1. Best Pick- Engel AC/DC Portable Fridge/Freezer
Our best pick was a close contest, but this 40-quart mobile fridge/freezer from Engel came out ahead of the pack. Its combination of durability, size, user-friendliness, and performance makes it an excellent option for any traveling family.
This compact, high quality model has a top-opening lid and a narrow profile so it’s easy to fit in your vehicle. The exterior case is made from shock-resistant ABS plastic and is perfect for off-roading or marine adventures. It has reinforced corners and integrated handles for easy portability.
The Engel can function as a refrigerator or can be set to freeze or maintain frozen products. The temperature display control dial is located right on the side by the handle and can be quickly adjusted.
The swinging lid can be set to open from the right or the left side. This is a tough refrigerator/freezer and can maintain operations when tilted up to 30°.
The exterior of the Engel measures 25 x 15.5 x 18.5 inches and the interior cooling chamber is 14.5 x 10.5 x 14.4 inches. It weighs 48 pounds empty. The capacity is rated at 40 quarts or about 37.9 liters.
Where this refrigerator/freezer really earns its top status is with the design of its compressor. This fridge/freezer has fewer moving parts and is more energy-efficient than other refrigerator/freezers.
The “swing” compressor means that the Engel doesn’t require extra power to initiate the cooling cycle. It also means that the compressors in an Engel last longer and require fewer repairs over the course of their lifespan.
It operates on AC 110/220V or on a DC 12/24V battery. The fridge/freezer can be wired into both AC and DC power at the same time. It will automatically switch to AC power when available.
Despite its overall high-quality, the Engel does have a couple of disadvantages. While the case and compressor are sturdy and long-lasting, the latches for the lid are notably fragile.
In addition, the latches are not covered under the warranty. The fridge/freezer still works well even when the latches are broken though. However, a product at this price point should not have this problem.
Also, the control dial can be a bit tricky to set because the dial is not marked. You have to look closely to be sure you have selected the correct setting. A simple white mark on the dial would solve this problem.
Overall, the Engel is considered an excellent unit for keeping food products cold and for safely storing temperature-sensitive medications like insulin. It is a rugged fridge/freezer with a wide range of features that can handle bumps in the road and is resistant to corrosion. With a 3-year warranty, your investment is well-protected.
- Exterior is made from shock and corrosion-resistant ABS.
- Swing compressor is energy-efficient and durable.
- Switches automatically to AC power when available.
- 3-year limited warranty.
- Lid latches are not covered under warranty.
- Dial is missing a visible marker.
- Pricier than other models with a similar capacity.
2. COSTWAY Portable Refrigerator/Freezer
Costway’s dual-chambered portable refrigerator and freezer is best for a family who wants a large-capacity fridge/freezer with great features at a budget price. Designed for durability, this model is compact for the capacity and has a drop-in shelf to keep your food products organized.
Like the Engel, the Costway has a narrow profile and fits easily into a car, truck or RV. The top-swinging lid allows you access to the interior while the digital LCD panel is located right on the handle. The exterior is sturdy and helps cushion the components during transport.
It can be set to refrigerate or freeze items with its powerful compressor. In addition, it has two interior compartments and comes with a drop-in shelf for the bigger one.
This refrigerator/freezer can be operated in several different modes and includes fast-cooling and energy-efficient settings. The Costway also has a range of three battery-projection settings to prevent it from draining your battery.
This model measures 27 x 13.5 x 21 inches and weighs 36 pounds when empty. The smaller section measures 6.25 x 10 x 10.5 inches and the larger interior space is 12.5 x 10 x 17.5. It has a 52 liter capacity or about 54.9 quarts between the two sections.
It can operate on a DC 12/24V battery. Otherwise, you can use the included adapter to hook it directly into your AC power outlet. It is not designed to be hooked into both AC and DC power simultaneously.
The Costway is a budget refrigerator/freezer unit with solid features. While the exterior case is sturdy, the handles and lid-latch are rather fragile.
The LCD control panel also seems to be less-reliable and subject to errors. You may need to periodically unplug this fridge/freezer and allow it to reset. The Costway is not designed to be used indefinitely like a home or mini-fridge/freezer.
