Rating of the best portable cooler bags for 2021

For many people, the summer heat is often associated, among other things, with a variety of soft drinks and other chilled products. Far from stationary refrigerators operating from the network, during a country picnic, hiking trip or, for example, fishing, chilled products can be perfectly stored for a long time in a compact portable device called a refrigerator bag. Let's figure out how a cooler bag works and how it works, how long it keeps cold, and also what you need to pay attention to when buying it.

What is a cooler bag?

Essentially, a cooler bag is a fairly compact, portable container, often designed to look like a travel bag. Based on the principle of operation, such a container is similar to a thermos. Its design, as well as the materials of the case, prevent heat exchange with the external environment, due to which pre-cooled products placed in such a bag do not heat up for a relatively long time, even in hot conditions. These portable mini-refrigerators are usually used as storage for food and drinks, but sometimes they hold medicines and cosmetics.

Since the cooler bag has all the properties of a thermos, you can store not only chilled foods in it, but also keep dishes hot. Naturally, in this case, cold storage batteries will not be needed.

What is this - a cooler bag?

A cooler bag is a heat-insulated bag or container. In general, the expression “cooler bag” is used only by sellers and consumers of this household item; manufacturers call it exclusively as an isothermal bag. An insulated bag and a well-known refrigerator have only one thing in common - they are able to hold the cold. Only the bag, unlike the refrigerator, does not produce it, but uses the low temperature of the cold accumulator. The time during which the bag can keep food fresh is no more than 24 hours, then the temperature inside it will be equal to the ambient temperature.

Device

As already noted, in appearance this product most often looks like an ordinary travel cloth bag that can be worn on the shoulder. It often has additional external pockets and closes with a zipper. However, there are models made in the form of a backpack or a small plastic container with a carrying handle. All varieties of this product are equipped with an internal thermal insulation layer made of foil-coated thermal insulating material, for example, foamed polyurethane or foil-isolon. There are the following types of this product:

• simple cooler bags (also known as thermal bags or isothermal bags);
• thermal bags with a cold accumulator;
• devices that can produce cold on their own (usually they can be powered by a car's cigarette lighter) - some portable models that run from a car's cigarette lighter are refrigerator-freezers.

There are different types of cold accumulators.
Mostly there are bags made of durable film and flat plastic containers. If you keep such a product in the freezer and then place it in a cooler bag along with food, it will not only help them last longer in the heat, but will also lower their temperature - at least at first. It is advisable to put the products in the bag chilled. There are different types of cold accumulators. Mostly there are bags made of durable film and flat plastic containers. If you keep such a product in the freezer and then place it in a cooler bag along with food, it will not only help them last longer in the heat, but will also lower their temperature - at least at first. It is advisable to put the products in the bag chilled.

Principle of operation

Let's take a closer look at how a cooler bag works. Simple thermal bags retain cold solely due to the properties of the thermal insulation layer, which prevents heat exchange with the external environment. If such a bag is not opened too often, the food placed inside it will remain chilled for about three hours. Of course, this time depends on the quality of the product’s materials, as well as the quality of its assembly, and may vary between different models. In addition, this parameter is affected by the ambient temperature.

The principle of operation of a thermal bag with a cold accumulator is, in general, the same, but thanks to the use of this battery, such a product keeps the cold much longer. A good model can keep food refrigerated for up to 24 hours. The cold accumulator itself is a flat reservoir filled with a special solution or gel. It is first kept for several hours in the deep-freezing chamber of a stationary refrigerator, after which it is placed in a thermal bag. There, the battery gradually releases the accumulated cold, thus maintaining a low temperature inside the thermal bag.

Portable car mini-refrigerators, as a rule, can operate either from a car cigarette lighter or from a regular electrical outlet. They produce cold on their own, so they can constantly maintain the desired temperature. When disconnected from the power supply, they are able to keep food placed inside in a cool state for a long time, because... have good thermal insulation. Compared to thermal bags, this equipment is quite bulky and heavy, but if you compare it with stationary devices, car refrigerators are very compact (volume approximately 25-30 liters) and have a low weight (usually 4-5 kg).

bags

Physicists joke: heating is akin to creating a mess,

and cooling - general cleaning.

