It has helped me make a more informed decision on buying one for myself. Most Thermoelectric coolers are an innovative product on the market because they use science to make your food colder while maximizing efficiency.

The Igloo iceless Thermoelectric Cooler was an enlightening read on these innovative new coolers. The Igloo Iceless Thermoelectric Cooler is a new, energy-efficient cooling technology that allows you to cool your food without electricity. It is a low-cost, all-natural product that can potentially save a lot of money on your electric bill.

Pros And Cons

PROS Of Thermoelectric Coolers

  • Low cost. Thermoelectric coolers are generally less expensive than fridges. They start at $109
  • It is lightweight. These coolers are lightweight and easy to transport.

  • You don’t have to be perfectly level. Thermoelectric coolers work well in an inclined position, unlike many other coolers.
  • It’s easy to use. It’s easy to use. The unit can be run straight from a 12V cigarette lighter or from a powered campsite or home with 240V.
  • Long-life. Thermoelectric coolers are more durable than refrigerators because they don’t have moving parts. They come with a 12-month warranty.

CONS Of Thermoelectric Coolers

They can’t maintain the same cool temperatures that fridges. Thermoelectric coolers are not as efficient as fridges. They cannot reach the same ambient temperatures as fridges, and they can’t freeze items.

Depending on which model, they can cool down to 20°C below the ambient temperature or summer heat up to 60°C above it. A Portable Compressor Driven Fridge Freezer is a better option if you need to set exact internal temperature settings, such as 1degC.

They are heavily dependent on the ambient temperature. They do better in climate-controlled environments, such as air-conditioned vehicles.

Dometic thermoelectric coolers are an exception that can do even better. A thermoelectric cooler may not work in areas where temperatures exceed 30 degrees Celsius. Instead, you can use a portable fridge/freezer.

A drawer fridge can be a great option if you have limited car space. With only 325mm in height, the Evakool 40 Litre Drawer Fridge/Freezer fits perfectly behind the 4WD. You can also use the Drawer unit either as a fridge or as a freezer.

The consistent draw of power. Thermoelectric coolers/warmers cannot cycle, so they should be used while the engine is running. They can draw up to 4 amps continuously and operate on 12 volts. Thermoelectric units can benefit from an optional accessory or in-built low voltage monitor to protect their batteries by cutting off power at low voltage.

You can also choose a small, portable fridge that draws less power and has a smaller design. Bushman Roadie Portable Fridge 15L is a great example. It is a perfect center console fridge, truck fridge, or bench seat refrigerator for back-seat passengers.

What Is The Best Thermoelectric Cooler, And How Do They Work?

Thermoelectric coolers are different kinds of cooler. The electric cooler does not harness the heat potential of ice or ice pack iceless cooler but instead uses the Peltier Effect.

The Peltier Effect causes an internal temperature differential between one area through heat transfer between two separate electrical junctions. An electrical current can be created by applying a voltage to the connected conductors. The current flows through the junctions between the conductors, allowing heat to be transferred from one to the other.

Simply put, the cooler on one side gets warmer and the cooler on the other colder. Your cool items will stay on the cooler side. Some best thermoelectric coolers can heat items while also taking advantage of the hot side.

The unique advantages of an electric cooler over traditional cooling capacity include the lack of chlorofluorocarbons and more precise temperature regulation. They also require less power and can be made in smaller sizes. These coolers are ideal for camping trips and RVs.

It was also invented over 30 years, so you can count on years of experience and testing to bring you THE best when it comes to iceless cooler technology. One user reported using this unit to keep drinks cold and food cold on trips. The user stated that it came as advertised and fit nicely in their sedan, right behind the driver’s seat. Mind you, a thermoelectric cooler can’t keep your food cold when the ambient temperature is above 77 degrees Fahrenheit.

Thermoelectric Cooler Brands

There are many brands involved in thermoelectric coolers, as you might imagine. There are some brands that you may recognize, such as those that make traditional coolers. Others might be new names to you. We’ll be covering the most important brands below.

Thermoelectric Cooler Brands

Koolatron Thermoelectric Coolers

Koolatron is a well-known brand in the electric Igloo iceless cooler market. They do sell some traditional cooler, but their power products are what make them stand out. Many electric coolers are available, from the D25 Soft Bag Cooler and Travel Tote to the more robust and durable Koolatron K85 Krusader. Some wheels are also available in the W65 and W75 Kool Wheeler coolers, wheeled versions of their P65 and P75 series.

