Introduction

ChargerLAB this time got a 2-in-1 USB-C to USB-C cable from Anker. Both USB-C output cables support a charging power of 140W, which can meet the 140W full-speed fast charging requirements of MacBook Pro. In addition, it also supports intelligent power distribution such as 112W+18W or 50W+50W. So you can charge two devices with this one cable. Next, we will take this cable apart and take a look at its design.

Product Appearance

ANKER and No.1 are printed on the front of the box.

The box contains the cable and some documents.

The USB-C input cable connector has an integrated shell with a matte surface and ANKER is embossed on the front.

The two USB-C output cable connectors on the other end have the same design.

The USB-C ports have a non-full PIN design.

The USB-C output cable has a plastic shell at the end to prevent bending.

The cable is woven with nylon, which is more wear-resistant and durable.

ANKER is printed on the case at the node where the cable is divided into two.

The length of the cable is about 132 cm (51.97 inches).

The diameter of the cable is 3.23 mm (0.13 inches).

The weight is about 55 g (1.94 oz).

The ChargerLAB POWER-Z KM003C shows that it has an E-marker chip and can support 50V5A and USB 2.0. 

Let's do some simple tests, starting with the voltage drop test. This test measured the difference between the input and output voltages. And this spec is an important factor in measuring the quality of the cable.

From the chart, we can see that the largest voltage drop difference is 0.8V for 20V5A, and the smallest difference is 0.14V for 28V1A.

Use one of the USB-C output cables with a 140W charger to charge an Anker power bank, the real-time charging power is about 130.83W.

Change to another USB-C output cable for testing, the charging power is about 131.55W. Both USB-C output cables can achieve 140W PD fast charging.

Teardown

Next, let's start to take it apart and take a look at the internal components.

Firstly, cut off the USB-C input connector, which is filled with hard plastic to protect the USB-C PCB.

Remove the inner plastic shell as well. The USB-C PCB is small and is only designed to connect the pins and wires.

Remove the node shell and the main components are all located on this small PCB.

One side of the PCB is equipped with a PD decoy chip, a protocol chip, and four MOSFETs.

The other side is equipped with a synchronous buck converter, an alloy buck inductor, and three MOSFETs.

The protocol chip of the two USB-C output ports is from Injoinic. It supports multiple USB ports, dual-port 18-140W fast charging, independent feedback control, and independent USB PD control, which is equivalent to integrating two IP2736 into one chip. It supports PD3.1, UFCS, PD3.0, PPS, and other protocols, and the compatibility is very good. Model is IP2738U.

Injoinic IP2738U has four independent NMOS drivers built in, which can be used for multiple ports output control, multiple VBUS MOSFETs for output port switching, and two power supply parallel controls. It also supports dual-way independent over-current, over-voltage and short-circuit protection to ensure safe use.

Here is the information about Injoinic IP2738U.

The programmable PD controller is from Injoinic and adopts DFN3*3-10 package. It supports bidirectional applications, Vconn power supply, programmable over-current protection, current capability definition and detection. It supports source, sink and DRP applications, and supports connection/detachment detection. It supports PD3.1 applications and uses I2C port for communication. The VBUS/CC1/CC2 pins have a voltage resistance of 28V. Model is IP2752.

Here is the information about Injoinic IP2752.

The four MOSFETs from VGSEMI are of the same model and adopts PDFN3333 package. 40V 6.4mΩ for each. Model is VS4620GEMC.

Here is the information about VGSEMI VS4620GEMC.

The buck chip marked with BAX is from MPS and adopts 2.5*3mm QFN-13 package. It has built-in MOSFET. It supports an input voltage of up to 32V, output voltage of up to 30V, and 6A maximum output current. It has a built-in 33mΩ/22mΩ synchronous buck MOSFET and supports adjustable current limit. Model is MP2491C. 

The alloy buck inductor is marked with 4R7.

The two MOSFETs next to the inductor also come from VGSEMI. Model is VS4620GEMC.

The other MOSFET that adopts PDFN3333 package is also from VGSEMI. Model is VSE014P04MS. -40V.

Here is the information about VGSEMI VSE014P04MS.

Next, let's cut off the cable. From outside to inside, there are braided layer, plastic layer, shielding net, shielding foil, wires, and tensile wire.

The red positive wire is made of tinned copper wire with tensile wires inside.

The negative wire core is exposed.

The green wire used for USB 2.0 data transmission adopts D+ cores and also has tensile wires inside.

The white wire used for USB 2.0 data transmission adopts D-wire cores and also has tensile wires inside.

The blue CC wire also has tensile wires inside.

These are the parts of the disassembled cable.

Disassemble the USB-C output connector, and the internal design is the same as the input connector.

The welding point between the wires and the small PCB is protected by glue.

Well, those are all components of Anker 140W 2-in-1 USB-C to USB-C Cable.

Summary of ChargerLAB

The Anker 140W 2-in-1 USB-C to USB-C Cable is a braided design and comes in black, which makes the product more resistant to dirt and durable, while also giving it a more classy look. It can provide 112W+18W or 65W+27W charging power for laptops and phones. When charging two laptops, it will provide 50W+50W charging power. The output power is intelligently distributed according to the devices. Both USB-C output cables support a charging power of 140W, which can meet the 140W full-speed fast charging requirements of MacBook Pro. Additionally, it can charge two devices simultaneously. The practicality is very good.

After taking it apart, we found it is designed based on the protocol chip IP2738U and PD decoy chip IP2752 from Injoinic. It also uses the step-down chip MP2491C from MPS and multiple MOSFETs from VGSEMI. The cable is equipped with a shielding net and shielding aluminum foil to prevent interference. It also has built-in tensile wires no matter in the cable or the wire cores. The overall workmanship is good.
