USB reverse charging refers to turning a USB port on a smartphone or other portable electronic device into a power source in order to charge other devices. The solution includes installing a reverse charging chip in the USB port and using a battery with a reverse charging function.
This method can be used to charge low-battery devices without other power sources, such as smart watches, wireless headphones and smart bands. However, it is important to note that reverse charging can have a negative impact on your smartphone's battery life.
USB reverse charging is the use of a phone or tablet to charge other devices or phones. To use USB reverse charging, the device needs to support OTG functionality and reverse charging. If your device does not support it, you will need to use a specialized reverse charging adapter. Because the reverse charging process may consume a lot of phone power, it is recommended to use when necessary, rather than frequent use. When used at the same time, care should be taken to prevent excessive power consumption and lead to power failure of the equipment.
Specific solutions are as follows:

2. Find USB Debug in Developer Options and click Open.
3. Click OK.
