Type: the first thing to decide is what kind of travel fridge we want. The most common options are folding portable refrigerators (bag or backpack type), electric portable refrigerators (capable not only of conserving temperature but also generating cold), and rigid portable refrigerators (chest or trunk type, but within the category of portable refrigerators without electricity ).

Power source: if we have opted to buy an electric travel fridge, it will be necessary to take into account if it is plugged into the power outlet, if it is connected to the car cigarette lighter or if it includes a rechargeable battery.
Size: it is an issue that must be assessed for 2 fundamental reasons. The first one is that the size will determine the capacity of our new camping fridge, and the second because its dimensions will determine how easy or difficult it will be to carry it from one place to another, either carrying it or in the trunk of the car.
Temperature: travel refrigerators without electricity, that is, those of a lifetime, are limited to maintaining the temperature of our food and beverages, and require the use of ice or cold accumulators to cool them for a limited period of time. However, electric travel refrigerators are capable of generating cold by themselves, so it is advisable to find out what range of temperatures they can reach (it is usually between 15 and 25 degrees below room temperature).
