW the 12V option is almost worthless. It uses about 10 amps, runs continuously and just barely cools. Not surprising as you are using 12V power to heat the refrigerant."

Sorry Dave,

No longer true I am also pleased to be able to confirm, as some others have also mentioned.* When my eutectic system failed, a system which is great until it developes leaks, then very expensive to repair, I kept the well-insulated frig and converted it to 12v only via a Waeco Coldpack conversion set.* It runs on about 1 amp draw, holds her at 4 degrees C no trouble, and with just the addition of an Airbreeze wind turbine to the couple of solar panels I had already added, we can run it 24/7 on the pick with the batts staying essentially fully charged...if there's a wind...minimally discharged and easily brought back up next morning if a still night, with some sun or a bit of travelling & alternator charge.

Here is a similar dsign with specs...

RE: 12V/110V/Propane Refrigerator

Folks wanting to change or test a box for electric use , can use this simple method.

Put a big block of ice in the fridge , close it and next day take out the block and weigh it.

Put it back in and wait a day ., or better 2 days.

Weigh the block of ice.

Under 5lbs per day and electric could be OK , depending on the system.

Over 5 lbs a day , find a better box.

Sears is the place to try this since they sell refrigerators AND scales. I'd suggest running up and down the escalators between departments, though, to get a more accurate measurement of the ice melt. (or grab a bowl from housewares to catch the additional melt!)
