Standard thermal bags only preserve cold metrics for less than an hour, while basic iceboxes demand frozen gel packs that hog valuable storage space inside. The Adler AD 8078 thermoelectric travel cooler, boasting a generous 28-liter capacity, is the perfect climate solution to break free from melting ice complications. Driven by an advanced solid-state Peltier element grid, it actively chills your provisions and can instantly switch cycles to keep warm dishes heated.

The appliance features a dual-power AC/DC infrastructure setup. This allows you to plug it directly into standard car cigarette lighter sockets (12V) during off-road overlanding, and easily shift to a residential wall outlet (230V) upon reaching a holiday cabin or campsite grid. Its spacious vault structure effortlessly accommodates family rations, including standing beverage bottles. The heavy-duty handle acts as an integrated structural lid lock to prevent accidental spills over rough terrains.

Key Features

Dual Cooling & Heating Matrix: Drops internal metrics up to 15 degrees below ambient room temperature or warms contents up to 55 degrees for total travel flexibility.

Spacious 28-Liter Vault Layout: Optimized vertical interior clearances enable smooth storage of large, upright grocery bottles and family meal prep boxes.

Hybrid 12V and 230V Connectivity: Ships with independent power lines for vehicular cigarette connections and standard household grids to ensure go-anywhere utility.

Integrated Handle Safety Lock: Ergonomic carrying handle doubles as a physical mechanism to securely clamp the lid down during heavy transit.

Eco-Friendly Silent Operation: Advanced freon-free thermal mechanics ensure low decibel operation while remaining completely safe for the environment.

Access to chilled drinks and the ability to take your favorite foods with you can make each closer or further trip pleasant. Regardless of whether we are going for a short picnic or a trip close to our residence, going for a weekend full of attractions, or a week of holidays, it is worth buying a portable cooler ADLER AD 8078. It is a perfect product for every travel enthusiast.

Large capacity and practical solutions

This type of cooler is an essential piece of equipment that will make every drive and trip pleasant. If we like to organize family trips outside the city, we often go on business trips and we cannot imagine the drive without our favorite drink or food, it is worth considering buying a portable cooler. In summer, the possibility of drinking cold water, a soda drink or tea, and the option of hiding food from high temperatures is worth its weight in gold. The capacity of 28 liters allows you to take with you more food for even a few people. A Peltier cell is used for cooling, which, thanks to its high durability and simple structure, is very often used in this type of cooling device. This is because it facilitates temperature control in the cooling chamber, regardless of the current-voltage. This is important because the set includes both a cable to connect the cooler to the cigarette lighter socket and a traditional socket. The thickness of the insulation inside the walls is 20-25 mm, which, combined with the special C5H10 cyclopentane insulation, allows you to maintain the selected temperature even for several hours.

Innovative features

To obtain the best effect, it is worth putting the previously cooled products into the cooler. So, it is better to leave them overnight in a home refrigerator and put them in a cooler just before leaving. However, what distinguishes our product from similar ones on the market is the combination of the cooling function with the heating function, which allows you to maintain a higher temperature of cooked dishes. The device will not heat the food, but it will keep your favorite soup or the main course warm longer. The constant temperature inside the device is about 16-20 degrees Celsius, more or less than the outside temperature (on average from -20 to +20 degrees). Thanks to this, the cooler will be useful even during trips in autumn or winter. It is a product that is applicable all year round. This is a big saving! Aesthetic design and solutions such as a removable cover and a comfortable handle will make us happy to take this fridge for every trip.