Overall, the Costway is considered one of the best units for a family that needs the capacity and prefers a budget option. The dual-partitions make it easy to organize your food, drinks and medications if you’re going on a trip and the drop-in shelf is a handy bonus.
The manufacturer’s limited warranty is only good for 1 year. You should consider adding an extended warranty to best protect your investment.
- Dual-compartment design makes organizing the contents a breeze.
- Multiple settings include fast-cooling and energy-efficient modes.
- Offers 3 levels of battery protection.
- Handles and latches are fragile.

3. Alpicool C9 Portable Mini Freezer
It may not appear as fancy as some other brands but the EdgeStar is a very reliable 43 quart refrigerator/ freezer with good features. It has an insulated steel gray exterior with riveted handles and a metal draw-latch to lock it closed. The generous interior space is organized by two drop-in wire baskets so you can always find your food products in a hurry.
The metal exterior offers you more insulation-power than other materials. It has a compressor based cooling method that freezes more quickly than its Thermoelectric counterparts.
It can keep your food cool for hours even without power. This model has a digital control panel and is very simple to adjust. The handles fold down when not in use to make it easy to fit into your vehicle.
The EdgeStar can operate while you drive as long as it is supported by straps or a bungee cord. Its top-swinging lid is well-insulated and the hinges and latch are sturdy and unlikely to corrode.
Additionally, it can be set to refrigerate or freeze. It also has a fast-freeze mode to rapidly cool it down.
The EdgeStar exterior dimensions are 20.8 x 24.7 x 17.7 inches while the inner chamber interior space is 14.96 x 11.42 x 18.50 inches. It weighs 48.5 pounds when empty.
Additionally, this refrigerator/freezer features a large and a small drop-in basket to organize your food and drinks. It has a capacity of 43 quarts or about 40 liters. It can hold approximately 60 cans of soda.
The EdgeStar can operate on AC 110/220V power or a DC 12/24V battery. It is not designed to be hooked into both power sources simultaneously though.
This fridge/freezer is best used in a truck or RV for a trip but is not as durable as those made from ABS or other plastics. The metal exterior makes it less-optimal for marine applications as the casing may eventually corrode.
The metal exterior is insulating but can also be dented and scratched easily. Luckily, a few dents won’t affect the function of the fridge/freezer.
The clean digital display panel is based on the lower corner near the power supply socket. Therefore, it can be tricky to access depending on how you have your freezer positioned.
Where the EdgeStar falls short is with its warranty. While it is advertised as a 1-year limited warranty, the fine print makes it clear that the warranty is 90-days for labor and 1-year for the parts. It would be best to protect your freezer with an extended warranty.
Still, it is a good option for less-active pursuits like setting up a base-camp or transporting groceries. It may not be best for boating or off-roading though. However, it can stand up to outdoor use and would be a solid choice for an RV if you like to road or day trip.
- Metal exterior provides superior insulation even without power.
- Large and small drop-in baskets make organizing easy.
- Simple to understand and operate.
- Fridge/Freezer is less durable than other brands and not ideal for off-roading.
- Location of the display panel is potentially inconvenient.

The exterior of this highly efficient mini fridge/freezer measures 22.4 x 12.6 x 12.6 inches and the inner interior chamber space is 13.5 x 9.5 x 7.5 inches. There is an extra 2.5 inches of height provided by the lid. So items under 9.5 inches tall should easily fit inside. It weighs 27.78 pounds when empty.
This fridge/freezer is as tough as they come and can operate even while at a 45° angle. It can be set to refrigerate or freeze and has an energy efficiency-mode. It also comes with 3 battery-protecting settings so you won’t accidentally drain your car battery.
Additionally, it can run off a DC 12/24V battery. Otherwise, you can use the AC adapter to plug it into a conventional 110/240V outlet. It isn’t able to be wired into both AC and DC systems at the same time. Its either AC or DC. It has a capacity of 21 quarts or about 19.8 ltrs.
This model is an excellent portable fridge/freezer but it does have some limitations. While it is compact and about the size of a standard cooler, the insulation and compressor make it heavy. You might need two people to safely move it when it is full.
