OPPO currently only has one, the OPPO Finder (X907), which supports wireless charging using a wireless charging kit.
Finder's wireless charging mechanism: the three contacts on the side of the phone are wireless charging connection points. When wireless charging is realized, the phone needs to wear a charging protective case, and the receiving circuit in the charging protective case is connected with the three contacts of the phone.
The charging base is connected to the power adapter through USB, and there is a transmitting circuit in the charging base; Wireless charging can be achieved by placing the phone with the charging case directly on the charging base.

OPPO Finder (X907) Wireless charging of mobile phones works:
Using the physics principle of \"resonance\" - two objects that vibrate at the same frequency can transmit energy efficiently.
1. The electrical energy in the transmission line is passed into the antenna made of copper.
2. The antenna vibrates at a wavelength of 10 MHZ, producing electromagnetic waves.
3. The energy from the antenna travels up to 2 meters (6.5 feet) away.
4. The laptop computer, which also vibrates at 10 megahertz, receives the current and the energy is charged into the device.
5. Energy that is not converted to a laptop is not reabsorbed by the antenna. People and other objects that cannot generate a 10 MHZ resonance will not interfere with it.