They can withstand temperatures up to 40 degrees below the ambient temperature. They can cool down to 20 degrees inside if it’s 60 degrees outside. These units can be turned into heaters by simply flipping the power cord.

You can typically expect temperatures between 135 and 145 degrees Fahrenheit. These products are great for driving. These products do not have a thermostat and can be cooler plugged in and run as soon as you plug them in.

We love the P75 and P20 from them. The P75 is our favorite, as it offers a great compromise between size and performance while still being easy to transport. The asking prices for what you get are reasonable.

Igloo Thermoelectric Coolers

Igloo iceless thermoelectric cooler is a brand most people know. Many people are surprised to learn that Igloo also sells iceless coolers. Although they have gone through many model changes and facelifts over the years, the Power chill 40 and the Breeze 28 are their most popular thermoelectric coolers.

The names of the two models are identical. The Breeze 28 comes with 28 quarts, and the Powerchill 40 has 40 quarts. These sizes are portable and can hold a lot of items.

The Igloo Breeze 28 can drop the internal temperature to 36 degrees, while the Powerchill 40 can go up to 38 degrees. The lids are not heat-resistant, and there is no heating function. However, they are very affordable and reliable despite their small shortcomings. The units can be connected to any 12V outlet or with an adapter for 110V. They can be connected to most power sources in a vehicle or RV.

The PowerShell 40 would be our choice if we had to pick one. This is an excellent purchase because of the increased storage capacity and slight performance boost.

If it’s too heavy, the handle is long enough for two people to hold and lift. The Igloo thermoelectric cooler is small enough to place in between car front seats where you can easily access it while on the road.

Power Source Like most portable coolers, the Igloo iceless cooler is powered by a 12V DC outlet. You can plug the 8-foot power cord into your car’s cigarette lighter or into the DC outlet of a portable generator.

Coleman Thermoelectric Coolers

Coleman is another well-known brand. There are two thermoelectric coolers available from Coleman. Both models are built on the same 40-quart design. For a slight upcharge, the Coleman Powerchill is available in both a cooling and heating version.

The Coleman Powerchill Thermoelectric Cooler can provide a 40-degree drop in temperature. You can also expect a 40-degree increase in internal temperature if the cooler is heated up. This is a remarkable range and one of the highest we’ve seen.

The Coleman Powerchill series’ styling is also very appealing to us. The exterior color and styling of the Coleman Powerchill series are very friendly and will fit in well with any vehicle. It may not be an issue for people who use it as a temporary solution, but it might be for RV owners or those who wish to make it a permanent fixture.

We consider the asking price reasonable and affordable for the ample storage space, excellent operation range, and attractive looks.

This Cooler is Perfect for You If you are looking for an affordable electric cooler large enough for a small family road trip or lunch for 3-4. You want a personal cooler to take on the road for work or long trips. You don’t plan to use the cooler in super-hot climates.

Rockpals Thermoelectric Coolers

Rockpals is one the less-known cooler brands that we have seen. They sell many other products than coolers. They do have one of the best-selling thermoelectric coolers, despite not having much experience. The 30 Quart wheeled cooler is a well-loved item that has been around for a while.

It measures 30 quarts and is portable at the same time. It is also equipped with tires and an extending handle, making it more portable than other electric coolers.

Rockpals claims that temperatures can drop to as low as 45 degrees Fahrenheit for performance. This is an extremely high rating and one of the highest we have seen. You can easily convert your cooler into an internal heater by simply flipping the cord. It has a maximum temperature of 140 degrees Fahrenheit. Although the 12V plug powers it, some conversion kits allow it to be connected to other power sources.

Although the asking prices for this product are slightly higher than those we have reviewed, the superior performance and increased mobility more than justify the extra cost.

Della Thermoelectric Coolers

Della has extensive experience in selling appliances and other home goods. Their 40 Quart 12V Cooler/Warmer is a trendy item in terms of electric coolers.

