The RV refrigerator is always a hot topic (a hot topic about cooling, that is!). There are different types of RV fridges, but in this post, we’re looking specifically at the 12V RV refrigerator.
How is a 12V RV fridge different from a traditional RV fridge, and what are the pros and cons of having one?
We’ll look at all the details, and we’ll show you some of the best options available for those of you who are considering a 12V refrigerator for your RV.

What Is a 12V RV Refrigerator?
In our post about the RV refrigerator in general, we discussed the various types of RV fridges and how they work.
We noted that an RV fridge can work on 120V AC supplied by shore power (such as that provided at a campground’s power pedestal), by LP (liquid propane) gas, or by 12V power supplied by a battery bank that can be charged by an engine’s alternator or by a solar system.
Some RV fridges have the ability to work in two or even all three modes.
Traditionally, in fact, RVs were supplied with fridges that could cool in 120V AC power mode when plugged into shore power, OR in LP (gas) mode when boondocking (not connected to any other power source), OR in 12V DC mode when the engine’s alternator is running.
How Does a 12V RV Refrigerator Work?
A 12V fridge exclusively runs on 12V DC power at all times. Power consumption varies based on the quality of the compressor used by the fridge’s manufacturer.
While 2-way (or 3-way) fridges are absorption refrigerators, a 12V fridge uses a compressor that operates exclusively on 12V DC power, eliminating the need for both LP (liquid propane) gas and 120V AC.
In the RV environment, a 12V fridge is most often powered by the rig’s house battery bank (often charged by solar panels), though it can also be powered by the alternator of a vehicle or motorhome while the engine is running.
So what’s the difference? In a nutshell, an absorption fridge uses heat to trigger a chemical process that creates cold in the fridge & freezer compartments, but a 12V-only fridge uses only electricity to run a compressor to create a cold environment. (This has its advantages and its drawbacks as we’ll see momentarily.)
Many van and car campers use small and/or portable 12V compressor fridges, but for the purpose of today’s topic, we’re referring to the larger version such as this 10 cu ft residential-style Dometic fridge.
A 12V RV refrigerator is similar to an RV residential refrigerator that always runs on 120V AC power (like the one we have), however, there are a couple of significant differences.
The most significant difference is that you need an inverter to run a residential fridge in an RV. An inverter is necessary to convert 12V DC power into the 120V AC power that a residential fridge uses.
With a 12V RV fridge, there’s no need for an inverter because there’s no need for that conversion. The fridge runs directly on the 12V DC power supplied by the rig’s battery bank.
This is a benefit of a 12V fridge over a residential fridge because an inverter isn’t 100% efficient, so power is lost in the conversion. That extra power draw is eliminated with a 12V fridge.
But the other difference is size. Residential refrigerators come in a much wider range of sizes, including much larger than is available in a 12V RV fridge model. For example, the 12V fridge shown above is a 10 cu ft unit while our residential RV fridge offers 18 cu ft of space… and you could even get a 21 or 24 cu. ft residential refrigerator (if you had the room AND it could fit through your RV’s door, window, or windshield!).
Most RVs still come from the manufacturer with absorption fridges, so for the purposes of this post we want to compare the 12V RV fridge with the more common absorption RV fridge powered by gas and electricity.
What Are the Advantages of a 12V RV Fridge?
A fully 12V RV refrigerator has several advantages over an absorption fridge. (And like anything else, there are a few drawbacks as well.)
Let’s take a look at the benefits of having a 12V RV fridge.
Strong, Consistent Cooling
12V RV refrigerators cool very well… and do it very consistently (like their 120V residential counterparts). This is one of the main advantages of a 12V fridge, in fact.
Absorption fridges have a longer, slower cycle of cooling. This can lead to greater variation in temperature within the fridge and freezer compartments, leading to a greater likelihood that food will spoil. On the other hand, a 12V compressor RV refrigerator will keep the contents of your fridge cool consistently at the temperature at which you set your fridge, extending the life of the food inside.
