Within 15 minutes the whole installation can be set up without any supplementary tools. Electricity comes from the car’s battery, and powers equipment such as the pump, the water boiler and the optional add-ons such as the fridge, and iPod and computer chargers. The battery though will always leave a little energy (11 volts) to start the car’s engine for the next ride. The SwissRoomBox is currently only shipped to Europe. Prices start at CHF 8,630.
