A compressor-driven fridge in an RV is generally powered by
AC/DC power
. This means you can run it off of shore power if your RV is plugged in, or off of your coach batteries if it’s not plugged in.
Is a fridge powered by AC or DC?
There are
DC refrigerators
, for like RVs. (recreational vehicles – campers). Basically they have to turn a compressor and can do so with a DC electric motor and then that just leaves the lighting. However you cannot apply DC to an AC powered refrigerator.
What runs on DC power in RV?
Your
lights, water pump, fans, TV, and radio
run off the DC power system.
Will camper fridge run off battery?
An RV refrigerator will run off of the battery if your fridge model is set up for it or if it uses propane too
. An absorption fridge will run on batteries only for about 3 hours but if using propane too it will last for weeks. A residential RV fridge will last for about 12 hours on batteries.

RV refrigerators can run off of either a 120 volt electrical or an LP gas system
. An RV propane refrigerator makes it possible to keep your food and beverages cold when there are no electrical hook ups available.
Does an RV fridge need power to run on propane?

an RV fridge does not require battery power
, but it does require battery power to open the gas valve and fire the igniter. The front panel LEDs and thermostat are also powered by RV batteries. RV refrigerators commonly use a gas absorption cooling system.
Is an RV furnace AC or DC?
Dan said, RV propane furnaces are
12v powered
, NOT 110v AC powered. They are the biggest battery drain in your RV. It uses 12v power to ignite the propane and to run the fan. All shore power will do is recharge the battery while the furnace is being used.
What is DC on RV fridge?
DC –
Direct Current
in your RV
The DC power stored in your batteries can normally run your house lights, DC outlets, often your hot water heater, your RV heat, and your refrigerator.
How does an AC DC refrigerator work?
An AC-native fridge will have an inverter to convert battery voltage to AC, and
DC fridges will have the equivalent of a DC power brick to convert the AC to DC
. Both styles need a power controller that chooses to run on AC when AC is available.
Can refrigerator run on DC?
Unfortunately,
you can’t plug an AC refrigerator straight into a DC power source
. You need a power inverter between the source and the refrigerator. So the power converts from DC to AC through the inverter, goes into the refrigerator and converts to DC again.
Do appliances run on AC or DC?
Most household appliances and consumer electronics—cellphones, laptops, microwaves, light bulbs, you name it—use
direct current (DC) electricity
. But back when home outlets were first being invented, the decision was made to use alternating current (AC).
What kind of power does a refrigerator use?
Domestic fridge power consumption is typically
between 100 and 250 watts
. Over a full day, a fridge records between 1 to 2 kilowatt-hours (kWh) of total energy usage, or about $150 per year per fridge.
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 long can RV fridge run on propane?
You can run an RV fridge using a 20 lb. propane tank for
280 hours
, or just over 11 days. Tip: Check out our free propane usage calculator in our popular guide How Long Does Propane Last in an RV? to easily calculate the propane usage of all the appliances in your setup.
How much propane does a RV fridge use?
Generally, a 10 to 12 cubic foot RV fridge will burn about
1.5 pounds of propane per day
.
How long will a 20 lb propane tank run a refrigerator?
If you’re using a standard 20-lb propane tank, you can expect it to last around
11 days
(non-stop) before needing to replace or refill it.
Is it better to run RV fridge on propane or electric?
Many agree that
RV refrigerators work better on electricity
, as it keeps the food fresh and cold for a longer period. On the other hand, a gas RV fridge will cool faster and stay colder even in high temperatures.
How do I convert my RV fridge to propane?
Can I run my RV refrigerator on an inverter?
How much electricity does a RV refrigerator use?
The small RV refrigerator ended up using about
5 kWh of power per day
. Our entire battery bank is about 24 kWh. This means that nearly every day about 20% to 25% of all our usable battery power would need to go to powering the refrigerator.
Do camper heaters run on propane?
While your RV’s furnace may utilize electricity to ignite or to control the thermostat,
almost all onboard RV furnaces are primarily run on liquid propane
— which is a pretty efficient fuel source, all things considered.
Do RV furnaces run on propane?
Most RV furnaces run off of propane
. The average RV is manufactured with a propane furnace unless you opt for an alternative, such as a heat pump. Its uncommon but there are a few RV furnaces that have electric heating element options in addition to the propane and can switch between electric and propane heat.
Will camper heat run on battery?
Will a RV furnace run on battery?
Yes, the furnace will run on batteries
. Heat is actually produced from propane, but the blower fan runs on battery. The typical furnace will draw about 8 amps of power.
How does a 12 Volt RV fridge work?
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.
Do they make a 12 volt refrigerator?
Compressor fridges are the most common type of 12 volt refrigerator you’ll see on the road
, and for good reason. These 12 volt fridges are often designed for use in 4×4 vehicles and boats, and they’re built with durability and efficiency in mind – two things you really need in an off-grid adventure vehicle.
