Best Thermoelectric Cooler

Thermoelectric coolers are a great option for off-grid living or even for tiny abodes. They do not utilize the function of ice packs to keep your food at optimal temperatures. Thermoelectric coolers are also simply known as powered coolers, or electric coolers. The name gives away just how they keep your food cool. They need to be plugged into a power source to operate, which means you need to be sure that wherever you’re headed, there is a plug somewhere for your trusty thermoelectric cooler.

An awesome benefit of a thermoelectric cooler is there is no end in sight to how long your food will stay fresh in this cold storage space. Their cooling benefits are far more extensive than the regular ice pack cooler and some come with nifty extra features too! Let’s take a look at the best electric coolers offered on the market today.

Best Thermoelectric Cooler Buying Guide

As you have seen, there are plenty of models to choose from, and knowing exactly where to begin. However, we have a detailed guide below on what to look for when choosing the best thermoelectric cooler. We will say, that you shouldn’t expect your electric coolers to function as well as a mini-fridge would – but close. Follow our features to look for when buying your next best thermoelectric ice box to find the best option for you.


How much stuff do you expect your thermoelectric coolers to carry? Do you frequently go on big family trips or host barbecues or tailgate parties? If so, then you would need one that is 48 quarts and above. For those who like quaint family outings or just parties with a few close friends in attendance, then one of 30 quarts or smaller will do.

Also, consider the type of food or drinks that you tend to bring. If you often need 2L bottles of soda, then definitely look for one that can accommodate the bottles with space to spare. One thing thermoelectric coolers offer that is a significant advantage over regular coolers is the iceless operation. This means you do not need to account for extra space for ice packs.


Electric coolers are electric (duh!), so you need to be close to a power source for them to work. However, we know a few types above that can keep the contents cold for up to a day without power – pretty impressive! Most of these thermoelectric coolers are design to work with a standard 12V power source, and most plugs in North America operate on the same voltage. Therefore, looking for the best thermoelectric coolers would mean one that has a 12V power adapter and other methods of connection if necessary.

Also, even for a small electric tool, powered coolers can use a fair amount of power. Look for ones with low power consumption and maybe even eco-friendly engineering to save a few bucks.

Temperature Requirements

For this section, one would need to consider the climate they live in and the temperature they need their coolers to perform at. The standard is 40 below 0 Fahrenheit, which means take whatever temperature the outside is and minus 40. In some climates, the ambient temperature could be much higher than others and 40 below just won’t do the trick for storing snacks and drinks such as ice cream and cold beer.

If keeping the temperature in the ice box 40 below isn’t enough, then we suggest going for thermoelectric coolers that can maintain temperatures at 40, or whatever temperature you need regardless of the outside environment.


How easy is it to tote the electric coolers around with you? Coolers are like mini-fridges but are easier to transport and lighter in weight. The reason why someone would purchase electric coolers over a mini-fridge is to take them with you, so the next most important thing to look out for is coolers with handles or wheels. We will admit that if you aren’t planning to setup camp anywhere for an extended period of time, then iceless coolers aren’t the best choice.

This is because they need to be near a power source to work. If you are spending your days hiking around, you can’t have a cooler that relies on a stable and stationary power source. But if you are just planning to get from your car to the site, then make sure your thermoelectric coolers have handles at least so you can lug it around. If it features wheels then that model will definitely earn bonus points.


As you have noticed, some of the best electric coolers have warming abilities as well. This will give users the option of keeping contents cold or warm. This means that you can take whatever food you want with you and some options even have dividers to separate cold and hot contents.

The Lid

The design of the cooler lid will impact your accessibility of the contents For example, one with a secure latch may offer a tighter fit, but getting to your snacks can take longer than one with a magnetic closure. We mostly see coolers with a lid that opens from the top, but there are certain designs that also offer side openings as well.

The next consideration is to think of how many lids do you want? There are powered coolers that offer two lids that won’t require you to expose the entire opening just to access one thing. The more you open the lid, the more the outside air will creep in and alter the interior temperature. Too much opening of the lids will cause the food to not stay fresh for as long as it could.


Some fridges offer separators or dividers to designate different compartments for the snacks. If at any time you need to separate the contents for different levels of coldness or otherwise, a split compartment is just what you need. These types of coolers also give coolers with warming capabilities an added advantage.


Does the brand matter? In many cases, consumers tend to gravitate towards well-known brands. But with famous brands come hefty price tags. Is it a necessity to go with established brands? It does have its benefits but we wouldn’t say it is always the better choice. Consider the reviews, as they are from real consumers that give you their two cents about the operation of the product.

While there is bound to be negative reviews here and there, you have less to worry about if the majority are positive. Who knows, you mind find a gem of a thermo-cooler that is exceptional in its capabilities and comes at an affordable price!


Lastly, the price is also of significant consideration. It is the lowest on our buyer’s guide because we feel that the other factors and your needs will outweigh the price. That’s not to say that you should go out and buy the most expensive premium choice out there, but it is worth it to note that the price doesn’t necessarily indicate quality.

As mentioned, if you go for a well-known brand, there is a very high chance that you are paying a few more of your hard-earned dollars for the reputation of the company and not the product itself. You are mostly looking at a price range of 1-300 for a decent, yet affordable cooler. Anything above that would be premium options with features that not a lot of us need for everyday trips.

You can find a wide range of products on our list, from one with the best value for your money to an affordable option too. Before you settle on a price, don’t let yourself pass up a good choice just because it exceeds your budget. For something that you rely on to keep edibles fresh, we would definitely not suggest compromising the quality for the price.

Benefits of a Thermoelectric Cooler

Thermoelectric coolers are quite affordable and do not require ice refills and ice packs that will cost you extra money. You know that they will always provide the best cooling services if they’re near a plug. One other benefit of not having ice packs or other refrigerants is the risk of leakage. Once your ice starts to melt, not only will the food potentially spoil, but the cleanup can be a headache as well. They are as well built as any cooler or fridge and offers the value of a regular fridge without the bulky body and high price tag.

These coolers give you the ability to set the temperature and keep it there stably. Depending on what you bring with you, this could be a very important feature to keep things fresh and yummy. They are also smaller and less cumbersome than mini-fridges while offering more versatility than regular coolers with their warming techniques as well. You won’t find that in a mini-fridge we’ll tell you that right now.

Expert Tip

One drawback of thermoelectric coolers is their inability to handle poor weather conditions. They cannot get wet as regular coolers can, so if you plan on using it outdoors, definitely place a tarp over it or keep it in a shaded area. When finished, store it somewhere indoors and do not leave it outside.

Did You Know?

Thermoelectric coolers can still keep your food cold without electricity if the interior is already chilled. They are designed to withstand power outages and can keep your food cold for hours. Also, reducing the frequency of opening the lid will prolong this period.