More importantly, perhaps, an absorption fridge can typically only cool to about 40° below ambient temperature. So, if it’s 90 degrees ambient temp during a summer camping trip, your RV’s absorption fridge is likely to cool only to 50°F at best. Not great for keeping your food from spoiling.
No Ventilation Required
The 12V compressor fridge is strictly electric, so it doesn’t require ventilation. Absorption refrigerators need a path for the heated air to flow up and out the top, which is why they have extra venting.
Less Fire Hazard
A 12V RV compressor fridge doesn’t have the same potential to create a fire hazard that an absorption refrigerator does (due to its use of propane gas to create heat in order to cool the unit). With a 12V fridge there’s no propane and no flame. This all but removes the risk of fire.
This is no small consideration in light of the fact that propane-fueled refrigerators are among the top causes of RV fires.
And thanks to the lack of propane involvement, there’s no debate about driving down the road with your propane tank on. There are also no tunnel delays or re-routing, etc.
More Interior Space
Because the compressor-based cooling unit is smaller than an absorption-style system, 12V compressor refrigerators offer more interior space in the same footprint. This is great if you plan on replacing your existing absorption fridge… without having to increase the size of the opening, you can get a unit with more capacity inside!
No Need to Defrost!
Due to the active cooling process found in most 12V RV fridges (and in 120V residential fridges), an automatic defrost system is possible in 12V fridges and freezers. Absorption-style fridges don’t have that option, so they’re prone to frosting up.
A built-in defrost system is a big deal to use full-timers who have neither the interest nor the time to defrost the fridge and freezer every month or two.
What Are the Disadvantages of a 12V RV Refrigerator?
As we acknowledged earlier, there are a few disadvantages to having a 12V RV refrigerator.
One of the drawbacks of a 12V fully-electric compressor fridge is that they’re quite expensive. With that said, though, the truth is that all decent RV refrigerators are expensive.
Require Extensive Power Off-Grid
If you enjoy boondocking as much as we do, you’ll need a fairly substantial battery/solar setup to run a 12V RV fridge off-grid for long periods (or a good onboard or portable generator to keep your 12V batteries charged up).
Although the 12V RV fridges (non-portable) that we’re covering today are fairly sizable, they won’t work for everyone.
If you’re RVing with a large family or if, like us, you’re living in your RV full time and you plan to boondock in faraway places for extended periods of time, 10 cubic feet won’t be enough space. (This is why we moved to a residential refrigerator, in fact.) Residential, 120V AC refrigerators still come in larger sizes than the largest available 12V compressor refrigerators… so if size is important, you may need to look elsewhere.
What Type of RV Refrigerator Is Best?
This is one of those questions that can only be answered based on your personal traveling situation and your camping style.
If you have access to an adequate power source (like a decent-sized solar system) or if you’re literally always plugged into shore power, then a 12V RV fridge might be the best RV refrigerator upgrade for you.
If, however, you’re an avid boondocker who camps only in moderate ambient temps and you don’t have a large solar system & battery bank, you may love having a propane-fueled fridge to keep your food and beverages cool WITHOUT having to worry about keeping your batteries topped up.
If you’re living in your rig full time and/or you’re traveling with a large family, you may want to opt for a residential refrigerator, especially if you tend to always camp at RV parks and campgrounds that offer shore power (or you have a very substantial solar system & battery bank).
See, it’s really all about your particular needs and how you camp.
12V Compressor Residential-Style Refrigerators for RVs
You’ve read this far, so obviously you’re still interested. So let’s check out five popular choices for 12V RV refrigerators. Again, in this post we’re looking at residential-style 12V compressor fridges and not chest-style portable compressor fridges or portable freezers.
Note that most of these 12V refrigerator manufacturers make multiple sizes of 12V residential-style fridges. For the purposes of this post, we’ll highlight a similar-sized fridge from each manufacturer.
Dometic is a well-known brand with an excellent reputation in the RV industry. The Dometic DMC4101 is a 10 cu. ft. 12V fridge with sleek residential styling and easy-to-use digital controls.
