Preface
Belkin has introduced a Belkin Connect USB-C to dual-port USB-C adapter with two USB-C ports that allows you to connect chargers up to 100W to charge laptops and phones, and add a USB-C port for data transfer.
The 16cm length of this converter is very suitable for connecting to a Macbook notebook, and it is also suitable for the iPhone 15 series phones launched this year, which can be used for high-speed data transfer and music listening while charging a laptop or mobile phone. The following charging head network will bring the dismantling of Belkin's data + charging converter, and take a look at the internal materials and workmanship.
Belkin USB-C Data + Charging Converter unboxing
The box is in a classic white and green color scheme, and the Belkin brand, product name, appearance and selling point are printed on the front.
The back is printed with a product introduction diagram and related descriptions, as well as CE, FCC and other certification information.
The package contains a Belkin USB-C Data + Charging Adapter and instruction manual.
As a product on Apple's official store, the Belkin USB-C Data + Charging Converter is designed with a white body, USB-C cable head and light gray cable body, with a strong Apple style.
The USB-C cable head adopts a white glossy shell with semi-circular curved surfaces on both sides.
The thread body is bent resistant.
The output shell of the fuselage is printed with product-related parameter information.

The products have passed CE, KC, UKCA, CP, NOM, NYCE certification, and are made in Vietnam.
The fuselage is made of PC fireproof material white shell, indicating a high-gloss glossy finish, and the two sides are also semi-circular arc design.
The top side of the fuselage is printed with the Belkin brand.
The corresponding input interface on the back is printed with the corresponding prompt logo.
The corresponding two USB-C ports are printed with 100W PD input and data transmission logos respectively.
There are two USB-C ports on the input, of which the USB-C port on the left is the charging port, which supports 100W PD fast charging input. The USB-C port on the right is a data transmission interface that supports USB 3.2 Gen2 (10Gbps) transmission specifications.
The measured end-to-end length of the Belkin USB-C data + charging converter is about 16cm.
The length of the fuselage is 50.08mm.
The width is 59.12mm.
The thickness is 13.77mm.
The size of the product in the hand is intuitively felt.
In addition, the net weight of the measured Derkin USB-C data + charging converter is about 42g.
The actual application scenario of Belkin's USB-C data + charging converter is shown in the figure, the USB-C cable is connected to the new iPhone 15, and the other two ports are connected to the charger and the hard disk enclosure equipped with the SSD, which realizes the charging and data transfer operation of the mobile phone at the same time.
Since the new iPhone 15 series USB-C port is limited to 4.5W, some USB-C data transfer devices (such as SSDs) require more power. Another highlight of the product is that it can power both the phone and the SSD enclosure at the same time, so that the new Apple iPhone 15 series can record 4K@60Hz video directly to the USB-C SSD directly through the camera app, which is convenient and easy to use.
As you can also see from the enclosure display, the enclosure delivers 216MB/s (about 1.69Gbps) write speeds when recording video directly to a USB-C SSD, which is less than one-fifth of the USB-C data port performance. It can be seen that the performance of Belkin's converter in terms of charging and data transfer can fully meet the daily use needs of Apple's new iPhone 15 series.
Belkin USB-C Data + Charging Converter Teardown
After reading the unboxing and display of Belkin's converter, let's disassemble it and take a look at the workmanship and materials inside.
Start by prying open the case along the seam of the case and remove the side panels.
Cut the case along the side and remove the internal PCBA module.
The PCBA module is fixed inside the housing by gluing.
The front and back sides of the PCBA module are equipped with metal shields.
Remove the shielding covers on both sides of the PCBA module and continue to disassemble.
The front side of the PCBA module is welded with VBUS switch tube, synchronous buck-boost converter, filter capacitor, buck-boost inductor, and right-side soldered hub chip, toggle switch chip and USB PD controller. Solder the output leads above and two USB-C sockets underneath.
A VBUS switch tube, filter capacitor and other components are welded on the back of the PCBA module. The two USB-C receptacles are fixed by soldering through the sinking plate to reduce the overall thickness.
The USB-C cable adopts a metal wire card and is soldered and fixed. The data lines are equipped with ESD protection diodes for electrostatic protection.
The back side is welded with positive and negative power supply wires.
The USB hub chip is from Weifeng Electronics, model VL822-Q5, which has obtained USB 3.2 Gen2 USB-IF certification, TID number 1932. The VL822-Q5 has two downstream interfaces and supports USB3.1 Gen 2 10Gbps transfer rate for USB-C interface expansion.

Summary of the dismantling of the charging head network
The Belkin adapter has two USB-C ports, and by connecting the adapter to a laptop or phone, you can expand a single USB-C port into two, so you can charge and transfer output at the same time. The measured converter is 16cm long, which is ideal for connecting laptops or mobile phones, and supports 100W charging power and 10Gbps data transmission.
Through the dismantling of the charging head network, it was learned that Belkin's converter uses Weifeng electronic solutions, using VL822-Q5 hub chips with VL162 transfer switches and VL107 interface controllers. The VL107 has a Secure FW Update Console, which allows Apple to update the firmware of this converter from Apple's program.
The converter also uses an MPS MP28167 synchronous buck-boost converter to power the data interface, and a MP28200 and MP28167 to power the internal chip. A Texas Instruments TPS63036 synchronous buck-boost converter is also used. The front and back sides of the internal PCBA module are covered with metal shields. The interface is equipped with ESD protection diodes for electrostatic protection, and the internal workmanship and materials are very good.
