Planning your next great adventure? While you’re probably into exploring the outdoors along with your RV, or maybe you’re someone that likes to live off-grid, you still don’t want to sacrifice some of your creature comforts by any means.
Perhaps the last time had you realize that your cooler was not any good at storing your food for more than a day, leaving them less than frozen, with all the ice melted. Worse, they don’t seem edible anymore as a result.
You need a reliable portable storage freezer and cooler to keep your meats and dairy fresh while camped out in the middle of nowhere.
And besides, your family of 6 could definitely use homestyle cooked meals, which will not be possible if you don’t have decent cold storage to begin with.
But first, you have to learn about portable refrigerators, yes, they do exist, and they are very useful. To be exact, a 12-volt compression refrigerator is worth considering. Coolers remain an option and work just fine. However, it really depends on your specific needs, plus how much you’re willing to spend.
Once you get used to having cold drinks in your camper, you’ll realize that they are RV accessories must-haves.
I have categorized the choices into three, namely: top overall portable refrigerator (Dometic CFX), top dual zone refrigerator (Dometic CFX dual zone), and top cooler (Dometic Tropicool). You’ll be assured that anyone’s needs will correspond to at least one of these categories.
You might wonder why I have chosen products from a single brand. Again, this article is not a paid endorsement by Dometic. If you are an RV owner, you must have items bearing this ubiquitous brand name. Dometic is an industry leader in the US when it comes to innovative RV appliances. Their range of products does not only include refrigerators and freezers, but also air conditioners, heat pumps, toilets, awnings, etc.
Dometic 12 volt refs have many features that set them apart from other brands. The portable freezer from their CFX line is perhaps the best I’ve seen. How many others can boast of a temperature of -8 degrees Fahrenheit in a compact size that can be powered by 12 volts? There are portable freezers that can only go as low as zero degree temperature. And that’s just miles apart when it comes down to comparison.
You may think an eight-degree difference is not much of a big deal. After all, at zero degrees, it’s enough to keep your chicken and other meats frozen. Well, I have two words for you: ice cream! It’s a delight to know you can bring frozen treats on your trip, which can be as good as being bought from the store. Aside from ice cream, you can also bring ice to cool your drinks anytime you want.
Portable RV Refrigerator and Freezer in one
Then there’s the dual zone type of 12-volt portable refrigerators. Dometic CFX-95DZW is the real deal. It has both a ref compartment and a separate freezer area. You can set either compartment as both a fridge or a freezer with its adjustable temperature control.
There’s also a smaller yet efficient version with Dometic CFX-65DZ, among other brands. What happens is, the cold air emanating from the freezer section provides the chill for the ref portion. Given this design, the ref temperature is limited but should be enough for food items that need only light refrigeration.
And if you want a simpler option, but durable nonetheless, Dometic’s coolers will provide you just that. Interestingly, they are quite unique because they don’t act as a cooler alone. They can also serve as a food warmer of sorts that can provide heat up to 149 degrees Fahrenheit. You can’t find this feature in other portable coolers. Dometic units have 7 different settings, boosting its versatile function.
Given the variety of intelligent cooling units Dometic offers, many RV enthusiasts including me, favor them over brands such as ARB and Whynter. These 2 other companies sell 12 volt RV refrigerators as well. In my opinion, however, they don’t hold a candle to Dometic’s superb quality and innovation, not to mention the price. Yes, these brands are even more expensive, yet their cooling capacity is inferior compared to Dometic’s. It can’t be helped to extol Dometic portable refs and freezers any RV fanatic will surely love to have.
Top pick for Portable RV 12-volt Refrigerator and Freezer
RV Compressor-type true portable refrigerators vs thermoelectric coolers
Let’s take a look at refrigeration that comes in a convenient portable size, but is also powerful enough to get the job done. A 12-volt fridge that uses a compressor can be quite expensive, but in hindsight is still cheaper compared to any of your primary kitchen appliances.
After all, if you want a device that will work as if you brought your own home refrigerator with you, then getting one is worth your money. And what’s truly amazing is it runs on very low power at 12 volts.
