what is reverse charging

Reverse charging is a feature that allows a device to charge other devices that support wireless charging. It is also known as reverse wireless charging or wireless powershare. The device with reverse charging capability has a coil that carries AC current, which generates a magnetic field around it. The technology is based on Qi charging, which is the same physics involved in wireless charging. Reverse charging is usually equipped in smartphones with big batteries (over 5000 mAh) that support OTG function. These smartphones are equivalent to power banks and can charge compatible devices like cellphones, TWS earbuds charging box, Bluetooth speaker, smartwatch, and more. To use reverse charging, the device to be charged must support wireless charging, and non-Huawei devices must support the QI wireless charging protocol. The device being charged must be powered on and placed on the center of the back of the phone, and no metal objects should be placed between the two devices. Reverse wireless charging is less powerful than wired charging, and it may take longer to charge large-capacity devices. It is best suited for charging wireless accessories and for emergency situations. To enable reverse charging on Android devices, go to the battery settings and turn on the reverse wireless charging option.
