So long as a cord is plugged into the wall, it will continue to draw electricity. The PowerCutter Charger concept is the solution to lessening unnecessary electrical wastage with a smart mechanism integrated into one end. This innovative proposal won Soheyl Ghiami and fellow designers a 2012 Red Dot Award.
In the head of the adapter is a built-in switch and a detector that determines whether or not any power is being consumed at the end of the cable. When it isn't in use, the device then ejects its tip slightly to reveal a red band, indicating its inactive state. The internal shift and the separation of the connector within the casing of the PowerCutter Charger breaks the circuit so that electrical flow ceases.
