The Save A Watt Edge is an easy to use timer that is equipped with a tethered motion sensor to detect when there is activity in the room. Whatever device is plugged into the timer will cut off vampire and/or standard power when not in use in accordance with the time increment of your choice, as displayed on the side of the timer. Use the Save A Watt Edge when plugging in power strips so that almost an entire room may be shut down during the long periods of time that you are not inside them. 1320W. 10Amp. Grey.
