The handle is collapsible but is comfortable to hold and makes carrying this cooler and heater a breeze. Empty, this compact device weighs only 5 lbs.

To get the perfect of the cooling feature with this portable 18-quart iceless cooler, it is recommended to place pre-cooled items in it and keep it out of the direct sun, as with most other portable coolers.

What you need to know about electric coolers

You may think that an electric portable cooler is a simple device which can serve only a small niche of people and has very few advantages, but you may want to think again. Here is why:

The history of electric coolers

Ever since the first portable cooler was invented by Richard Laramie in 1952, they have been evolving, and today coolers – both iced and iceless are items which nearly any family in the US has.

Today, there are coolers which you can simply plug into your car cigarette lighter plug and which will keep your drinks, snacks or whatever you need cool while you are on the road. The electric coolers can cool your food, drinks, medicaments or other to 40 degrees Fahrenheit lower than the temperature surrounding them.

Now, you can get coolers which can easily be powered by solar energy, so you don’t need to use your car battery or other power sources when camping or traveling.

There are also now smart coolers which can be controlled via smart apps on your phone too.

We have picked the top iceless coolers for you which are in all price ranges, types and sizes.

Benefits of an electric cooler

Have an electric cooler has multiple advantages, even if you think that such a purchase can be a bit too much. Here are some of the benefits of owning an iceless cooler:

  • An electric cooler doesn’t require that you fill it with ice in order to keep your drinks and food cool. This means you don’t need to spend money on ice, and you don’t have to keep stopping at gas stations to buy and add more and more to keep everything cool while you are spending time outdoors. Also, this eliminates the mess of having to drain the melted ice and also have all of your beverages and foodstuffs drenched in water. Last but not least, you can use its entire interior for your drinks and food, instead of wasting half or more of it for ice.
  • With an electric cooler in your vehicle, you will save time and money for having to stop and buy food or eat in a restaurant. Instead, you will have all the food, snacks and beverages you desire while you are traveling, and can eat and drink whenever you decide without even having to pull over.
  • Thermoelectric coolers are more versatile than refrigerators. They are portable, smaller, and compact which makes them suitable for short and long trips. Many of them can be placed as ice chests or upright, so you can easily find space in your vehicle, boat or other for one of them.
  • Many of the coolers can be used for warming food and beverages as well. This is incredibly convenient if you need to keep a meal warm when you are on the road.
  • The thermoelectric principle on which these coolers work is a power-saving, innovative technology. Since there are very few moving parts in these coolers much less power is used for their operation. This means that you won’t drain your car’s battery while you are keeping your beverages or snacks cool.
  • Many of the electric coolers can be used both with 12V DC and with 110V AC power. So, you can use the cooler at home, in your hotel, dorm or office as well.
  • You can use a smaller electric cooler as a nifty lunch box, and keep your lunch warm until it is time to eat by plugging the cooler in your office.

What is a thermoelectric cooler and how does it work?

The thermoelectric cooling technology used for the portable mini-fridges and coolers is based on the so-called Peltier effect. This is the process of the electrical current being applied across an intersection between two different types of metals. This allows for the heat on of the sides of the device to be transferred to the other side. The hot side is attached to a heat sink which keeps the device at ambient temperature and allows the other side to cool down below ambient temperature. This allows for the cooler to cool your beverages and food below ambient temperature, and in some cases, it can take advantage of the hot side and warm your food as well.

The thermoelectric coolers don’t use any harmful substances for cooling, they have more accurate temperature regulation than traditional coolers, and they require less power and are much smaller and lighter than regular refrigerators.

This makes them perfect for camping, RVs, or any kind of trips where there is limited power and not too much space.

Some of the leading thermoelectric cooler brands

There are many companies which are offering electric coolers nowadays, but some of them are more widely recognized. Here are some of the major brands.


Koolatron is one of the most recognizable names in the electric cooler market. It does offer regular coolers, but the powered coolers are what Koolatron is famous for. The company offers a wide assortment of electric coolers, some of the most notable being the two Koolatron coolers in our list – the P-20 18 quart compact and the 29-quart Voyager, as well the following popular coolers (listed from large to small):

Koolatron P65 Kargo 12v Portable Cooler

Koolatron 52-Quart Krusader Cooler (P85)

Koolatron P95 Travel Saver Cooler 45-Quart, Light Grey

Koolatron BC-46SS Kool 48-Quart-Capacity Compact Fridge, Silver

Koolatron P27 Grey Voyager Cooler

Koolatron W65 33-Quart Kargo Wheeler Cooler/Heater, Dark Grey

Koolatron 29 Quart 12V Cooler

Koolatron P9 Traveler III 9.8-Quart Electric Cooler/Warmer, Grey

Koolatron 14-Quart Soft-Sided Electric Travel Cooler, Dark Grey

Koolatron B07 Travel Tote Cooler, Holds Up To 9 Cans, 7L Total Capacity, Cord Storage Compartment

Most of Koolatron’s electric coolers can cool down to 40 degrees Fahrenheit lower than the ambient temperature. These units can turn into warmers with a flip of a switch and can heat your food up to 135-145 degrees Fahrenheit.

