Smart power strip
Often monitors and air conditioners do not need running when no one is in the room. It is not the case, however, in reality. And a good solution is needed to cut off power when necessary.
This new product with a built-in sensor can detect whether there is anybody in the room, if not, it will automatically cutoff six of the eight sockets in 30 seconds to a half-hour. The other two sockets are normal ones to fit for chargers which need longer plugging.
Price: $90
