A 12 volt RV refrigerator runs primarily on the 12-volt DC power from your rig’s house batteries (or potentially your car or truck’s starter battery). These refrigerators operate solely on electricity, as opposed to absorption or two-way RV refrigerators that can burn propane to power their cooling system.
How long will a 12 volt battery run a RV refrigerator?
In general, A 12V-50Ah battery can run a 2 cubic feet 12V fridge for 35 to 50 hours before it’s completely depleted. A 10 cubic feet RV refrigerator can run on the same battery for only 10 to 15 hours. However, it’s important to note that: Batteries should not be fully discharged.
How are RV refrigerators powered?

How much propane does a RV fridge use?
RV Propane Refrigerator. The Dometic RV fridge with 8 cubic feet of internal space is rated at 1500 BTUs (British thermal units) per hour. One gallon of propane has 91,502 BTUs. So essentially you could run your fridge for roughly 61 hours off 1 gallon of propane.
What runs on 12 volt in RV?
12v Systems
You can run just about everything else such as a microwave oven, TV, satellite system, computer, lighting and more. The 12v system on an RV is not that complicated but can easily frustrate the best of us.
How much power is needed to run an RV refrigerator?

How many 12 volt batteries does it take to run a refrigerator?
How many batteries are needed to run a 12V fridge/freezer? You can use 1 pc 12V 100Ah AGM battery, or 2 pcs 50Ah batteries to run your 12V fridge for approximately 20-40 hours depending on your fridge’s actual power consumption.
