Has anyone used an inverter to power the outside kitchen mini fridge when not connected to shore power? If so, how did you connect the inverter to battery power. I've watched a few ideas on YouTube but thought I would check here.

I've watched a few ideas on YouTube but thought I would check here. There is no easy way to do this. The biggest issue is the 12volt cables that power the invertor must be heavy gauge wire to handle the current draw. For example: a 360 watt load draws 3 amps at 120 volts, but at 12 volts it draws 30 amps. Watts=Volts multiplied by amps. I don’t know off hand how many watts the outside kitchen mini fridge draws but that should be easy enough to research. I have a 4000watt invertor mounted in my front pass thru storage connected directly to my 3 batteries on the front hitch with heavy duty zero gauge wire. The 120 volt invertor output is then connected to my main breaker box and when turned on will run all 120 volt appliances including the mini fridge. With this setup i didnt need to do anything at the fridge itself. If you only want to install a smaller invertor for the mini fridge only, you will still need to run heavy gauge 12 volt supply wiring from your batteries to it. |

After a very recent 6 hour trip I found that the mini fridge held it's temp pretty good. The contents were well chilled and I added 16 oz jug of solid ice for good measure. Mini fridge temp at start was 34°F and 6 hours later the temp was @ 44°F after three stops were we opened it up to get drinks. The outside temperature that day averaged 75°. So my main concern turned out to be no real concern at all. |
