Thanks to the 12 V mains connection, the Weber Home cool box can be easily charged in the car. In order to achieve the ideal temperature, it is advisable to put already chilled products in the box, otherwise the cooling process takes a lot longer. Already warmed up food can be kept warm with the heating function of the box over several hours. However, it is not possible to warm up cold dishes. With the 220 V adapter, the cool box can also be easily connected to a conventional socket. This adapter is not included.
