This four port charger makes it easy to be eco-friendly. Now you can charge your USB connected devices without turning on a computer and without draining unneeded electricity or short circuiting your device once it has fully charged. Plug the device in the wall, set the charging time for 2, 4, 6, or 8 hours and once the time is up, the charger consumes zero watts. (Source: Vogduo)