There is no latch on the lid either, although the gasket seems to do a good job of keeping the lid closed. The handles are well designed for durability but their position could make it a little awkward if two people are moving it.

There are some drawbacks to the Dometic and the primary ones are the size and weight. Its small capacity makes it less useful for multi-day trips or camping. When filled, it will likely be heavier than a similar-sized cooler.
The Dometic has an automatic sensor to prevent your battery from dying but these settings are not adjustable. You don’t have the option to turn them off if you don’t want to use them. This shouldn’t be a problem while your vehicle is running but could be annoying if you are using the freezer overnight.
Aside from these minor issues, the Dometic is considered a great choice for the right family. It is best for day-trips and keeping your drinks and snacks cold.

Even with two people to support it, this fridge/freezer makes for an awkward load. If you are moving camp frequently this might not be ideal.

Portable Freezer Buying Guide
If you are looking to purchase the best portable fridge freezer for camping, road trips or other outdoor adventures then you are in good company. As more families hit the road on extended adventures, the demand for better food-storage space has grown. With a portable refrigerator and freezer you can easily bring perishable items and medications along on your road trips.
What is a Portable Freezer?
While commonly referred to as portable freezers, they can actually function as both a refrigerator and freezer. Just like the full-sized versions in your home, a true portable freezer works via a vapor-compression refrigeration system (VCRS).
There are four parts to a VCRS and they are: a compressor, a condenser, a thermal expansion or throttle valve and an evaporator.
Without boring you with too much technical information, a VCRS works like this:
- Vaporized refrigerant is moved through the compressor where the pressure is increased.
- The compressed refrigerant flows through the condenser, where it is turned from a gas into a liquid. Heat is released during this process which makes the condenser hot to the touch.
- The liquid refrigerant then moves through the throttle valve and into the evaporator. The refrigerant removes the heat from the evaporator which in turn removes it from the area to be cooled (the inside of your portable freezer).
- The vaporized refrigerant is cycled back to the compressor to restart the cooling process.
To see this process in action, it’s best to check out this animated video. It demonstrates how a VCRS works to remove heat from the inside of your refrigerator.
A portable freezer/refrigerator has a thermostat that can be set to maintain a particular temperature. The compressor will automatically kick on when the temperature inside rises above the one set on the thermostat.
As you can see, a portable refrigerator/freezer is an intricate, highly efficient device. This is why they are more expensive than electric coolers.
In addition to the VCRS, a portable refrigerator/freezer will have an exhaust system and vents to expel heat from the condenser. The display panel allows you to adjust the settings on your freezer and to control the thermostat. A portable refrigerator and freezer is more complicated to operate than your average home refrigerator and should be closely monitored while in use.
Portable Freezer vs. Cooler
A cooler with ice packs may work for short excursions like a short day trip but they can’t keep food fresh for more than a few hours. These coolers can’t maintain frozen foods. If you want to store your food and medications at a safe temperature on longer trips, you’ll need a portable freezer/refrigerator.
These refrigerator/freezers are versatile, high quality, efficient devices but they are not for everyone. While a portable refrigerator/ freezer can be an asset for any family, they are also more expensive than an electric or ice-packed cooler.
So how do you know if a portable one is best for your family? Continuing reading to find out.
A portable mini freezer is a refrigerator/freezer best designed for travel. They are compact versions of your home device that can run off the battery in your car, RV or boat.
These refrigerator/freezers give you peace of mind knowing that your food is safely stored no matter how far you go.
Unlike a cooler, you won’t need to bring along an ice pack or buy bags of ice. They can operate off a variety of power sources (see Power Source below for more information) so they’re are highly efficient.
The main advantages of using a portable freezer over a cooler are:
- Stores food and medications at precise temperatures indefinitely.
- Capable of refrigerating and/or freezing foods.
- Eliminates the need for ice packs or bulk-ice for cooling.
- Able to maintain controlled temperatures even when it is hot outside.
- Can be modified to run off of almost any electrical power source.
How “Portable” is a Portable Freezer?
