Reverse Charge with an OTG Cable

On-The-Go (OTG) is a USB transmission technology that allows a phone to directly access files on a USB flash drive or digital camera, or connect to an external device such as a keyboard or mouse, with the help of an OTG cable.

You can use your phone to charge other devices using an OTG cable.

  1. Connect your phone with the device to be charged using an OTG cable.

  2. Swipe down from the upper left edge of the screen to display the notification center, touch Touch for more options, and select Reverse charge.

  3. Follow the onscreen instructions on the device to be charged to start charging.
