What is a cool box?
A cool box, known as an ice box, is a type of mobile refrigerator . Such a box allows you to cool food on the go. For a short period of time, there is the option of preventing frozen food from thawing. In addition to food, drinks and other things that require cooling can be stored in a cool box. This is why cool boxes are used, for example, when transporting medication. Even organs for a transplant are kept in a cool box during transport. Accordingly, these boxes are used in the following areas of life:
- Leisure time – for example when camping
- Sport – for example when fishing
- To travel
- In the household – for example as a temporary replacement for a defective refrigerator
- In health care
So that the cool box can keep the lowest possible temperature inside, it has special insulation . Nevertheless, the penetration of heat cannot be completely avoided. Accordingly, appropriate technologies are required to prevent the temperature inside the cool box from rising too high. Basically, this can be a passive or an active cooling technology.
A crucial disadvantage is that passive cool boxes only cool your food for a limited time. Sooner or later, the ice cubes or ice packs will inevitably thaw and must therefore be replaced. If you then have no replacement at hand, you can no longer adequately cool your food. This problem can be avoided with an active cool box. You are faced with significantly more options when it comes to active coolers. After all, you can choose an absorber cooler, a cooler with a compressor or a Peltier cooler. Various manufacturers offer hybrid coolers that use both compressor and Peltier technology.
The advantages and disadvantages of different types of active cool boxes
Whether a compressor, absorber or a Peltier cool box is the right choice for you is both a question of the budget and the intended use. If you want to transport frozen food over a longer period of time, you will usually choose a compressor cooler. These cool boxes offer the highest performance, so that freezing temperatures can be easily reached .
Although you should be prepared for comparatively high purchase costs , these boxes are hard to beat in terms of their capacity and cooling capacity. At the same time, it should be borne in mind that a compressor cooler is characterized by a rather loud operating noise from the compressor. So why buy a cooler with a compressor anyway? Before buying a compressor cooler for travel or your car, do a good job of weighing up the following advantages and disadvantages:
If you decide against a compressor and an absorber cooler, the energy supply of this mobile refrigerator can be done in three ways. In addition to a 12 and 230 volt connection, there are absorber coolers that can be operated with gas. A gas cooler is particularly suitable as a camping cooler, since many campers use gas for cooking anyway.
These cool boxes attract attention with their convincing cooling performance, as temperature differences of up to 25 degrees Celsius are possible compared to the ambient temperature. A gas cooler is significantly quieter than a model with a compressor. This is an advantage when camping at night. Hotel minibars often use this cooling technology in view of the quiet operation.
Given the temperature difference that an absorber cooler can achieve compared to the environment, this model is suitable for use at up to 30 degrees Celsius . With higher outside temperatures it is no longer ensured that your perishable food stays sufficiently cool. This limits the possible uses for an absorber cooler. So weigh these advantages and disadvantages before buying:
What is a thermoelectric cool box ? A thermoelectric cool box is known as a Peltier cool box. Such an electric cooler is often available not only with a 12-volt but also with a 230-volt connection. You have the choice whether you want to operate the device as a cooler for the car via the cigarette lighter or using a regular socket. The low weight of these cool boxes speaks for itself. In addition, the prices are comparatively low.
However, the price savings go hand in hand with a moderate cooling capacity that cannot compete with a compressor cooler or an absorber cooler. You should be informed about the high power consumption , as this increases the follow-up costs for the operation of the cool box. The fan, which has a thermoelectric cooler, is loud, which may prevent you as a prospective buyer from opting for such a car refrigerator. To make your purchase decision easier, a comparison of the main advantages and disadvantages of this device type follows:
In conclusion, the hybrid coolers should be said that they are also relatively cheap to buy. Compared to a pure Peltier cool box, however, the hybrid model scores with better cooling performance.
Which is better – a cool box or a cool bag?
It is not possible to answer this question across the board. However, you will find a practical decision-making aid below. If you want the most compact and flexible form of cooling for your food , a cooler bag will probably appeal to you. A cool bag has a significantly lower weight than a heavy cool box. However, the cooler bag is inferior in terms of cooling performance. The reason for this is that passive cooling can always be assumed for a cooler bag. The insulation is usually not as efficient as that of a cool box. A cooler bag is therefore particularly suitable for transporting your food and drinks over short distances and for a short cooling period.
