Shopping guide 


A cooler is one of the most loved electrical appliances by drivers looking to keep cold drinks within reach during their travels. It is ideal to take to the mountains, the beach and in general anywhere you travel. However, the wide variety of models that the market offers makes your choice a bit more complicated than you think.

That is why we have made the decision to create this practical guide to buying the best car fridge so you can choose the model that best suits your needs.


Type of fridge

In any comparison of car refrigerators, there is one main aspect that you should look at before making a light choice, and that is that distinguishing the type of refrigerator you are looking for is vital for you to acquire a device that is functional for your needs.

The market offers a wide variety of models to choose from, some only cool and some also heat your interior.

For this reason, it is important to know what type of food or drink you are going to take on your trip and if it needs to be kept cold or hot. The best refrigerators perform both functions, so they have a small switch with which you can change from cold to hot quickly. This gives them a great advantage thanks to their versatility.

However, if you are concerned about how much it costs, it is important to know that the more features the device provides, the more expensive it will cost you.



If you are looking for a good and inexpensive car fridge, then it is very important that you look at the power that the device provides, since, the more power it offers, logically it will cost a little more.

In these devices, the power is known as watts and this can vary greatly from one model to another. Therefore, if you are looking for a refrigerator that properly cools the interior and food, it is vital that it has a good power.

As with the heating function, this characteristic will define how hot the inside of the device can get. However, remember that the higher the power, the greater the noise emitted by the motor and the fans, so it is advisable to also take care of this aspect.


Temperature reaching

Another aspect that you should take care of, especially if you are concerned about keeping food in the fridge at a certain temperature is the level of cold or heat that the device manages to generate.

It is common in these devices that the level of cold or heat is determined by the ambient temperature, managing to reduce or raise the internal temperature a few degrees from the external temperature.

This is why most of these devices indicate that they can cool up to 15 degrees below room temperature. This means that if the street is 29 degrees, the interior may be 14 degrees. On the other hand, if the instruction manual states that the refrigerator raises the temperature up to 5 degrees, it means that the 29 degrees of the environment are added the 5 of the interior, resulting in 34 degrees.



Although it is one of the aspects that goes unnoticed the most when making a decision about which is the best refrigerator, very few users really pay attention to it. However, they are far from believing that it is a useless factor to look at, since the design is directly linked to the size and weight of the refrigerator, as well as to the ergonomics and ease of use that the device offers.

First of all, it is important to ensure that the refrigerator can fit perfectly in your vehicle without any problem, but that it also has the possibility of entering the amount of food and drinks you want. There are even models that include a separating grid with which you can better organize the inside of the fridge.

In addition, we recommend that you check if the appliance incorporates a handle system that makes it easier to load it, as well as wheels that provide the possibility of moving the refrigerator comfortably when it is heavily loaded and thus avoid having to lift it.



Finally, another of the technical characteristics that distinguish one car fridge from another is its storage capacity. The alternatives range from compact models with storage of up to 6 liters to gimmicky and spacious refrigerators that can fit up to 30 liters. So, depending on the amount of food and drinks you want to take on your trip, choosing a model with enough content space is key.
