How to Choose the Best Thermoelectric Coolers?

Thermoelectric coolers are more powerful in terms of performance, so selecting the right cooler requires careful consideration, as not all models are created equal. To benefit from the model adapted to your needs, it is necessary to take into account these features:

The sound level

The sound level emitted by the operation of an electric cooler is defined by the refrigeration technology with which it is equipped. At this level, the thermoelectric cooler is the least silent. Indeed, this slight disadvantage is mainly caused by the operation of the compressor of the device. The sound level of a thermoelectric cooler can be between 40 and 46 decibels or even a little more. Even if this cooler is not very discreet, it is appreciated for its great capacity to freeze or cool food and drinks.

Storage capacity

The storage capacity of a thermoelectric cooler should be chosen according to the number of people it needs to accommodate. If a capacity of approximately 8 L is sufficient for the needs of one person, for the needs of a family of approximately 4 members, the ideal is to choose a model of at least 30 L.

The capacity of a thermoelectric cooler varies between 10 to 100 L, or even more for certain models. For large families, it is easy to find a large-capacity thermoelectric cooler on the market. In addition, to easily store cold drinks and other food, there are compression coolers equipped with several compartments. A cooler with a larger storage capacity may have a compartment for cans and bottles, and another for food such as fruits and vegetables.


It is essential to check the sturdiness of the thermoelectric cooler before buying it. During its use friction and shocks with other objects cannot be avoided. Some rubbing can therefore leave scratches on the surface of the cooler. A low-quality exterior coating will not withstand various frictions and shocks for long. These types of coatings are present on entry-level coolers. We advise you to avoid these coolers and opt for sheet steel or very solid plastic coating. These coatings guarantee the robustness of a cooler.

The practical side

The practicality of a thermoelectric cooler influences its ease of use. Indeed, this type of cooler is often heavy. To make it easier to carry and move, we recommend the presence of wheels for large coolers. You can also choose a shoulder strap for small coolers.

Removable and retractable carrying handles are also necessary to be able to store the cooler easily. It should be noted that some handles also allow you to lock the lid of the cooler. Finally, the presence of interior lighting is a criterion to be taken into consideration. This element makes it easier to see what the thermoelectric cooler contains in complete darkness.


Another very important criterion is the size of your cooler. A cooler with a good capacity but a little too bulky could be a problem for you. This is the case if you want to use the cooler on a fixed point, or if you want to transport it regularly. These are the largest compression, absorption, or hybrid coolers.


This criterion will be decisive, especially if you want to move your cooler regularly. Mine stays in the trunk of my car most of the time so I almost prefer it to be a little heavier (so it doesn’t move around in the trunk). Now if you are looking for a very mobile thermoelectric cooler to move regularly, make sure it is not too heavy (less than 20 kg). Also make sure that the device has handles, handles, see wheels to transport it more easily.

The price

There are all price levels for thermoelectric coolers: from around 30 dollars to more than $500 for the most advanced models. Here too everything will depend on your use. If it’s only to be used once or twice a year, there’s no need to go for a model that costs more than $100.

On the other hand, if you plan to use it more regularly, do not hesitate to go for a medium or even high-end model. In any case, we advise you not to go on a low-end device, even for occasional use. You will quickly be disappointed by this kind of cooler.


Are thermoelectric coolers suitable for long-term cooling or only short-term use?

Thermoelectric coolers are best suited for short to medium-term cooling needs, such as day trips, weekend getaways, and camping adventures. While they can maintain a cool temperature for an extended period, they can’t reach the same low temperatures as compressor-based refrigerators for long-term storage of perishable items.

Can thermoelectric coolers be used to keep items warm as well?

Yes, many thermoelectric coolers come with a reverse function that allows them to switch from cooling mode to heating mode. This feature makes them versatile for both cooling beverages and keeping food warm during cold weather.

Do thermoelectric coolers require any maintenance?

Thermoelectric coolers are low-maintenance devices. Since they don’t use refrigerants or have moving parts, there is no need for regular maintenance. However, it’s essential to keep the cooling surfaces clean and free from debris to ensure optimal performance.

What are the limitations of thermoelectric coolers?

Thermoelectric coolers may have limitations in achieving extremely low temperatures compared to compressor-based systems. They are also dependent on ambient temperature, making them less suitable for extremely hot environments. Their cooling efficiency can also be affected by the size of the cooler and the insulation quality.

Are there any safety precautions to consider when using a thermoelectric cooler?

To ensure safe and efficient use of thermoelectric coolers, avoid blocking the vents or airflow around the unit. It’s also essential to adhere to the manufacturer’s guidelines regarding power sources and maximum weight capacities.

The Verdict!

A good thermoelectric cooler must be the perfect size to fit in your car and store drinks and food for your family or group of friends. The purchase, therefore, depends on many personal elements. However, if we summarize, here are the best choices of the moment…

  • For 2 or 3 people, the Wagan EL6214 model is worth it. The product allows food to be stored cold or hot. The structure is solid and the wide handle makes it easy to carry.
  • For a much larger format, we recommend the Dometic CFX 50W cooler which has a volume of 48 l, good power, and a lid that functions as two independent doors. The noise level is low.
  • Finally, the last model we have chosen is much more expensive because of the technology it contains. The F40C4TMP cooler is equipped with a compressor that allows you to precisely choose the internal temperature you want.