Cooling bags are not only suitable for the transport of frozen food from the supermarket to your home. If you are planning an excursion, drinks, pasta salad, herb butter, etc. can be stored in a handy cooler bag. You may be carrying your yogurt or other breakfast treats to your workplace with such a bag. A cool box, on the other hand, is useful if you want to reliably benefit from better cooling performance.
For longer journeys by car, a cool box, which you can operate using your vehicle’s cigarette lighter, can be useful. By choosing a box with active cooling, your food stays chilled longer. The longer cooling time and the larger capacity as well as the possibility to reach lower temperatures and even minus degrees speak for an electric cool box. However, such a box cannot compete with the light weight of the cooler bag.
If you don’t want to struggle with the heavy weight of this mobile refrigerator, consider buying a cooler with wheels . Keep in mind that the cool box has a rigid shape, while a cool bag is flexible and pliable. This may mean that you may have problems placing a particularly bulky cool box in your vehicle. Before buying, you should therefore take a look at the dimensions of your desired product.
Which cool box to buy? Practical tips for your selection
In view of the many options and the different technologies, there is hardly any way around a cool box comparison. Your personal life circumstances, your budget and your preferences should be the focus of your research. In addition, there are a number of quality criteria that apply when buying most cool boxes . Use this list to get an overview:
- The dimensions
- The maximum net capacity in liters
- Active or passive cooling
- The weight
- The energy efficiency class for models with electricity
- The cooling system with active cooling
- The cooling time with passive cooling
- The design
- The effort for care and maintenance
- The insulation
- The brand and its reputation
- The connections
- The operating costs for electric or gas powered coolers
- Transport rollers
- The material
- The scope of delivery
- The length of the guarantee period
- Repair service from the manufacturer – especially important for very expensive boxes from the high-end segment
Energy efficiency is particularly important if you want to use your cool box for a longer period of time. This can be the case not only when camping, but for example when your kitchen is being renovated and you have to do without a conventional refrigerator. However, not all manufacturers state this value. The simple reason is that many cool boxes are only used for short distances and short periods, such as a day trip. In such a scenario, energy efficiency is indeed negligible.
With regard to the dimensions of your new cool box, you should not only check to what extent it can be conveniently accommodated in your car, truck or camper. Rather, many cool boxes have ventilation slots, from which a minimum distance specified by the manufacturer must be observed.You have to plan this space if you do not want to risk that your cooler overheats and can be irreparably damaged. Weight matters. If you want the lightest possible cool box, you will choose a simple, passive model made of polystyrene. Compressor coolers weigh the most, which is why it makes sense for such a heavy device to pay attention to transport rollers when buying it. However, this considerably restricts your selection, since transport rollers are not among the common standard features of such boxes.
With regard to the useful content, it is better not just to keep an eye on the total capacity. The height of the interior of the cool box should be decisive for the purchase . This value is the only way to determine which bottles fit upright in your cool box. When buying a passive cool box, it should be borne in mind that you cannot use the entire interior of the box for your food. Plan enough space for the ice packs or ice cubes to cool your food and drinks.
A look at independent judgments such as those of the Stiftung Warentest or Öko Test cannot hurt either. You can find more information on this at the end of this guide. Also keep an eye on real customer reviews for your coolbox favorites. This makes the cool box comparison a lot easier for you, since you can find out more about cleaning, handling and user-friendliness, as well as the build quality and durability of the different boxes.

Rather, the takeover by the American company Coleman took place in 1996. Coleman can look back on a long company history that began in 1900. SEVERIN has been in business for even longer, since 1892. you will be interested in the cool boxes of this company. As you can see, it can make sense as part of your purchase decision to find out more about the different brands.
Frequently asked questions
Which cool box is recommended for the car?
If you want to buy a car cooler or cooler bag, how long do you want to cool your food and drinks? A passive cool box is usually sufficient for short journeys. For longer distances, you should opt for a cool box with a 12 volt connection. At the same time, the cool box should work as energy-saving as possible, so as not to damage the car battery of your vehicle too much. Consider the dimensions of your new car cooler. A small cool box is much easier to store in most vehicles than an XXL model.
After all, you have to place the cooler inside the vehicle near the cigarette lighter, as the cable length is limited and the power connection is essential for cooling. Whether absorber, compressor or thermoelectric cool box, all these boxes are available with a suitable connection for power operation in the car. Ultimately, your budget and your preferences as well as your requirements decide which model it should be for you. It is best to refer to the previous list of advantages and disadvantages of these three types when making your decision.
