Essentials Reverse Charging with an OTG Cable On-The-Go (OTG) is a USB transmitting technology that allows a device 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 device to charge other devices using an OTG cable. 1 Connect your device with the device to be charged using an OTG cable. 2 When the Use USB to dialog box is displayed on your device, touch Reverse charge. If another option has been set previously, the dialog box will not pop up. Swipe down from the status bar to open the notification panel, touch Settings, and then select Reverse charge. 3 Follow the onscreen instructions on the device to be charged to start charging. 30
