The Apple Store has launched a new 240W USB-C charging cable. This charging cable uses a braided body and has USB2.0 data transmission capabilities. This data cable supports PD3.1 nominal 48V5A 240W power charging and supports USB2.0 data transmission. By pairing this data cable with the PD3.1 charger, you can quickly charge the connected device and experience the time saved by fast charging.
Charging Head Network has purchased Apple's 240W USB-C charging cable. This charging cable is all white with a braided body design and matches the color of Apple's original charger. Let’s dismantle Apple’s new 240W USB-C charging cable and take a look at the internal workmanship and materials of this cable.
The packaging box continues the white simple design style, with the Apple logo, the English name of the cable and the appearance picture printed on the front.
The back is printed with the multilingual name of the product, a simplified diagram of the thread end, CE certification logo, etc. It has the same sticker design as the iPhone packaging box.

The metal shell of the USB-C male connector has the product model A2794, place of origin (Vietnam) and serial number on one side.

The knitted jacket with thread body is very tight, the surface feels slightly hard, but the overall texture is as soft as lines.
Knitted outerwear still twists the fiber filaments into one strand first, and then arranges and knits them. In this way, the wires are not easy to tangle, have good protection and are not easy to fluff, extend the service life, and improve the user experience.
The diameter of the wire body reaches 4.58mm, which is still relatively thick. The actual measured length of Apple's data cable is about 2 meters, which is fully in line with the nominal length, neither too long nor too short, and the cutting technique is accurate.
Using ChargerLAB POWER-Z KM003C, it was measured that this Apple data cable has an E-Marker chip, the power transmission capacity is 50V5A, supports PD3.1 240W full power charging, and the data transmission capacity is USB 2.0.
Using ChargerLAB POWER-Z KM003C, it was measured that this Apple data cable has an E-Marker chip, the power transmission capacity is 50V5A, supports PD3.1 240W full power charging, and the data transmission capacity is USB 2.0.
As can be seen from the histogram, the difference between the 5/9/12/15/20/28/48V1A gears is around 0.1V, and the difference between the 5/9/12/15/20V3A gears is around 0.35V. The difference between the 20/28/48V5A gears is between 0.57-0.59V. The gear with the highest difference is 0.59V for 28V5A and 20V5A, and the gear with the lowest difference is 0.09V for 48V1A.
Since there are currently no devices on the market that support 240W fast charging, Apple MacBook Pro 140W fast charging requires special wires. Here we can only use this data cable with Apple's 96W charger to conduct a simple charging power test on the Apple MacBook Pro. The measured charging power is 19.92V 4.64A 92.45W, successfully enabling 100-watt PD fast charging.
The last step is to test the data transmission performance. Connect the Apple 240W USB-C charging cable to the laptop and the hard drive box respectively. The HyperJuice USB4 hard drive box and the TiPlus7100 solid state drive are used. You can see that the computer's desktop is successful at this time. The hard disk is read, indicating that the cable supports data transmission.
Use Disk Speed Test on the computer to test the data transmission speed. The measured writing speed is about 32.9MB/s and the reading speed is about 35.8MB/s, which complies with the USB2.0 data transmission standard.
Apple 240W USB-C data cable disassembly
After looking at the appearance and display of Apple's data cable, let's dismantle it and take a look at the internal materials and workmanship.
First, use a cutting machine to cut the plastic shell of the USB-C plug. The internal terminals are reinforced with stainless steel sleeves. There are dense spot welding spots corresponding to the cables and plugs, which are used to fix the cable tail harness sleeve and USB-C plug. .
Continue cutting to cut through the inner stainless steel sleeve, and solder the small board connection to the inner USB-C terminal.
The left side of the terminal is the positive wire, three wires are welded in parallel, the middle is the CC wire and USB2.0 data line, and the right side is the negative bare wire.
Two chip capacitors are also soldered on the terminal board.
Remove the steel sleeve on the back of the small board and solder the E-Marker chip on the back of the small board.
Remove the steel sleeve on the back of the small board and solder the E-Marker chip on the back of the small board.
Next, disassemble the USB-C plug at the other end and use a cutting machine to cut open the plastic shell to expose the stainless steel sleeve inside.
Continue to cut the stainless steel sleeve, and the layout of the terminal plate is the same.
Cut the stainless steel sleeve and solder the E-Marker chip to the terminal plate.
The E-Marker chip is also covered with hard glue.
Cut the data cable and observe the cross-section. The outermost braided cable is twisted and the cable is not loose even after cutting.
Close-up of the cross-section of the cable. There are six wire cores with insulation inside. Three of the red wire cores are positive power wire cores, and the internal wire cores are thicker. The blue thin wire is the CC wire core, the white and green wire is the USB2.0 wire core, and the peripheral bare wire core is the negative wire core.
Inside the braid is a white cable sheath.
Inside the outer skin is a wrapped screen.
Inside the shielding net is shielding aluminum foil.
Peel off the shielding aluminum foil, and there are power wire cores and data wire cores inside, and the inside is also filled with tensile wires. The wire core has a rotating winding structure, which can better relieve stress and make the cable softer.
An overview of the internal winding cores of the cable.
The cables are all disassembled and viewed in order, including the braided jacket, plastic sheath, metal shielding mesh, shielding aluminum foil, power core, data core, etc. Let’s start with a detailed introduction to the core design inside the cable.
The three positive power wire cores are tinned copper wires with no tensile wires inside.

Apple's newly launched 240W USB-C charging cable is USB2.0 specification, and the cable length is about 2 meters. Since it has a built-in E-Marker chip to mark the cable's capabilities, this charging cable supports PD3.1 fast charging. The transmission power is 240W. Although there is currently no device that can reach the maximum transmission power of this charging cable, judging from the fact that Apple has launched a 240W charging cable, high-power fast charging is already on the way and its popularity is just around the corner.
Charging Head Network learned through disassembly that the USB-C plug of this charging cable is made of plastic shell, and the internal USB-C terminal is fixed by laser spot welding steel sleeve to increase the mechanical strength. The small plate inside the terminal is welded with an E-Marker chip, which is used to mark the cable transmission capacity. The cable has built-in shielding net and aluminum foil to resist interference, and is filled with tensile wire to increase the overall strength of the cable. A woven outer shell is also used to further enhance longevity. The overall workmanship is solid and the quality is reliable.
