What is Reverse Charging and How Does it Work?
Reverse charging is a technology that allows a device, typically a smartphone, to act as a power source and charge other devices. This is achieved through a process called “reverse wireless charging” or “two-way wireless charging.” When a device is enabled with reverse charging, it can transfer its own battery power to another device, such as a smartwatch, headphones, or even another phone, using a wireless charging coil.
The process of reverse charging involves the device’s charging coil being used as a transmitter, rather than a receiver. When a device is placed on top of the enabled device, the coil detects the presence of the other device and begins to transmit power. The power is then received by the other device’s charging coil and used to charge its battery. Reverse charging is a convenient feature that eliminates the need for multiple charging cables and allows users to charge their devices on the go.
What are the Benefits of Reverse Charging?
One of the primary benefits of reverse charging is its convenience. With reverse charging, users can charge their devices without having to carry multiple charging cables or find a power outlet.
