Geektech found this technology very interesting, you must have seen your old washing machines with the timer knob or your ovens but this is what is very practical and a brilliant application of the age old technology. Here is a interesting design to save energy where the designer has used the timer knob on a electrical plugin board.
This can avoid ruining your gadgets by over charging them and using this interesting timer plug port. So for gadgets that need 2-3 hours of charging, the timer automatically turns off the power supply once the time is up. As the designers explains, “Turn it counter-clockwise to power sign to set for regular use and clockwise to set timer for gadgets that need only limited time of power.”
