If you’re looking for an electric cooler for car trips like vacations and camping, you can choose between a thermoelectric cooler or a compressor-based true refrigerator. Comparably speaking true refrigerators are much more expensive and heavier than thermoelectric models. You probably want an electric cooler for car adventures that is compact and lightweight.
Whether you choose a real refrigerator or a thermoelectric car fridge, both are iceless. That means that you don’t have to buy ice to cool them down, you don’t have to continually replace the ice as the existing ice melts, and you don’t have to deal with the cold water that results from the ice melting.
Ice can also make a mess of your food and beverage containers if they aren’t designed to soak in water. You don’t have to worry about that with an electric cooler.
Ice takes up room in a cooler, so if you buy a specific size ice cooler, you can count on having to use a good deal of space in the cooler with ice at the expense of food and beverages.
You’re obviously looking for an electric cooler that will keep food and beverages cold, but many thermoelectric coolers have the ability to warm as well. You can’t do both at the same time, but you can choose to use your cooler as a food warmer to keep food and beverages warm on the way to camping, a picnic, or other outdoor adventure.
In this article, we are focused on the cooling capability of these thermoelectric coolers.
There are some important differences between real refrigerators and thermoelectric coolers that you should consider when choosing an electric cooler for car trips.
A true, compressor-based refrigerator works like your refrigerator at home and can be set to very cold refrigerator temperatures. If you want your food and beverages to be cold instead of just cool, then the true refrigerator is a better choice.

The number one complaint of customers related to thermoelectric coolers is that they don’t get cold enough. That’s not necessarily the fault of the coolers which do not have a compressor and are dependent on ambient temperature to determine how cold they can get. Most have the capability to reduce the temperature of the cooler up to 40 degrees below the ambient temperature.
Ambient temperature means the temperature of the air in the immediate surroundings of the cooler and can be dramatically different from the outside air temperature. For instance, the outside air temperature could be 70 degrees F while inside a hot parked car where the plug in cooler is could be over 100 degrees F. On the other hand, if the vehicle is running and the air conditioner is running, the ambient temperature might be significantly lower than the outside air temperature.
If it’s hot in your car the car refrigerator is not going to get very cold possibly struggling to get to 45 or 50 degrees F. This may be cool enough for some food and beverages, but if you’re looking for ice cold beer, it’s not going to cut it. Many manufacturers even recommend that you pre-chill food, beverages, and the portable refrigerator prior to using it.
Size and Weight
Larger coolers take up space and will displace other items you may want to carry on a trip. If you are taking a big crew, you may have to get a larger cooler to meet their food and beverage needs. Otherwise, you may be able to get away with a smaller model.
Keep in mind also that larger coolers take longer to get cool and need to run longer to maintain a cool interior. If you’re not going to fill the cooler, it will not cool as fast and will not maintain your food at cold temperatures as easily.
Vibration and Orientation
The thermoelectric module is actually a small solid state heat pump that is not affected by tilting, jarring, or vibration. This may not be the case with some compressor-based models which may need to be kept in a specific orientation and which may not be designed to withstand the vibration and jarring of car travel.
A compressor-based refrigerator uses more power than a portable electric cooler that uses thermoelectric technology. In some ways, that makes a thermoelectric cooler a better traveler in the car than a compressor-based refrigerator. If you need to leave it on while the engine is off, the thermoelectric cooler will not drain the battery as fast as the real refrigerator.
Both types plug into an available 12-volt vehicle power port or if you buy an optional 120-volt adapter can be powered from household current.
Be careful when using 12-volt power ports like your vehicle’s cigarette lighter. Some power ports stay on when you turn off the vehicle and others shut down. If you need the cooler to stay on when you leave the vehicle, be sure and choose a port that stays on.
On the other hand, if you’re not expecting the cooler to stay on and you plug it into an always-on power port, you could run down your battery quickly without realizing it
If you want your food and beverages to be cold no matter what the ambient temperature is, you need a compressor-based real refrigerator. You will pay a premium for the additional capability as portable refrigerators can cost three or more times as much as some of the best and largest thermoelectric coolers.
If you carry medicine with you that needs to stay cold, you may need to choose a real fridge model just to guarantee that your medicine stays cool.
Here are some desirable features you will want to look for in any cooler you choose.
A thermoelectric cooler can run down your battery in as little as just a couple of hours. To prevent this, some models come with a low-voltage cutoff that will turn the cooler off automatically when it senses low voltage conditions.
When loaded, coolers are heavy and if you keep it in your vehicle while traveling could cause a lot of damage and serious injury if not properly secured. The best way to secure any cooler is with a seatbelt if possible, but in any case make sure it’s secured while traveling.
Look for handles and/or wheels on the cooler that make it easier to transport. Filled with food and drinks, coolers can be very heavy and having built-in handles, a swing-up handle, or wheels can make the difference when you’re trying to load it into the car, taking it to the campsite, or carrying it into the hotel room.
Unlike ice coolers, thermoelectric coolers have motors and fans. They make noise and depending on where you place the cooler in your vehicle, it might be annoying or distracting. If you have passengers who have to sit next to it on the back seat, the cooler may create a noisy, uncomfortable environment.
They pretty much all claim to be quiet during operation, but you really need to check reviews to find out how annoying each really is.
We also looked at several coolers that are designed specifically for use inside a vehicle complete with cup holders, but only one from Black & Decker got high enough ratings to be added to our list. Part of the problem is their size which is smaller than any of the other units in our list and also because they are designed specifically for vehicle use and don’t have as many features that would make them a good choice away from the vehicle.
We searched forums, consumer sites, customer review sites, retail sites, and manufacturer sites for the best rated thermoelectric coolers for cars and we think we found ten that you should consider.
Take a look at our list and see if one of these thermoelectric coolers is the best cooler for your travel and vacation adventures!
