When used to charge the MEIZU 20 Pro, the measured wireless charging power is about 50.8W.

Teardown

Next, let's take it apart to see its internal components and structure.

Peeling off the protective pad on the support platform reveals hidden screws.

After removing the screws and taking off the cover, you will find the screws and indicator lights inside.

By removing the screws from the bottom and the support platform, you can open the wireless charging panel and take out the internal module.

The interior of the shell features partition plates on both sides and the back, designed to seal the side grilles and increase the airflow volume of the ventilation outlets, thereby enhancing the cooling efficiency.

The integrated black plastic stand is used to support and secure the PCBA module and wireless charging coil.

The USB-C interface area is equipped with a thermal copper sheet.

The front end of the stand is equipped with a wireless charging coil and an LED light panel, which is connected to the motherboard via red and black wires.

A heat dissipation fan outlet is located between the coil and the light panel.

A heat dissipation fan outlet is located between the coil and the light panel.

The wireless charging motherboard and the heat dissipation fan are securely fixed at the bottom.

The USB-C socket is fixed using a small board and screws.

The fan is also secured with screws.

Remove the screws to take out the fan.

The fan's wiring is connected to the motherboard via a plug-and-play connector.

The USB-C socket is connected to the PCBA module via a ribbon cable.

The front of the PCBA module features components such as the MCU, wireless charging power MOSFETs, wireless charging coil-switching MOSFETs, a synchronous buck converter, and solid capacitors.

The back of the PCBA module contains the wireless charging master control chip, resonant capacitors, and other components.

The USB-C socket is reinforced with a steel sheath and spot welding.

The filtering capacitor has a specification of 35V 47μF.

The wireless charging master control chip is from CPS, model CPS8200. It is a highly integrated wireless charging transmitter chip, featuring a 32-bit processor, with an embedded 64+2KB MTP, 32KB ROM, and 2KB SRAM. The MTP supports read/write protection and allows programming via CC and DPDN. It includes two I2C interfaces and two UART interfaces. The chip also integrates a switch-mode buck converter, linear voltage regulator, DC-DC controller, full-bridge driver, communication module, and multi-channel 12-bit ADC.

The CPS8200 supports fast charging protocols such as QC2.0/QC3.0/PD3.1/SCP/AFC. It integrates three pairs of half-bridge drivers, supporting both boost and buck conversion. It also supports fixed-frequency voltage regulation charging, and with the appropriate MOSFETs, it can form a complete Qi2 wireless charger product. The chip supports a 24V input voltage, with the power stage supporting up to 45V input voltage. It also features over-voltage, over-current, and over-temperature protection functions.