How long will my food stay cold in my cool box?
The longer your mobile cooler cools your food and drinks, the more flexibly you can use them. The exact cooling time is difficult to determine because it depends on a variety of factors. The cooling time of a passive cool box is in most models a maximum of 12 hours. The more batteries or ice you put in the box, the better the cooling time will be. At the same time, this limits the available storage space for the food to be cooled.
If you have chosen a cool box that can be operated via an electrical power source, this can offer you an unlimited cooling capacity. Only when using the cigarette lighter in your vehicle will you be faced with the restriction that your car battery will eventually be exhausted due to the continuous operation. The same applies to the batteries of battery-operated coolers.
As soon as your electric cooler is no longer supplied with power or you use a passive cooler, the outside temperatures play a role. In freezing winter temperatures, the ice box will keep your food cool significantly longer than if you set up the mobile refrigerator at 30 degrees Celsius in the blazing sun. The more you open the box, the more heat can get inside. Therefore, keep the cool box closed as far as possible and only open it when absolutely necessary. This is how your food stays cold the longest.
How much electricity does a cool box use?
The consumption of a mobile refrigerator is one of the values that you should take into account when comparing your cooler. The consumption depends on the following factors:
- Insulation because better insulation reduces cold loss and consumption
- The size of the box because the consumption increases proportionally compared to the size
- The outside temperature, since a higher ambient temperature means a higher energy expenditure for cooling the food
- The temperature of the refrigerated goods – the warmer the food and drinks are, the more they have to be cooled, which means higher consumption
- The operating time
A look at this list shows why it is difficult to provide general information on consumption. You can assume that a stationary refrigerator is more energy efficient than a cool box. This means that you should do well to put refrigerated goods in your cool box instead of filling them with lukewarm food and drinks.
With an electric cooler, pay attention to a high energy efficiency class. For electrical devices, the energy consumption depends on the power in watts and the operating time. When using an absorber cooler with gas, you can expect an approximate consumption value of 10 to 25 grams of gas per hour.
Thanks to this data, you can calculate the operating time for which your gas cartridge will approximately suffice. Regarding the use of cold packs with passive cool boxes, it should be said that it will take a maximum of 10 to 15 hours until the batteries have warmed up too much to cool your food well enough.
Which gas is required for a gas cooler?
Most absorber coolers can be operated with a compact gas cartridge or with a gas bottle with propane gas. A distinction is made between the following variants of gas cartridges:
- MSF-1a valve cartridges
- Screw cartridges
You will need an adapter to use a valve cartridge, as this cartridge has no thread. The adapter turns the valve cartridge into a screw cartridge. Don’t be surprised if the valve opens as soon as you screw the adapter onto the cartridge. This is wanted because the adapter has its own valve. You also need a regulator that you can connect to the gas hose of your cool box. Such a cartridge regulator is required for a screw-in cartridge.
This regulator is required because gas cartridges have a smaller thread than the gas hose of the common absorber coolers. You need adapters and controllers when using a plug-in cartridge. If you want to connect a gas cartridge with as few accessories as possible to your absorber cooler, you can use a screw-in cartridge for which you do not need an adapter.
What are cool boxes in English called?
The following terms are common for cool boxes in English:
- Cold box
- Cooling box
- Ice box
- Portable ice chest
How long have there been cool boxes?
The invention of the first cool box goes back to an American named Richard C. Laramy. He was able to shine with this brilliant brainstorm in Illinois in 1951. The patent for this invention was later transferred to the Coleman Company. An important innovation followed in 1954, since the production of coolers now relied on galvanized outer casings. Just 3 years later, plastic covers for mobile refrigerators have become established. Whether fishing, hiking, grilling or camping, cool boxes have long since started their international triumph.
Which cool box is recommended for camping?
When camping, it can sometimes be assumed that you have no or only limited access to an electrical outlet. If you are traveling in sunny regions, a solar cooler can be worthwhile. Keep in mind that this cool box needs a lot of energy to achieve the desired cooling performance due to the high outside temperatures. Therefore it can happen that the solar charge is not sufficient. You are on the safe side with an absorber cooler with gas. If you carry enough gas with you, you can ensure that your food stays cool enough in the great outdoors during your camping trip.