Making a mess is always
easier than cleaning up.
Unlike car refrigerators, which actually cool the food stored in them, thermal bags (or cooler bags) cannot do this. Their thick walls, sealed fasteners and reflective surfaces only diligently prevent the heat exchange of the contents with the external environment. And if the purchased bottle of drink was initially warm, then even in the best cooler bag the drink will only heat up even more. Cooling generators placed in the case, or so-called cold accumulators, will help to cool the food a little and keep it cool (see photo).

Types of cooler bags

There are different types of cooler bags available in the market these days. They differ not only in their design and appearance, but also in purpose. There are models designed for storing medicines, using cold accumulators, made in the form of a thermal container, etc. All these products are united by the ability to maintain the cold inside autonomously for a certain time.

For medicines

Products intended for storing medicines differ from ordinary ones in that they maintain the temperature exactly within a given range for a long time. For example, one of the models in the iCool Prestige line is capable of maintaining a temperature in the range from 2°C to 8°C for 24 hours at an ambient temperature of 24°C. Maintaining this temperature range is important for storing many types of medications, in particular insulin, various hormones, drugs for the treatment of polyarthritis, etc. In this case, the storage time should be enough to get to the right place and use the drugs there for their intended purpose or move them for storage in a stationary medical or home refrigerator.

Any thermal bag can be used as a regular shopping or travel bag, i.e. if necessary, fill it with any items

Travel refrigerator

These products are intended for use on hiking trips, outings and similar active activities. They are made from durable, wear-resistant and moisture-resistant materials. Travel cooler bags are lightweight and when folded they take up very little space. The set of all these qualities makes them very popular in many situations.

With cold accumulator

A cold accumulator is sometimes included in the delivery of a thermal bag, and sometimes purchased separately. In principle, this element can be used in any thermal bag. It can be installed in a regular place, or it can simply be placed in any suitable part of the thermal bag. The use of a cold accumulator significantly increases the efficiency of using a cooler bag, so it is always useful to have such an element in addition to the thermal bag itself.

On wheels

Car refrigerators, unlike other mobile isothermal units, are capable of producing cold independently. They are essentially portable electric refrigerators and require electricity to operate. Typically, equipment of this type can operate both from a 12 V vehicle network and from a standard electrical network. The device is connected to the car network through the cigarette lighter, to the standard one - through a regular socket. The installation itself of this type is a rigid structure in a plastic case with a carrying handle. It is often beneficial for car owners to choose just such a device, because... It is convenient to use when traveling to the country, and there are no problems with transporting a rather bulky product.

Refrigerator-thermos

The term “thermos refrigerator” refers to a small-sized thermal bag, the volume of which is designed to fit one one-and-a-half or two-liter bottle of mineral water or lemonade inside. The shape of the product corresponds to the shape of a standard bottle, i.e. is a tall cylinder. These models are very comfortable for long walks. A bottle of chilled drink placed there will remain cool for a long time.

Thermal container

A thermal container, or thermobox, is a container for storing chilled food. Unlike a thermal bag, this is a rigid plastic structure with an internal heat-protective layer. Fundamentally, this product is no different from a thermal bag; its operating principle is the same. The thermal container is closed not with a zipper, but with latches. For greater effect, a cooling cold accumulator can be placed inside such a container, in which case the product will maintain a low temperature longer.

How does the bag work?

Inside the thermal box there is a frozen salt solution, thanks to which the temperature in the refrigerator is maintained. The heat-insulating material is foil, which together with the solution maintains a constant temperature inside.

It's all about the sealed polyethylene foam on which the foil is attached, since it perfectly reflects and retains temperature. And it is supported by so-called salt solution batteries.

How to choose a cooler bag

Let's figure out how to choose a cooler bag. When choosing a suitable option, you should pay attention to such parameters and features as the internal volume of the product, the materials from which it is made, the availability of additional options and accessories. If you take into account all these nuances, you can choose the optimal model that best suits the user’s needs.

