General Discussion / Re: Alternative Fridge?
« Last post by Joseph on September 25, 2025, 11:08:11 am »I’ve installed the 12 volt conversion. Took all of 3 1/2 hours. 100 degree day the fridge cooled down to 10 degrees in freezer and 40 in fridge in a bit over 3 hours. It’ll need to run a bit longer to get the fridge colder. I’m still figuring out the settings to dial it all in.
They had told me I may need to run a 10 gauge wire if the wiring wasn’t heavy enough. I didn’t want to get stuck with having to figure it out after the install so I did that first to be sure I could. That took an additional hour but wasn’t that difficult and in the end wasn’t needed. I left it in place even though it’s not hooked up.
On our last trip prior to the conversion my batteries failed and the only option was a couple 12 volt marine maintenance free batteries from Walmart. They are supposedly 100 amp hour , so 200 all in. On a 100 degree day I get roughly 18 hours of my fridge before 50%. I think it’ll go longer after due to the fridge requires more power in the beginning to bring it down to temp. Once it reaches the desired temp it runs roughly 65% of the time, or so they say.
