First, Huawei Mate RS Porsche wireless charger out of the box
The main body adopts a one-piece metal fuselage. The surface is frosted and anodized, and the hand feels delicate. At the same time, it ensures good heat dissipation performance.
Second, Huawei Mate RS Porsche version of the wireless charger dismantling.
The coil heats the shell through the aluminum plate.
The circuit board component surface also has silicone-assisted thermal conductivity, which reduces the temperature rise of fast wireless charging.
Aluminum alloy bottom shell process is fine.
There is thermal grease in the middle of the magnetic sheet and heat sink.
Indicator light guide.
On the front side of the board, the heat-generating components have silicone heat conduction.
The pad of the thermistor is fixed and the solder joint of the wireless charging coil looks very comfortable.
Four NPO capacitors.

All dismantling at a glance.
Third, charge head net dismantling summary
This product uses the United States IDT IDTP9237 wireless charging scheme, providing protection for 10W fast wireless charging. Many internal heat dissipation methods such as silica gel and aluminum plate can effectively prevent the influence of temperature rise on wireless charging power. Large volume capacitors, which are rarely used in the industry, have also been adopted to cope with high-current interference and full of sincerity. Overall, this Huawei Mate RS Porsche wireless charger has a well-designed interior, exquisite workmanship, solid materials, and a reputation for Porsche design.