A small portable freezer can be maneuvered by one person. Some even come with a carrying-strap to make it easier. A portable model is compact but heavier than a similar-sized cooler.When filled with food, however, the more sizeable portable refrigerator/freezers will require at least two people to safely move.
The design of a portable refrigerator/freezer creates a few limitations to their use. The two biggest things that can diminish the performance of your portable fridge/freezer are hot temperatures and dust.
To keep them portable, they are not heavily insulated like their in-home cousins. Your portable refrigerator/ freezer will heat up faster when it is hot outside and will have to work harder to maintain your set temperature.
To avoid straining the compressor, it’s best not to operate your portable refrigerator/freezer in the direct sunlight. Instead, you should place it in a shady and protected spot to keep it cool.
The exhaust system creates an additional limitation. A portable refrigerator/ freezer will need to have space around it while it is on for the air to circulate. Otherwise, it could overheat and potentially cause a fire.
If you are using one in your vehicle you will need to be sure it has enough clearance. You can’t pack things too tightly around a portable freezer while it is in operation. You should never run a portable refrigerator/ freezer in a hot, enclosed location such as the trunk of a car.
Dust is an ever-present challenge. It comes in an endless supply in the great outdoors. Dust can accumulate on your refrigerator/freezer’s components and can reduce its ability to function.
It can be challenging to prevent when you are using the freezer outdoors each day. So it’s best to always wipe down and clean the freezer well before and after use.
Make sure the coils and power supply are kept dust-free and clean. You may want to invest in a cover for your fridge/freezer if you frequently use it outside for camping or other activities.
How To Choose a Portable Freezer
Once you have decided to take the plunge and buy a portable refrigerator/freezer, you still have a few things to consider when looking at the different models before you make a final decision. These fridge/freezers are available with a wide range of features. They can vary in price from around $200 for an average budget refrigerator/freezer to over $1000 for a large premium one.
The best things to consider are the capacity and the power supply when reviewing our list of portable freezers.
The capacity and design of a portable refrigerator/freezer will determine how much food it can hold. Portable refrigerator/freezers get more expensive as the capacity increases. So you want to choose one that’s the best size for your family.
Capacity can be reported in several ways. This can be very confusing since different companies use different measurements. Most commonly, the capacity of a freezer is measured in quarts or liters. A small portable refrigerator/freezer may have the capacity of 16 quarts (or 15 ltrs.), for instance.
Some companies also rate the capacity based on how many cans of soda the unit will hold. So a 16-quart refrigerator/freezer can hold about 20 cans of soda.
A larger size portable refrigerator/freezer with a capacity of 65 quarts can hold over 100 cans of soda. When comparing fridge/freezers, it’s a good idea to translate all the capacities into quarts to make the side-by-side view a bit easier.
Larger, heavy duty freezers on our list often have two inner chambers. This allows you to set one section for refrigeration and the other for freezing.
These freezers can organize your food on pull-out or drop-in shelves. On the other hand, smaller, average size models will have a single chamber that can either refrigerate or freeze foods.
The one thing that portable refrigerator/freezers have in common is that they all require electrical power to operate. You want to be sure that the one you choose on our list will work with the power sources you have available.
Most portable freezers come with power cords to run off your home electricity. The AC (alternating current) power cord can be plugged into any common electrical outlet.
Many also come with a DC (direct current) adapter, and this is where things can get interesting. Using a DC adapter allows you to run your portable refrigerator/freezer using a 12 or 24-volt vehicle battery. You can often plug it directly into the adapter in your car.
If you are using your refrigerator/freezer in an RV, you can hook the DC adapter into that battery system for power. Many portable freezers can be modified to run off of a propane-powered electrical system as well. However, you may need to purchase additional equipment to make it work.
Portable freezers are also a really good option for operating off a solar-powered battery. If your RV has a solar panel system already set-up, then this might be the best option. Alternatively, there are small portable solar panel kits on the market that are suitable for running a portable model.
You might also consider using a gas-powered generator or a portable power station to run your portable refrigerator/freezer at a base camp. Then you can keep your food fresh even while you’re camping or living off-the-grid.
