preface
With the update of the USB PD3.1 standard, the upper limit of PD fast charging has also been increased to 240W, and many brands on the market have also launched data cables that can support 240W fast charging. However, there is currently no matching 240W fast charging charger and equipment, which also makes these cables unable to give full play to their advantages.
Recently, the charging head network got a 2-in-1 USB-C fast charging data cable from Anker, and its two USB-C output cables can support 140W fast charging, which can meet the current Apple MacBook Pro 140W full-speed fast charging needs, and at the same time easy to use. In addition, it also supports intelligent allocation strategies such as 112W+18W or 50W+50W, which is equivalent to "adding" a fast charging port for high-power chargers, which is more practical. The following charging head network will disassemble this cable and see the specific design of the product.
Anker 2-in-1 USB-C cable unboxing
The front of the box is printed with the ANKER brand as well as No.1.
The package contains a data cable and an instruction manual.
The USB-C input cable terminal housing is integrated with the network tail, the surface of the housing is matte, and the ANKER brand is printed on the front.
The two USB-C output cable terminals at the other end are designed in the same style.
USB-C male internal non-full PIN design.
The end is provided with a mesh tail to resist bending.
The thread body jacket is made of nylon material, which is more classy, and at the same time more wear-resistant and durable.
There is a runway-type shell at the second node of the wire, and the shell is designed with the ANKER brand.
The total length of Anker's data cable is about 132cm.
The diameter of the wire body is 3.23mm.
In addition, the total weight of the cable was measured to be about 55g.

In terms of pressure drop test, the test data results of the 13 gears of the wire rod are shown in the above table.
Drawing the histogram, it can be clearly seen that the gear with the largest voltage drop difference is 0.8V at 20V5A, and the gear with the lowest difference is 0.14V at 28V1A.
Finally, use this data cable with a 140W charger to charge the Anker power bank, and use one of the USB-C cables to connect the power bank, and the measured power is about 130.83W.
Changing to another USB-C cable for testing, the charging power was also measured to be about 131.55W. As a 2-in-1 data cable, both USB-C cables can achieve 140W PD fast charging.
Anker 2-in-1 USB-C cable teardown
After reading the appearance and test of the Anker 2-in-1 USB-C data cable, let's disassemble it and take a look at the design and workmanship of the cable.
Disassemble the USB-C input cable terminal housing and fill it with hard plastic to protect the USB-C terminal board.
The inner plastic case is also removed, and the USB-C terminal board is small and designed only to connect the PIN pins and cores.
The shell at the node is disassembled, and the core components of the cable are located on the small board.
One side of the small board is equipped with a PD decoy chip, a protocol chip and four MOS tubes.
On the other side, there is a synchronous buck converter, an alloy buck inductor, and three MOS transistors.
The two USB-C output protocol chips use Yingjixin IP2738U, which is a protocol chip that supports multiple USB interfaces, supports dual-port 18-140W fast charging applications, has independent feedback control, and has independent USB PD control, which is equivalent to two IP2736 integrated into one chip, and the fast charging specifications are the same as IP2736. It supports USB PD3.1 28V EPR gear, UFCS fusion fast charging, and PD3.0/PPS and other rich and comprehensive fast charging protocols, and the compatibility is very good.
Yingjixin IP2738U built-in four independent NMOS drivers, which can be used for output control of multiple interfaces, control multiple VBUS switches for output port switching and parallel control of two power supplies, and support dual independent over-current, over-voltage and short-circuit protection to ensure safe use.

Summary of the dismantling of the charging head network
The Anker 2-in-1 USB-C fast charging cable is designed with a braided cable and adopts a classic black color scheme, which makes the product more resistant to dirt and durability, and at the same time, the overall appearance is more classy. The data cable can provide 112W+18W or 65W+27W fast charging for notebooks and mobile phones, and 50W+50W fast charging for two notebooks, and the output strategy is intelligently allocated according to the size of the device.
Nowadays, 240W fast charging data cables are single-function design, and Anker's data cable is not only capable of these cables for Apple MacBook Pro 140W fast charging needs, but also does what these cables can't do, fast charging for up to two devices, which can be said to be very practical.
Through the dismantling of the charging head network, it was learned that this 2-in-1 USB-C fast charging data cable is designed based on the Yingjixin protocol chip IP2738U and PD decoy chip IP2752 core scheme. At the same time, MPS MP2491C step-down chip and multiple Weizhao MOS transistors are used. The wire body is equipped with a shielding net and shielding aluminum foil for anti-interference, and at the same time, there is a built-in tensile wire, and an anti-tensile wire is also provided in the core, and the overall workmanship is good.
It is worth mentioning that Yingjixin has also launched a 1C extension 2C cable-F evaluation board based on its own DC-DC step-down chip IP6551, protocol chip IP2738U, and PD decoy chip IP2752, which can meet the design needs of customers for two-in-one high-power fast charging cables.
