People usually charge their cell phone or other electronic devices over the night, however, they have not consider the extra electricity consumed even the devices are fully charged... So this special power strip could probably be one of the best solutions!
The charger can detect whether the electronic device is fully-charged up or not. If the device is hundred-percent charged, it blocks the electricity from flowing into the charger, the indicated led turns from red to green and the switch will automatically jump to off, so it prevents the batteries from overcharging.
