Thermoelectric coolers

A thermoelectric cooler works on 12V or the power grid. You can use it in the car, at the campsite, or on the go. It cools to up to 20°C under the outside temperature. Some models also have a keep-warm function. With a 20 to 40L capacity, you can take bottles, sandwiches, and snacks with you. This cooler makes a bit more noise, but is useful for days out or short vacations.
