Introduction: More than just a cooler bag
A Foursun coolers are a serious step up from traditional ice pack solutions. When we go camping, fishing or just taking a long car trip for several days, storing food at the right temperature is always a critical point. Traditional passive coolers only slow down the warming, but are not able to actively cool it, and the ice melts over time, soaking the food inside. Devices equipped with compressor technology eliminate this practical problem.
With Foursun coolers, there is no need to compromise on cooling performance. Since they have a built-in compressor, they work exactly like your home refrigerator, but in a portable form. This means they can cool the interior down to -20°C, making them suitable not only for keeping drinks cold, but also for safely transporting meat, frozen products or ice cream.
Efficient compressor cooling in practice
The most important parameters of portable coolers are cooling speed and stability. The high-efficiency compressor of Foursun coolers ensures rapid temperature reduction. If you put a jug of warm mineral water in the summer heat, the device will cool it to a comfortable temperature in a short time. The system uses environmentally friendly R600a refrigerant, which is also common in home appliances, ensuring reliable and efficient heat dissipation.
Polyurethane foam insulation plays a key role in Foursun coolers maintaining their internal temperature for a long time after being turned off. This is especially useful when you take the cooler out of the car and take it to the beach or to the tent and temporarily unplug it. The thick insulation also means the compressor has to work less, which reduces energy consumption.
Smart control: Tuya Smart app
Technological advances have also reached camping equipment. Foursun coolers have a built-in Bluetooth module, so they can be connected to a smartphone. Via the Tuya Smart application, we can remotely check and adjust the temperature without having to get up from the campfire or open the trunk while driving.
This feature is not just a convenience. For example, if you are transporting sensitive food (e.g. fresh meat), you can use the app to continuously monitor the interior temperature. If you see that the interior of your car is getting hotter than it should be in the sun, you can immediately lower the target value or switch to maximum cooling power from your phone.
Power supply for all situations and ECO mode
The usability of a portable cooler largely depends on the power source it can be powered from. When designing the Foursun coolers, the manufacturer has thought of every eventuality. With the included cables, the device can be connected to a standard 230V wall socket (for home pre-cooling), as well as to a 12V and 24V cigarette lighter, which allows it to be used in both cars and trucks.
In addition, the system is compatible with portable power stations and solar panels, which is especially important for wild campers. If you want to save battery power, the Foursun coolers can be set to ECO mode. In this mode, the daily energy consumption is only 0.18 kWh, which is an extremely low value. This means that it can operate for days from an average portable battery station without having to worry about running out of power.
Design, portability and size options
Since the weight of a packed cooler can be significant, portability is essential. Foursun coolers feature a robust, wheeled design. The built-in, smooth-rolling wheels and sturdy handle allow the unit to be pulled like a suitcase. This is a huge help when you need to get your gear from the parking lot to the picnic area.
The cup holders on the outer casing are small but useful accessories. When using the cooler as a side table next to the tent, drinks stand firmly on top. Foursun coolers are available in three different capacities, so everyone can find one that suits their needs. The 35-liter model (14.5 kg) is ideal for weekend getaways, the 45-liter (15.4 kg) serves the needs of an average family for several days, while the 55-liter version (16.2 kg) offers more serious storage capacity for long-distance hikers or truck drivers.
Who do we recommend the Foursun coolers use?
These devices are primarily designed for those who regularly spend extended periods of time outdoors or on the road and are not satisfied with compromise solutions. Foursun coolers are an excellent service for anglers, who can keep food fresh during day-long trips, and can even freeze caught and cleaned fish until the trip home.
It is almost a must-have for campers and motorhomes, as its low consumption and solar/battery compatibility allow it to operate reliably even without mains power. It is also a rational choice for professional drivers and truckers, as it functions as a full-fledged refrigerator in the cab thanks to the support of the 24V system. Finally, families heading to a holiday home or weekend house can also benefit from it, as it protects perishable food brought from home from warming up during the journey.

Frequently asked questions about Foursun coolers in connection with
Q: How long does it take to cool to the desired temperature?
A: Thanks to the built-in high-performance compressor, Foursun coolers can cool from room temperature to around 0 degrees Celsius when empty, quickly, in as little as 30-40 minutes. It takes a little longer to reach the full -20°C, depending on the ambient temperature.
Q: Does it work from a regular outlet or only from a car?
A: Yes, the package includes a European power adapter, so it can be operated from a 230V network (100-240V AC) at home, in the summer cottage or at the campsite without any problems.
Q: What gas does the refrigeration system use?
A: Foursun coolers use the modern, environmentally friendly refrigerant R600a. It has excellent thermodynamic properties, resulting in fast and efficient cooling.
Q: Can it be used with solar panels or a portable battery when wild camping?
A: Yes, thanks to the standard connectors and low consumption (only 0.18 kWh/day in ECO mode), the cooler can be operated without any problems from portable power stations and connected solar panels.
Q: What app do I need to download for phone control?
A: The devices are compatible with the Tuya Smart app, which is available for free download on both iOS and Android platforms. Through it, you can change the settings remotely.
Q: Will the wheels handle the terrain if I'm not pulling on concrete?
A: Foursun cooler wheels are designed to make moving them easier on grass, a packed dirt road, or a gravel camping area, so you don't have to constantly carry the heavy, packed box.
Q: What exactly is included in the box when purchased?
A: The package includes the cooler itself, a European plug power adapter with cable, a 12V/24V car cigarette lighter cable, and a detailed user manual.
Q: What is the difference between the three available sizes?
A: The 35, 45 and 55 litre Foursun coolers have the same footprint (691 x 390 mm) and therefore occupy the same amount of space horizontally in the boot of your car. The difference is in their height (440 mm, 510 mm, 580 mm) and weight (14.5 kg, 15.4 kg, 16.2 kg).
Q: Can the same cable be used in both a car and a truck?
A: Yes, the included DC cable automatically handles both 12V (general passenger car) and 24V (truck, lorry) systems without the need for a separate converter.
Q: If I turn it off or there is a power outage, how long will the interior stay cold?
A: Thanks to the thick polyurethane foam insulation, Foursun coolers have excellent heat retention capabilities. Although the exact time depends on the outside temperature, the food inside will remain safely cold for hours after the power is cut off, as long as the door is kept closed.
