If memory serves right, this was my first attempt at designing something made 2 or 3 years ago - an intelligent charger.
 
By adding an indicator to the plug portion of the charger, the user can see whether the device has been fully charged or not from some distance. By adding a blinking functionality, the user can also be notified about missed calls, messages and other important notifications.