Capacity volume

The market offers cooler bags of various sizes, from small liter models to bulky travel bags and portable car refrigerators with a 30-liter chamber. The selection of a model of the required volume is carried out based on the tasks for which the purchased bag is intended. So, for a travel bag, an acceptable volume is 8-12 liters, while the volume of a car refrigerator can be 20-30 liters. If you plan to make country trips by car for several days, then you should think about using a thermal container with a volume of 50 liters or more.

Material of manufacture

As already mentioned, the internal thermal insulating layer of cooler bags is made of foil thermal insulating material. It can be foamed polyurethane, isolon or other material - they are all quite effective. The outer layer may vary. If you need a product made from woven materials, it is recommended to choose a model made of polyester, polyvinyl chloride (PVC) or nylon. These are good, wear-resistant and durable materials, thanks to which the purchase will last a long time. There are also hard plastic thermal containers. The plastic from which their cases are made has increased strength and usually does not cause any complaints.

In car refrigerators, the cooling system is usually not compressors, but Peltier elements. Such elements ensure the temperature in the refrigerator chamber is 15-30°C lower than the ambient temperature.

Cold accumulators for cooler bags

There are different types of cold storage batteries, differing in price and efficiency. They may be included with the product or purchased as separate items. You can purchase a certain number of these elements, for example, 2-3 pieces, and based on experience in using the bag, purchase (or not purchase) additional necessary elements. First, of course, it is better to consult with the seller. The following types of cold accumulators exist:

• saline - a saline solution in a container that can maintain a low temperature in the bag for up to a day;
• gel - they use a special gel and can maintain cold for up to several days (the indicator depends on external conditions, the quality of thermal insulation, the size of the bag, and the characteristics of its operation);
• silicone ones are also capable of maintaining low temperatures for up to several days, and within a rather narrow range.

Additional accessories for cooler bags

Often, cooler bags are additionally equipped with accessories; some accessories can be purchased separately. Thus, the delivery package of some models includes a picnic set, which fits in the additional compartment of the bag. The set usually consists of forks, spoons, spatulas, cutting board, etc. In addition, for an additional fee you can purchase accessories such as an antibacterial food mat, odor absorber, and ice packs.

Availability of belts and wheels

Many products made from woven materials, as well as some thermal containers, are equipped with belts. Thanks to such straps, cooler bags can be worn on the shoulder, so their presence is highly desirable. Backpack-type models also have shoulder straps (straps). The most voluminous bags can be equipped with built-in wheels, which makes them easier to move, although only on a flat surface.

Handles and locks

Plastic thermal containers, as well as car refrigerators, are usually equipped with folding handles for ease of transportation. Models with an internal volume of tens of liters may have two side handles, so that the heavy container can be carried by two people. Most models have a zipper as a lock. Thermal containers are usually equipped with latches. When purchasing, it is advisable to check the reliability of such a latch - not limit yourself to a visual inspection, but also try to open the lid secured by the latch without opening the latch itself. Of course, you shouldn’t make excessive efforts.

Cooler bag - how to choose?

A cooler bag or, as it is also called, an isothermal bag is a necessary thing for a family leading an active lifestyle. If you like trips to relax in nature, tourist trips in your own car, or you often have to go on long business trips by train, then you can’t do without a portable cooler bag! The thermal bag allows you to maintain the temperature required to preserve food cold, frozen or hot.

Choosing a cooler bag

Potential buyers need to know how to choose a cooler bag and what criteria to use when choosing.

Bag sizes

Small thermal bags are designed to carry just a few sandwiches or cans of drinks, their weight is from 400 g. It is convenient to put breakfast for a child or lunch for a spouse in this bag.

How to use

Using a regular thermal bag is very simple; just put chilled food or drinks in it and close it with a clasp. To increase the cold retention time, you can first keep this bag in the refrigerator for a couple of hours. If cold accumulators are used, it is necessary to keep these batteries in the freezer for several hours. The optimal holding time is usually indicated in the operating instructions. A car refrigerator is used in the same way as a regular one.

