Cool boxes

Whether camping, on a picnic, a day trip, or in the garden – coolers ensure that drinks and food stay pleasantly cool and fresh even without a fridge. They are available in various sizes and versions and offer the right solution for every situation. Thanks to their mobility and flexibility, coolers are an indispensable companion for anyone who doesn’t want to miss out on chilled supplies while on the go.

Coolers come in several variants that differ in function, energy supply, and purpose. The simplest form is the passive cooler, which works without electricity and is operated with cooling packs or ice – ideal for short trips and spontaneous picnics. It is light, inexpensive, and especially low-maintenance.

For longer trips or use in the car, electric coolers are popular. These are powered via the cigarette lighter or socket and reliably keep drinks and food at temperature. A distinction is made between thermoelectric coolers, which can actively cool and sometimes also heat, and compressor coolers, which are particularly powerful and can even deep-freeze – ideal for camping trips or hot days.

Absorption coolers, which can be operated with electricity as well as gas, offer a middle ground. They are silent and therefore especially popular on campsites with power connections or when camping. So you’ll find the right cooler for every need – from simple to professional.

A good cooler is characterized by a combination of functionality, efficiency, and user-friendliness. A central feature is the insulation performance: high-quality models keep the contents cool for many hours – especially in warm outdoor temperatures. For electric models, the cooling performance in degrees below ambient temperature is crucial. Powerful coolers achieve a temperature difference of up to 30°C or more.

Power supply is just as important. Many electric coolers offer both 12V and 230V connections, making them flexible for use in the car or at home. For longer trips or camping holidays, multi-voltage capability and alternative energy sources (such as gas) are a great advantage.

A low weight, sturdy carrying handles, or wheels ensure high transport comfort. Anyone wanting to cool sensitive contents benefits from temperature control, eco mode, or even a digital display. Extras such as removable inserts, cable compartments, cup holders, or lids with locking systems make use even more convenient. If you pay attention to these features, you'll find a cooler that’s perfect for your needs.

When buying a cooler, the main considerations are its intended use and the desired cooling performance. If you only want to cool for a short time, such as on a picnic, a passive cooler with cooling packs is a good choice. For longer trips, camping holidays, or continuous use, you should go for an electric cooler – ideally with good insulation and strong cooling power of at least 20–30°C below ambient temperature.

Another criterion is the power supply: models with a 12V connection are suitable for the car, while an additional 230V connection allows use at home or on the campsite. Absorption coolers offer even more flexibility with gas operation.

The capacity should also match the intended use – small boxes are sufficient for day trips, larger versions are useful for families or travel. Build quality, weight, carrying comfort (e.g., with wheels), and practical details such as removable inserts, cable storage, or lid locking systems are also important. Anyone who considers these points is guaranteed to find the right cooler for their needs.
