Over-Charging Protection [Auto-Disconnect] This cable is smart and intelligent as it senses the charging level of the connected device and disconnects the device form charging when the device gets completely charged. The IC chip in the connector of the cord stops the power supply to the device 20-25 mins after the device gets completely charged, thus protecting the device form problems arising due to over-charge such as heating, decreased battery life and efficiency. The LED indicator informs about charging status (i.e. different Lights up mode if the device is charging and completely charged)