As you can see they come in all sizes and shapes, including a small tote cooler and a soft-sided one, so we are pretty sure that there is a Koolatron thermoelectric cooler for just about anyone.

They are all sold at reasonable prices given their high quality and their sturdiness and versatility.


Coleman is another top brand when it comes to coolers. The company offers a wide variety of coolers and only two thermoelectric coolers – both with a capacity of 40 quarts.

We have added the PowerChill to our list of favorites because it can be used both as a heater and a cooler, while as the other electric cooler offered by the company is the Coleman 40 quart version which is a cooler only and comes at a lower price.

The Coleman thermoelectric coolers will drop the internal temperature by 40 degrees, and if you choose the PowerChill it will increase the temperature by 40 degrees when you need to use it for heating. So, overall these thermoelectric coolers have a pretty impressive 80-degree overall temperature range. These coolers look pretty good too, so they are great for both temporary use or as a permanent solution in an RV or boat for example.

The Coleman coolers are also quite reasonably priced too!

Wagan Tech

Wagan offers a wide assortment of coolers ranging from the small personal 6L cooler which we have added to our top best coolers list, and reaching up to 46-quart coolers.

We like the 10.5L personal cooler and heater, also the Wagan 7L cooler and warmer, the 14L version and the mid-sized 24L cooler.

The smaller ones can easily fit on the console between the front seats of your car, and are easy to carry and are actually pretty efficient for cooling, and can cool down 35 degrees, and can heat up to 140 degrees Fahrenheit.

These coolers have a power output of 40-55 watts and are reasonably priced too.


Cooluli offers four different models of electric coolers, the smallest 4L of which we have added to our top list, as well as a 10L option with a capacity for 12 cans and a larger 15L and 26L coolers.

These coolers are all small and medium-sized, but still are sufficient for most people’s needs given the fact that you don’t need to add ice to the cooler to keep the temperatures cool.

They can reach a maximum cold temperature of about 30 degrees below ambient temperature and can be used as warmers with a temperature of up to 120 degrees Fahrenheit.

The good part about the Cooluli electric coolers is their wonderful retro design. Each of these coolers will look great in your office, living room, RV, dorm or anywhere you want.

Features to look for when choosing an electric cooler

You probably feel overwhelmed by the wide choice of electric coolers on the market and are wondering how to make the right choice. Well, here are some of the main features to keep in mind when you are shopping for an iceless cooler.

The storage space you will need

The sizes of these coolers vary from tiny tote boxes up to very large variants. Naturally, they won’t reach the size of traditional refrigerators but they are meant to be portable, so this is perfectly normal.

If you have experience with a traditional ice-based cooler, keep in mind that when you are choosing a thermoelectric one, you will get the full capacity for your beverages and food, rather than having to fill it up with ice first. So, you may want to get a smaller size for your needs than that of your ice chest or another ice cooler.

Access to a power source

Since these devices work only when they are plugged in, you will need to make sure that you will have access to a 12V power outlet for your coolers. Most of them can be plugged into 110V Ac power outlets with the appropriate adapter too.

The cooling temperature you want

Thermoelectric coolers rely on the ambient air around them, unlike traditional refrigerators or ice coolers. So, if you are going to use the electric cooler in extremely hot temperatures of up to and over 100 degrees and your thermoelectric cooler has a minimum cooling range of -40 degrees Fahrenheit, this means that your cooler will only offer a storage temperature of 60 degrees Fahrenheit. So, always consider the climatic conditions before buying a thermoelectric cooler if you don’t want to be disappointed and end up with warm beer and stale food. The same goes for the heating part. If you are going to use the cooler in extremely cold conditions, don’t expect it to be able to warm your meal to a steaming hot temperature.


Do you need a cooler which you can take hiking or trekking with you, or are you looking for a more permanent solution for your RV, dorm or another place? Choose a cooler which will fit the space you have allocated for it, as well as one which you can carry comfortably if you are planning on carrying it around. For a permanent solution, you can opt for the larger capacity coolers which are bulkier and heavier.

Final words

A thermoelectric cooler is a perfect accessory to have if you travel a lot, spend time outdoors or go on road trips. You can use it both in your vehicle and in your home, and it will use very little power.

Thermoelectric coolers are eco-friendly, durable, versatile devices which in some case can be used for cooling and heating, and they are perfect alternatives to traditional ice coolers.

So, hopefully, you have found the best electric cooler for your needs on our list.

We wish you good luck with your purchase and hope that you enjoy the convenience of these incredibly clever devices!
