Since Xiaomi launched the Mi MIX 2S, this has become its new flagship, full-screen equipped with a Snapdragon 845 processor. Among all its features, one of the most popular is the new wireless charging function, being the first Xiaomi mobile equipped with this kind of compatibility. Reason why the company’s choice was presented, during the launch event of the phone, launching at the same time the Xiaomi Wireless Charger, a 100% Xiaomi wireless charger that was matched with the Mi MIX 2S. It is compatible with ordinary 5W and with 7.5W fast charge, in addition to coming with protection against overcurrent, overheating and detection of foreign objects.
Although it is a complement to the new Xiaomi flagship, it can also be used with other competing brand terminals that support wireless charging. Previously we made a summary of its features thanks to an unboxing, this time we will share a disassembly of the Xiaomi Wireless Charger to know the wonders that we have inside this device.

2. Xiaomi Wireless Charger: Small review of its characteristics
The entire surface of the Xiaomi Wireless Charger is white without details; There is no text or logo. For its manufacture PC was used as a base material of the shell, then the surface was covered with a thick layer of silica by a secondary injection molding process. In the hand feels soft and a certain degree of anti-slip effect is added, so the phone will not fall off.
On the back, the bottom of the charger has a non-slip rubber pad to prevent the charger from slipping when used.
The loading plate has a radius of 47 mm and a thickness of 12.44 mm. It uses a type C USB input interface and supports 5V2A / 9V2A inputs.
Finally, a green indicator light is hidden on the side edge of the wireless charger and shows the current charge status. The green light is always on under normal load but will flash when the protection mode is activated.
3. Xiaomi Wireless Charger: Disarming the charger
The Xiaomi wireless charger has top and bottom screws in the base. To see them it is necessary to gently remove the rubber mat.
Now, unscrew the screws.
Once the bottom cover is removed, you will see details on it from which a convenient reinforcement design is used.
All parts are mounted just below the bottom cover. A piece of black metal adhered to the upper cover and to the PCB is what acts as a heat conducting block. This is responsible for extending the heat and distribute it evenly to avoid overheating. Above we find the circuit board (PCB), which is the core of the Xiaomi Wireless Charger.
To remove the piece of metal next to the PCB it is also necessary to unscrew all the screws. Specifically, the metal heat sink that is fixed by clips with bolting points that attach it to the plastic cover.
On the other hand, the interior is translucent and this is achieved by using a black light-proof adhesive sheet.
The type C USB port is soldered at four different points on the PCB.
Finally, the metal heat sink is separated from the upper cover module.
The load coil is located in the middle, just above the PCB and welded in two places.
There is also a temperature sensing sensor that, in case of perceiving high values, allows the Xiaomi wireless charger to enter the protection mode.
Next, a knife was used to scrape the metal block. It was discovered that the net of the loading head was made of an anodized aluminum material.
The temperature probe is placed in the middle of the coil.
In the coils, a high degree of care was taken in the welds, as well as with the LEDs of the chip, while the rest of the wiring is stuck to avoid vibrations.
Looking more closely we have the overvoltage protection component Tvs and the common mode inductance to avoid interference.
Transmission section of the coil, winbond 25X40CL + vgsemi VS3622A.
Wireless charging section, US IDT IDTP9237.
Four npo capacitors, high power guarantee.
4. Xiaomi Wireless Charger: Dismantling summary
The company behind the Xiaomi Wireless Charger is Kunshan United Electronics Co., Ltd. (owned by Lixun Precision), and shares manufacturing methods with the creators of the Apple Wireless Charger. Also, using the IDT IDTP9237 wireless charging scheme in the United States, it is exactly the same as the ZMI wireless charger. The internal design is reasonable to withstand the same wireless fast charge of 7.5W at such a low sale price. An accessory that is definitely worth recommending.