Tips For Using a Portable Freezer
To get the most out of your portable freezer, follow and review these best practice below:
- Always store your freezer in the upright position and keep it protected from excessive heat and moisture.
- Keep the coils and power supply free from dust and debris. Follow the maintenance schedule listed in your instruction manual.
- For the best freezer performance, pre-cool your freezer for 30-60 minutes before adding your food to it. If you can, refrigerate and/or freeze food in your home fridge and then transfer the cool or frozen items to your freezer for transport.
- Periodically use an external thermometer to measure the internal temperature of your freezer. Compare it to the one set on your thermostat. You may need to adjust your settings to achieve the desired temperature when it is hot outside.
- When using your freezer outdoors, place it in a shady location that is sheltered from the dust/wind. It’s best to avoid placing it in damp locations, close to a road or where it could be rained on.
- When using your freezer in a vehicle, be sure it is strapped down so that it won’t shift around while you are driving. Check that your freezer has the necessary clearance and that the exhaust system is free from obstructions.
- Never use a portable freezer in an excessively hot environment or without adequate circulation.
- Use a backup battery, generator or power bank to charge your freezer overnight to prevent it from draining your car battery.
Frequently Asked Questions
Q: What is the difference between a portable freezer and an electric cooler?
A: The difference between a portable freezer and an electric cooler is that a true portable freezer uses a vapor-compression refrigeration system (VCRS) to remove heat from the fridge/freezer compartment. These freezers are basically miniature versions of your home refrigerator. They can be set to maintain a specific temperature.
The thermostat will turn on the compressor when the temperature rises above that setting. When operated under ideal conditions, a portable freezer can refrigerate and/or freeze perishables and drinks.
Unlike a VCRS-based appliance, a thermoelectric cooler has no moving parts. Instead, an electrical current is run through metal plates inside the cooler.
This causes one plate to get warmer while the other gets cooler. This process is known as the thermoelectric or Peltier effect. The interior of your cooler drops in temperature as the heat is transferred from the cool plate to the warm one.
A cooler is able to maintain an environment that is about 20°F cooler than the surrounding air temperature. These coolers are not able to hold the interior to a specific temperature and they can’t freeze or maintain frozen items.
Q: How does a portable freezer get power while traveling or while camping?
A: It depends on your freezer. If your portable refrigerator/freezer comes with a DC power cable then it should be able to run off of a 12 or 24-volt battery while your traveling or camping. These batteries are commonly found in cars, RVs and boats. Other DC-power options include: gas generators, power banks and using a solar panel system.
Some portable refrigerators/freezers also come with an AC power cord. Therefore, you can run it off your home’s electricity. If your freezer is a DC only appliance, you can get a DC-to-AC adapter that will allow you to use a conventional outlet.
Q: Does a portable freezer work when it is hot outside?
A: Yes, a portable freezer will work when it’s hot outside. But depending on the conditions it might not work as well. It’s best to check the specifications. Many portable refrigerators/freezers are reliable up to around 90-100°F.
When the outside temperature goes above that, the thermostat may not be able to maintain the set temperature. From a practical standpoint, when it gets hot outside you might not be able to freeze something new. However, your refrigerator/freezer should still be able to keep the previously-frozen items frozen.
Q: Could you drain your car battery by using it to power my portable freezer?
A: Yes, you could drain your car battery by using it to run your portable refrigerator/freezer. This can happen if you use your car battery to power your freezer while the car is not running.
There really isn’t any risk of draining the battery while the car is moving, however. Some refrigerators/freezers have a battery-protection system that will shut the compressor down if it is in danger of draining the battery too much.
In that case, you could potentially lose some of your perishable items. If you plan to use your refrigerator/freezer at a campsite, it’s best to have another system available to charge it overnight.
Q: How quickly does a portable freezer cool down once it is plugged in?
A: It depends. Most portable refrigerators/freezers can reach refrigeration temperatures (32-40°F) in about a half an hour. It may take longer for it to reach freezing. However, most will be able to maintain frozen items after 30-60 minutes of pre-cooling.
If you spend your leisure time on the road or frequently go on extended adventures like camping trips then you need a portable refrigerator/freezer.
