This socket allows smartphones, tablets, cameras or MP3 players to be charged up at fixed locations anywhere in the house. There is no longer the need to search for USB charging stations, each with their own power adapters and electric cables. When the socket is exchanged, the location for a plug remains. The integrated, increased touch protection ensures higher safety during use. What is more, the socket is energy-saving. When nothing is being charged up, the electricity consumption is less than 0.1 watt.