How to use a cooler bag?

A cooler bag is a portable device that allows you to maintain the desired temperature for a long time.
In terms of external design, household appliances are absolutely far from the usual kitchen appliances: the gadget is more like a portable bag, a kind of insulated container or a soft container. How to use a cooler bag? Very simple!
In short, the device works in a similar way to a regular thermos, but instead of retaining heat, it provides food at the temperature at which it was placed inside the device. For example, the owner of a refrigerator, having put not cold, but hot food and drinks there, will receive the same warm products when leaving. Producing cold and cooling food is impossible due to the technology of its creation and the peculiarities of its operation.

Before using the cooler bag, you should carefully read the rules of its use, characteristics and care features set out in the operating instructions for the thermal container.

To maximize the efficiency of your home appliances, you need to follow some basic rules. The specialists of our service center - we provide high-quality repair of refrigerators in Saratov at home - recommend:

• The portable device should be kept in a cool place - in an air-conditioned car or a shady place, and not carried separately with you;
• Repeated opening of an insulated container and frequent entry of warm air lead to a rapid increase in the temperature inside the container;
• A cooler bag is a kind of thermos; for this reason, food is pre-frozen and placed inside the bag already cooled;
• Tight and neat folding of provisions without free spaces increases the thermal insulation properties of the equipment.

Portable containers have a huge number of different models, differing in appearance (bag, travel bag, backpack), volume (from 2 to 50 liters), time to keep food warm (up to 30 hours), number of additional containers and methods of carrying (pull-out handles, shoulder straps , wheels).

You can contact our service center if the thermal device breaks down. In addition, our company’s specialists offer high-quality repairs of refrigerators from Atlant and other manufacturers.

How does a cooler bag work?

The positive effect of the operation of a conventional refrigerator is based on the fact that in the food storage chamber the temperature initially set and necessary for their preservation is maintained. Well, how does a cooler bag work? The manufacturer explains that inside it has the conditions to maintain optimal temperature. This device is helped in this by the foil that covers all the parts of the object, as well as the frozen saline solution, which plays a decisive role in maintaining the cold air in a constant state.

The way a cooler bag works can be compared to the functioning of a thermos, but in this case the opposite effect is created. For the manufacture of this device, high-quality and reliable thermal insulating materials are used, so the products are in excellent condition for several hours before they are used, so with such a unit you can move even long distances, carrying chilled food with you. A cooler bag will be useful if you choose a quality copy.

The secret to the proper operation of the thermal bag is very simple. Inside it there is a thermal box, the main material for the creation of which is foamed polyethylene, pre-sealed and glued. It is covered with an even layer of foil, therefore, in addition to tightness and resistance to temperature exchange with the environment, a reflective effect is also achieved. To maintain a constant cold temperature, batteries are used that operate using a saline solution. This explains how the cooler bag works.

How can you replace batteries in cooler bags?

Temperature accumulators can be made at home using improvised materials. The simplest temperature accumulator is a regular ice pack or a frozen plastic bottle of water. It is better to use a saline solution rather than pure water; it is more effective. This solution is prepared in the following proportion: three tablespoons of salt per 0.5 liters of water.

There is a more complicated recipe, it will require Glauber's salt and gelatin. Per liter of water use 200 grams of salt and 10 grams of gelatin. Gelatin can be replaced with wallpaper glue. First, salt is dissolved in water, then gelatin, which acts as a thickener. A battery with this composition is more efficient.

Another option for a cold accumulator is the use of granular filler for baby diapers. Granules from one diaper and two teaspoons of table salt are used for 250 ml of water. Let us describe the stages of the preparation process:

1. First you need to dissolve the salt in water.
2. Then the prepared solution must be carefully poured onto the inside of the diaper, so that all the liquid is absorbed into it.
3. Next, you will need to cut the diaper and remove the filling from it.
4. The extracted filler must be placed in a bag and kneaded with your hands. It is better to use a bag with a fastener, such as a Zip Lock.