Such type of refrigeration can be operated using your RV’s starter battery or through solar panels. You can also stick the plug of some models into the cigarette lighter receptacle to power it on. These portable refrigerators can also withstand the rough travel ahead without breaking or stalling.
Thermoelectric coolers, on the other hand, have a compressor-less design. It has an upper hand when it comes to the price; it is more affordable than a true portable refrigerator.
However, it can only maintain a certain temperature that’s dependent on the outer climate.
If you have an RV refrigerator, a freezer even, and it can keep your dairy cold at about 40 degrees Fahrenheit, then it is a compressor-type, and electrically assisted. While it is certainly not cheap, it will make your life on the road a lot more comfortable.
After a long trip, you sure don’t want to find spoiled food, which you’ve meticulously stored because you thought a thermoelectric cooler will cut it.
Why compressor-type portable refrigerators are the best option
- Offers true cooling properties that will help preserve food items for a long time
- The compact size will not take up so much space yet offers you home ref-like refrigeration
- Has adjustable precise temperature controls which thermoelectric coolers like the Dometic Tropicool do not have

More info about portable 12V refrigerators
To enable you to bring more food and to keep them fresh like it came out from your home ref, buying a real portable fridge makes a lot of sense. Their source of power will make quite a big difference in terms of how cold your interior temperature will be, which most meat and dairy require to preserve their quality and nutrients.
Portable refs could be compressor-type, absorption, and thermoelectric. When you know each one’s takeaways and tradeoffs, you will be better equipped to decide which type of portable fridge is most effective for your needs.
Portable Refrigerators (compressor type)
- Efficient by using low battery power
- Temperature can be set precisely
- Can chill to lower temps, regardless of ambient temperature
- Operates effectively on uneven terrain
- Can serve either as a fridge or a freezer
- Most preferred than absorption type and thermoelectric refs
Among the three types of portable refs, the compression ref is the only unit you can consider that will offer real cooling. They function like your big home fridge with its compressor technology, only it is smaller, and operates on 12 volts. Its ability to adjust the temperature accurately, ranging from 0 degrees Fahrenheit to 50 degrees Fahrenheit, allows you to set it according to the contents you intend to cool.
If you have the dual zone type of portable fridge, you have two partitions. One is for the freeze function, and the other to provide just the right amount of refrigeration so that your food doesn’t spoil fast.
The temperature of the interior typically remains unaffected by the exterior climate. So whenever you adjust the temperature using the digital controls, you will get a precise cold output. However, an extremely high temperature outside may still impact the coldness of your interior despite the adjustable settings.
Compressor type portable refs use DC power, which you can harness using your vehicle’s battery. With its battery efficiency, you can be assured that it consumes very low power. You have to remember though that during hot summer months, your ref will be forced to keep the interior temp cold by working up your battery. As such, you will consume more battery when it’s always used in warmer climates.
Nonetheless, compression refs usually use lower than 1 amp per hour, proving its energy efficiency. As you may experience with your very own home ref, the compressor unit is not always powered on and instead, runs in cycles to maintain its required interior temperature.
Most, if not all cooling devices, have a built-in sensor that will trigger once the desired temperature is reached. This way you don’t use your battery power wastefully. Should you intend to use your portable ref more often, you must think of getting another battery to power it up so you don’t end up draining your car’s battery in the process.
Continuous operation regardless of inclined position
You know that a normal house ref that uses a compressor should have a leveled position. The portable 12V ref is special in such a way that even if your RV roughs it up on an incline or drive steadily on the road, it will function without a hitch. This is something an absorption cooler cannot do because it has to be placed on a flat surface.
The best type of portable RV refrigerator
It is for the above-mentioned reasons and more, why the compressor type 12V portable ref is the best there is, with its high-quality cooling being its primary asset. This kind of refrigeration is necessary, especially if you are looking at storing your meats and other food items for more than 24 hours.
Disadvantages of Portable Refrigerators (compressor type)
Compression Refrigerators are expensive
When you go to warmer climates for your trips frequently, you will utilize more amps per hour to keep the cold inside. In this regard, it will be best for you to purchase a separate battery so that you don’t drain your vehicle’s own. You should only consider this if you almost always have to use it during months of extremely high temperatures.
