Best Thermoelectric Cooler Boxes

The brand Camry mostly offers inexpensive household appliances. The company's portfolio also includes some interesting offerings for motorists, specifically the CR 8065 travel refrigerator.

The model is designed in the form of a plastic box with a convenient flip-up lid. The fridge has a 24-liter capacity and excellent thermal insulation. It maintains a constant temperature with a variance of up to 20 °C relative to the outside temperature. The auto-refrigerator is intended for cooling drinks and food or keeping warm food at a temperature of around 60 – 65 °C in heating mode.

The Camry CR 8065 belongs to the segment of thermoelectric auto-refrigerators, which operate on the Peltier effect. Special semiconductor plates heat on one side and cool on the other when electric current is passed through them. By changing the polarity of the electric current, the device's operation modes for cooling or heating are switched.

The refrigerator draws power from a car cigarette lighter socket (12 V), and during stops, it can be connected to a standard household socket with a voltage of 230 V. The model is convenient to use, thanks to a removable divider for sorting products inside the working chamber. With dimensions of 45x30x44 cm, the auto-refrigerator weighs around 4.2 kg.

The Adler AD 8078 container-fridge uses a thermoelectric principle based on Peltier plates and improved cyclopentane insulation (20-25 mm thick), which guarantees longer temperature retention when the device is turned off. The material also stands out for its environmental friendliness due to the absence of harmful emissions into the atmosphere and ensures product safety during operation. The equipment functions in both heating mode and cooling. A fan provides even air distribution. The internal microclimate changes by 20 °C relative to the surrounding environment, which is an optimal indicator. The lid features a folding handle for carrying.

The thermal box is targeted for car trips to leisure destinations (beach, picnics, camping, fishing, hunting) and can hold cooling drinks for a large company — 44 cans of 0.33 ml each. It is also suitable for transporting groceries from the store, medicines, and supplies during business trips. The device connects to the car’s onboard network (12 V) through the cigarette lighter socket and supports power from a 230 V outlet, expanding its application at home. All electronics are located in the lid, which can be removed, making it easy to clean the container. The balanced thermoelectric box is distinguished by its affordable price.

The practical Sencor SCM 3224BL model is suitable for use in car travels at any time of year. The portable refrigerator operates in two main modes — cooling and maintaining warmth.

The device is a spacious plastic box with an internal usable volume of 24 liters. With the lid closed, the container can easily fit 6 plastic bottles of 1.5 liters or 5 bottles of 2 liters each. When it comes to food, the fridge chamber can hold sufficient provisions for a company of 3-4 people. The removable partition allows for separating incompatible foods.

The model can cool the contents to a temperature 16–18 °C below the ambient temperature. A green lamp near the "HOT/COLD" slider switch indicates device operation in cooling mode, while a red lamp indicates heating. Also, the Sencor SCM 3224BL boasts an economical ECO mode from the 230 V network — when activated, cooling automatically turns off upon reaching 12 °C. In the car, the refrigerator is powered from the cigarette lighter socket.

The container uses a car battery discharge protection system to prevent unpleasant situations associated with deep battery discharge. Other notable features include 3 practical pockets in front and on the sides of the refrigerator's body, a large handle for easy carrying, and a dual closure system to prevent spoilage. The only drawback compared to peers is the significant weight (around 8 kg).

The compact and light NEO 63-152 auto-refrigerator container is positioned as a universal 2-in-1 solution. The model can operate both for cooling and heating.

The 26-liter container holds enough supplies for a company of 3 – 4 people. The fridge also has space for 5 – 6 one-and-a-half-liter bottles of drinking water. In the car, the device is powered from the 12 V cigarette lighter socket, while outside the vehicle, it can connect to a standard 230 V household network.

The model relies on Peltier thermoelectric elements. When current passes through them, the outer side of the plates heats and the inner side cools, thus maintaining a low temperature. By reversing the current direction, the inner sides of the plates warm up, activating the heating mode. Temperature control inside the container is possible through the data on a small info-display built into the top lid.

The connection panel of the auto-refrigerator includes AC DC sockets for cigarette lighter power, DC for household network power, and a USB port for charging mobile gadgets conveniently. The USB port will be a lifesaver when the car cigarette lighter socket is busy and will help keep mobile devices charged on the road.

The compact Pinnacle Power auto-refrigerator with Indian roots in its genealogy provides indefinitely long maintenance of cold or heat. The main condition for this is connecting the device to the car's 12 V or standard 230 V power network.

The refrigerator is built into a shockproof plastic body of an unusual turquoise color. The body walls are filled with thermal insulation material — polyurethane foam. Semiconducting plates, operating based on the Peltier effect, are integrated into the aggregate's front wall. When the current flows through them in one direction, the inner plate cools, and when the electron flow changes, it heats up. Thus, the device's operation modes for cooling and heating are ensured.

Before a car trip, it is recommended to cool products and drinks in a household refrigerator. Another option is cooling the auto-refrigerator chamber using coolant batteries. It's important to remember that the device doesn't cool products but keeps them cold at a consistent temperature (approximately 15 °C below outdoor temperature). In heating mode, the inside of the box can maintain a temperature of up to 50 °C.

As for the refrigerator's capacity, it easily fits 4 two-liter plastic bottles of drinking liquid. The overall useful working chamber volume is 30 liters. For easy access to contents, the lid of the model is fully removable. Lastly, it is worth noting the increased power of the device during connection to a household outlet — cooling and heat generation in this power variant almost doubles compared to powering the auto-refrigerator from the cigarette lighter socket.
