Last week we published a review of Sony’s Wireless Charger, and since the product cost a whopping 798 yuan, many readers asked us to do a teardown. So of course we went ahead and did just that.
Sony uses simply adhesive to piece the two sides of the body together. Luckily, I have long nails, so just a nip and pull from the bottom managed to do the trick.
Despite using just glue, the adhesive is strong.
The cover material is a TPU polyurethane material, crafted in February of 2018.
A large piece of magnet can be seen cover the sides.
The USB-C port is surrounded by four screws.
Right here you see the screws hold the coils in place.
This piece was manufactured in February too.
The coil has a transparent area for LED lights.
Taking off the coil cover, you’ll see the double coil structure, respectively responsible for propping up the charger horizontally. The lower right you can see the flexible cable connection 4 LED, two positions of the red / white indicator light, Used to determine the charging status.
There is a fan for heat dissipation.
You can see that the fan is powered by a 12V0.1A silent motor.
Check out the details here with the PCB, cooling fan, and coils all installed on the motherboard.
ChargerLab found that the Sony charger uses the IDT IDTP9242 15W wireless charging transmitter chip from the US, which supports object detection (FOD) input voltage range 4.25V-21V, in line with WPC1.2 standard, built-in over-current temperature protection, support programming LED mode.
The joints have been sauntered using high heat.
Three big, one small NPO.
Using our portable mobile power USB-C output port as the power supply side, our POWER-Z monitor Sony wireless charger communication, successful connected at PD 5V.
Our ChaegerLab POWER-Z host computer checked the capture situation, Sony WCH20 indeed supports PD power supply.
After the dismantling of the Sony Wireless Charging Stand, we liked the anti-slip TPU surface, and the four LED lights that are responsible for the horizontal/vertical display of the charging mode light, which is then emitted from the magnetic suction plate through the light guiding structure. The IDT IDTP9242 wireless charging transmitter solution and dual coil is also a solid solution.
In order to deal with the heat generated, the entire cavity adopts a four-sided vented ventilation design. The built-in Delta fan actively cools the air. It draws cold air from the bottom through the PCB and blows it to the magnetic insulation board. The hot air is discharged through the guide grille and is cooled. The hot air does not mix to form the air duct for rapid heat dissipation. In addition, the PD input is supported by the Cypress CYPD-2122 USB-C chip, which can be successfully handshaked by using the ChargerLab POWER-Z host computer.
This is exquisite workmanship that stands up to scrutiny, and the airways are forcibly forced to a high level. This is worth the higher than usual price.