Temperature accumulators condense moisture as they heat up. Therefore, it is better to wrap them in a cloth napkin - the fabric will absorb excess moisture.

Cooler bag parameters

Before choosing this item, you should determine in advance exactly how the food in it will be delivered to its destination. If the food will be in the car, you can take a bag with a volume of about 50 liters. It fits perfectly in a car and allows you to stow a lot of groceries, but it is almost impossible to lift and carry it or transport it on public transport. If you need to keep food fresh for a long time, you should choose items of large volume. The wider the bag, the more powerful the batteries are installed in it. This will allow you to understand how the cooler bag works.

Recommendations: how to keep food fresh longer in a cooler bag

The ability of a cooler bag to maintain a low internal temperature depends on a number of factors, namely:

• ambient temperature (the warmer it is outside, the faster the internal volume warms up);
• the quality of the bag itself, its thermal insulation layer, and the cold batteries used;
• how often the bag is opened.

The longer the low temperature inside the bag is maintained, the longer the food placed in it will remain fresh. To increase the cold retention period, you must adhere to the following recommendations:

• open the bag only when necessary and close it as quickly as possible;
• you can additionally wrap it in a blanket or clothes;
• place pre-chilled foods inside;
• Do not place the bag in direct sunlight.

Correct use of a cooler bag

Using a cooler bag on a trip or on a picnic is absolutely not difficult, since the operating rules are absolutely simple. But despite this, many either simply do not know about them or deliberately neglect them.

Although such a bag is called a refrigerator, it is not capable of cooling food, only keeping them at a certain temperature, like a thermos. Therefore, you need to put pre-chilled products in it, and for long-term storage - frozen ones, since, albeit slowly, heat gets inside and the frozen food melts.

When opening and closing the bag, it is important to let in as little heat as possible, that is, do it all as quickly as possible. In order for the effect to last as long as possible, it is not recommended to wear the bag separately from other things. It’s better to let it be wrapped in some kind of blanket or placed in the trunk.

There are bags that do not include special cold accumulators, but thanks to them it would be possible to improve the thermal insulation of the refrigerator. It’s convenient that you can make them yourself. Simply fill several bottles with well-salted water, freeze them in the freezer, and place them in a bag between tightly packed foods. If there are empty spaces left, it is recommended to fill them with paper.

If you strictly follow all operating rules, a cooler bag can keep food fresh for about 5 days.

How to make a cooler bag with your own hands

A thermal bag is a fairly simple product, and if desired, you can make it yourself, at home. If you have all the necessary materials, this process will not take much time. In this case, cutting skills are desirable, but not required. Let's figure out how to make a cooler bag with your own hands.

First you need to choose a bag that will be turned into a thermal bag. A road or sports model with a zipper, made of polyester, PVC or nylon, is suitable for this. The fabric should be dense. For the heat-insulating layer, it is best to use foil-isolon - this is a foiled synthetic material with excellent thermal insulation properties. In addition, you will need foil tape and foam rubber (it can be replaced with padding polyester). Let us describe the manufacturing stages.

1. First you need to measure the bag from the inside.
2. Based on the measurement results, draw patterns and transfer them to foil-isolon. When transferring, it is necessary to slightly reduce the resulting dimensions, by about 1 cm - this is necessary so that the cut sheets of thermal insulation fit freely inside the bag. For the lid, on the contrary, make an overlap of about 3 cm; when closing the lid, the protruding material will be tucked inside.
3. Cut out all marked parts of the insulation.
4. Connect the edges of the cut out parts with threads and seal the inside with foil tape.
5. Insert the resulting heat-insulating layer inside the bag. Fill the space between the thermal insulation and the outer layer with foam rubber.

What is a cooler bag for?