The cooler offers all the features we love in an electric cooler, including plenty of storage, wheels for added mobility, as well as cooling and heating settings. The cooling and heating elements run at 40 Watts each on the hot and 48 Watts respectively on the beverages cold sides. This combination provides excellent cooling performance, whether you want to keep something warmer or cooler.

We find the most attractive selling point for this product, other than the many features we are looking for, to be the meager price. It is small enough to be among the most affordable electric coolers. There are some quality issues you may encounter, which can be attributed to the low price of this cooler. It is still worth looking at if you have a limited budget.

Wagan Tech Thermoelectric Coolers

Wagan Tech Thermoelectric Coolers

Wagan offers a variety of electric coolers. You can choose from a large 46 quart or a more compact 6 liter Wagan 2260 series. There are many other options, including a 7-liter, 10.5-liter, 14-liter, and 24 liters. These coolers are all targeted at different audiences, but they are still worth noting in this review.

The 46 Quart is the largest size, and thanks to its large dimensions, it’s pretty mobile. From the 226 series to the 6224 series, the smaller cans can hold up to 27 cans. They are perfectly shaped to fit between your car’s seats.

The smaller units performed very well, which surprised us. They can reach temperatures as low as 35°F and as high as 140°F. The ambient temperature will also play a significant role in this range.

Although power output can fluctuate, it is usually between 40 and 55 Watts. This is about average.

We have significant issues with this brand’s quality. Many people have complained about units breaking down prematurely. You may end up having to purchase a new model sooner than you expected, despite the low asking price.

Cooluli Thermoelectric Coolers

Cooluli is a clever brand. We were immediately drawn to it. There are four models available online: The 4 Liter, 10 Liter, and 15 Liter versions, as well as the 26 Liter. These models are all small to medium in size, but they can be used for most purposes.

Cooluli Thermoelectric Coolers’ styling is our favorite feature. They are retro-inspired and stand out from the rest of the competitors. These coolers are one of few that we reviewed that you might enjoy showing off, thanks to their retro look!

These models also have a huge advantage in terms of their ease of use. Many models have digital LED displays that can be switched between hot or cold by pushing a button.

However, the performance isn’t as impressive as other models we have seen. Cooluli claims that temperatures can drop to around 30 degrees. However, the maximum heat can be capped at 120F. It is still possible, but it is not the best.

We would choose the small 10 Liter model if we had to choose one. Its design and ease of use are both a great love.

Black & Decker’s Thermoelectric Coolers

The Black & Decker Thermoelectric cooler was a must-see just because of its name. Black & Decker is a brand that almost everyone has heard of, but very few people know that they also make a thermoelectric cooler!

Despite this, we’re not impressed. The TCs04B can only hold eight cans. The performance is also a bit lacking. The 12-volt power supply doesn’t seem capable of producing the same cooling and heating results as other models. There are also quality issues with the unit being sent out earlier than you might have expected.

Its great mobility and low price are its main selling points. This cooler can be used almost anywhere, and it’s very affordable.

DS18 Thermoelectric Coolers

This brand seems to be new in the thermoelectric cooler market. After extensive testing and research, however, we found that the performance is not there. The same 12V source powers it as we are used to. 26L is the maximum size for this model. This is a large size, but it will make it challenging to keep your items cool or warm. You may also experience quality issues that could cause the product to break shortly after it is purchased.

Energy Efficiency

Since you will be dealing with a cooler that plugs in, energy efficiency should be a priority. A solar-compatible and battery-powered cooler is expensive, but in the long run, it can save you a lot of money.

Thermoelectric Cooling System

This is a thermoelectric cooler. It’s different from a traditional ice cooler or a compressor cooler like your refrigerator. You can read more about how a thermoelectric cooler works in our buying guide. But in a nutshell, the cooler uses a small component called a Peltier thermoelectric plate the size of a matchbox to transfer heat from inside the cooler to the outside.

And while we didn’t experience any durability issues, the cord dangling out the back and overall construction doesn’t give us a lot of confidence that it would last the 10+ years we’d expect from a compressor cooler. However, if a full-on compressor-powered cooler is too much for you, this little thermoelectric box does a pretty great job maintaining the temperature of its contents, cold or hot.

Power draw: Your vehicle’s battery has some reserve capacity, but you don’t want to risk getting stranded by using that all up. Higher power means better cooling power, though available models we looked at only differ by about 20 percent.
