USB ports and 12 V sockets have been available in vehicles for a long time. The DXP can now be ordered with a 230 V socket on request. The connection delivers 3000 W nominal power and even 6000 W power for short periods. This is perfectly adequate for operating devices such as drills, electric hedge trimmers or floodlights. The DXP thus becomes a power source for work wherever there is no mains electricity available.

At the Parcel+PostExpo trade fair and currently at transport.ch in Bern, the socket is used to power the coffee machine in the front cabriobox for demonstration purposes. The vehicle is not connected to the mains electricity supply. A built-in inverter converts the direct current for the socket into alternating current.

The solar cell on the vehicle roof is also clearly visible. The solar module feeds the vehicle battery. Once this is fully charged, the electricity is fed into the grid. When the vehicle is at home and connected to the grid, a switch can be used to determine whether it is charged from the grid or only from the solar roof.