If you actually decide to buy a dedicated battery, you will need a source that will enable it to be recharged. You have two options then, you can harness solar power to recharge your battery, or, you can do so with the help of a portable generator. Both options are costly and unfortunately, there’s no other way around it.
Compression Refrigerators emit a slight noise
This is not really much of a disadvantage. After all, you must already be familiar with the compressor noise of your household fridge when it runs to maintain the cold temp inside. You know this is normal and unavoidable, in fact, it’s not as noisy compared to a regular ref. And besides, they only emit noise during the first few minutes of operation, and will usually subside thereafter.
Portable Refrigerators (absorption type)
- Flexibility in terms of power sources
- Highly efficient if gas is utilized
- Will only operate on leveled ground
- Static temperature
- Lowest temperature possible is 30 degrees Fahrenheit
- High electric consumption at ten times more than its portable counterparts
Also known as a 3-way ref, an absorption type portable ref utilizes heat energy to provide cooling. The “3-way” label refers to power sources such as LPG, 12 volts DC power from either battery, or solar energy, and 240 volts AC power output.
It consumes a lot of electrical power equivalent to ten times more than a 12-volt compressor type portable ref. As such, hooking it up with your vehicle’s battery is not a viable option because it will most likely drain it in no time.
If you plan to get this type of portable ref, it’s almost imperative to get a separate battery that’s catered solely to your unit. Or, if it’s also possible for you to have a means of recharging the battery, otherwise, you have to pick out another power source for your portable device. And for this reason, you might as well turn to use an LPG.
Absorption type portable refs use gas in the most efficient manner. Users, however, should keep it in a place with good ventilation and open space. When traveling on the road, you should bring enough gas supply, or remember to refill it at any gas station.
Portable coolers (thermoelectric)
- Offers a cheaper alternative for once in a while usage
- Capacity to chill and warm food items
- Will offer no cooling when the ambient temperature is more than 77 degrees Fahrenheit
- Emits a distracting noise
- Consumes more battery power unlike a portable compressor type ref
More reasons why someone who is always on the road will need a 12V portable fridge
Let’s get one thing straight, a portable 12V ref is not only highly recommended for RV and motorhomes. Anybody who is often on the road and relies on his vehicle, whether it’s a hatchback or a pickup truck as his home away from home, should consider getting this type of cooling device. And even for someone who wants to have it in his home, may it be in a small room, or an individual who rents a cozy apartment with limited space can always count on a portable fridge to deliver. In other words, its multi-purpose functionality is undeniable.
Here are some of its popular uses:
Have one handy during camping trips
You could be a solo adventurer or be part of a wolf pack with your family and friends; you can definitely use a portable ref to feed you or your entire group during breaks from your outdoor exploration. A 12-volt mini fridge can stay in your vehicle or nearby while camped out in the wilderness.
Sustain your nutrition while on the road
You’re visiting from one state to another, embarking on a long road trip to visit relatives you haven’t seen for the longest time. You decide to bring them food as your potluck for your homecoming of sorts. Thanks to your portable ref, you can preserve the integrity and quality of your food despite the long travel.
Beat the trucker blues
A trucker’s life can be lonely and difficult at the same time. You can pull off an all-nighter if you at least manage to feed yourself with healthy food items, which can only be preserved when you store it in a compact ref that fits in your vehicle. Plus, a cold drink or soda would be nice to have in between hours of driving.
Use for cold storage in a log cabin
And because you only stay in your rustic cabin every other weekend, it’s not too practical to place a regular ref inside it. Instead, you can bring with you your 12-volt mini ref and take it inside. This way, you can cook meals from your stored raw ingredients without much hassle and maintenance.
If there’s one thing that separates 12-volt portable refrigerators from coolers, that is the price. A thermoelectric cooler typically ranges from 100 to 300 dollars. On the other hand, portable refs with compressor technology will set you back at least 500 dollars, which can run up to a thousand bucks depending on the brand. It’s really important to determine your usage to get the most out of our cooling unit.