The scope of use of an isothermal bag is extremely wide. Think for yourself:

• You can make large purchases of products without worrying about their safety. Even while walking around the market for half a day on a hot July day, you can be absolutely calm about the freshness of the purchased meat or dairy products if you carry them in a thermal bag with cold batteries;
• You can take cold drinks, ice cream and other foods with you to the beach;
• You can store necessary cosmetics and medicines in a thermal bag that cannot be kept outside the refrigerator;
• You can take perishable food with you on a long trip (out into nature, to the sea, to the country, on a camping trip);
• You can keep baked goods or other dishes and drinks warm, even if you have an outing or a country picnic;
• You can take your lunch to work, school, or training in a small thermal container;
• You can calmly wait out an unexpected power outage, repair or defrosting of the refrigerator without losing food from the freezer;
• You can store your fishing catch or meat obtained from hunting in a thermal bag.

Some prudent housewives acquire several thermal bags of different sizes for different needs. In a word, all you have to do is buy or make a cooler bag with your own hands, and believe me, you won’t have it sitting idle!

Working principle of the cooler bag

The principle of operation of a cooler bag can be compared to a thermos.

→ The main factor ensuring the maintenance of the required temperature is its high thermal conductivity. The product can maintain a temperature in the range of 10-18°C below the external temperature, but not lower than + 3°C.

→ In addition to keeping you cold, this bag can also keep you warm. If there is a need to store, for example, hot dishes, the bag is used without cold accumulators.

→ How cold a refrigerator bag keeps depends on its characteristics.

The validity period of such a bag is from 5 to 24 hours and directly depends on several indicators:

• From the air temperature - the warmer it is outside, the shorter the time it takes to maintain the desired temperature;
• From the size - the cooler bag can hold both 1 liter and 50 liters. The larger the volume, the longer the internal climate lasts;
• Depending on the condition of the food contained - if it is frozen, its shelf life is much longer than when the food is kept chilled or hot.

Cooling elements or cold accumulators

The main function of maintaining the cold temperature is performed by frozen cold cells or cold accumulators . The guaranteed service life of the cold elements is up to 5 years . Therefore, after the batteries wear out, they can be purchased separately. As a rule, special containers are used as cold elements. These are plastic briquettes filled with a heat-intensive saline solution. There are gel cold accumulators. In terms of price they are almost the same. The lifespan of the bag itself is up to 30 years . At least that's what some manufacturers say.

Instead of containers with cold-forming filler, reusable ice can be used for the same purpose. Techniice™ offers it very widely . According to functional indicators, one pallet of such ice replaces 5 cold elements. In general, there is a choice. The cost of one cold storage battery is about 60 rubles. Reusable ice will be cheaper.

The refrigerator bag with the cold accumulator is ready for transportation in about half an hour. It is after this time that the required temperature will be inside. But some manufacturers offer already frozen cold elements along with thermal products. Only the price will be 100-1000 rubles higher, depending on the volume of the container.

What is different about a car bag?

The question often arises, what are the differences between a portable refrigerator bag and a car bag. The difference is that the cooling principle in the first case operates only due to the low temperatures of the frozen cold elements. And in the second case, the cold accumulator operates electrically from the car’s cigarette lighter. The bag differs from a thermal container only in its possible volume and material of manufacture.

In the huge range of thermal products, you can also choose a very small thermal bag for bottles with a capacity of 1 liter. It is ideal for everyday use, for example at work. In hot weather, you can fit a bottle of drink there, which will remain cool throughout the working day.

The most popular manufacturers and models of cooler bags

• Campingaz Ulimate 25L – 2500 rubles;
• Thermos American 12L – 760 rubles;
• Thermos K2, 44L – 1300 rubles;
• Campingaz fold Cjjl Classic 20L - 785 rubles;
• Time Eco TE 311S, 11L – 400 rubles;
• Coleman 24 can cooler Gray – 1650 rubles;
• Gio Style Silk 35 I – 2100 rubles.

As you can see, there are a huge number of different refrigerator bags. And, before you make your choice, you need to clearly define for what purposes you need it.

Since the bags are intended for food , only high-quality materials that comply with food storage standards should be used in production. As a rule, this data is written in the bag's passport. When purchasing, it is advisable to familiarize yourself with the production document to be completely sure that you are purchasing a truly high-quality item and not a fake.

You already know the main fundamental differences between one type of thermal product and another, so it will be easy to make the right choice.
