For USB-C cable, the same appearance design of the two cables does not indicate the data transmission capacity and power supply capacity of the cable.Like the two contrasts in this articleAppleThe data lines are the same. Although they use the same appearance design and the same braided body, the two lines, one supporting 240W fast charging, and the other only supporting 60W fast charging, have a huge difference in charging performance.
The charging head network will use a disassembly article to disassemble and compare the two data lines to see what are the internal differences between the data lines that support 240W power transmission and 60W power transmission.
Product appearance
appearance
The appearance design of the two data cables is the same, and the knitting process of the connecting body is also the sameAppleThe 240W fast charging data cable is longer and thicker.
Thread head overview
Both wire ends of the two types of wire rods are high bright white shell, with arc transition on both sides, and there is no net tail design at the junction of the wire body and the wire end.
Close up of PIN pin
The number and layout of the internal pins of the USB-C male connector of the two lines are the same.
length
MeasuredAppleThe 240W fast charging data cable is about 2m long,AppleThe 60W fast charging data cable is about 1m long.
Diameter of wire body
MeasuredAppleThe diameter of the 240W fast charging data line body is 4.58mm, and the diameter of the Apple 60W fast charging data line body is 3.25mm. From the measurement data, there is a big gap.
weight
The measured weight of Apple 240W fast charging data line is about 78g, and the weight of Apple 60W fast charging data line is about 19g.
internal structure
Terminal layout
The terminals of the two lines are reinforced with stainless steel shells, laser spot welded to the metal shell of the USB-C plug, and the tail is fastened to fix the cable.
Small board layout
The USB-C plugs of the two data lines are welded to the small board, and the wires are welded to the small board.The connecting board of 240W data line is welded with E-Marker chip, and the connecting board of 60W data line is equipped with bonding pad.
Pin
Both data cables use gold plated pins.
Body section
In terms of wire body section, the two data lines are designed with six cables, three of which are used for positive power transmission, but the 240W data line needs to pass 5A current, and the withstand voltage level is improved. Three thickened positive power lines are used, and the corresponding USB data line sheath is also thickened to enhance insulation.The core of the 60W data cable is not thickened, and the cable center is also filled with anti stay wire.
Workmanship and materials
E-Marker chip
The Apple 240W data cable uses Infineon's E-Marker chip to mark the power transmission capacity of the cable, and adopts Infineon CYPD2803A1-09FNXI.The chip supports USB PD3.1 and USB Type-C 2.1 specifications, and supports lightning 4, USB4 and EPR cable applications.
Wire core
Positive power core
The same design of three positive cores is used inside the two data lines, but the core inside the 240W data line is significantly thicker than that of the 60W data line.
Negative power core
The negative power core is designed as a bare core, the 240W data line uses four thickened bare cores, and the 60W data line uses six thin cores.
Data core
CC line
The CC cable inside the data cable adopts light blue translucent sheath, the CC cable of 240W data cable adopts sheet winding structure design, and the CC cable of 60W data cable adopts conventional multi strand design.
D+core
The D+core of the USB2.0 data cable adopts the same design, with green translucent sheath and multi strand core design.
D-core
D-core of USB2.0 data cable, two data cables adopt the same design, white translucent sheath, multi strand core design.
Product performance
Power/data transmission capability
Using ChargeLAB POWER-Z KM003C, it is measured that Apple's 240W fast charging data cable is equipped with an E-Marker chip, and its power transmission capacity is 50V5A. It supports PD3.1 240W full power charging, and its data transmission capacity is USB 2.0.It is measured that Apple's 60W fast charging data line does not have an E-Marker chip, its power transmission capacity is 20V3A, and its data transmission capacity is USB 2.0.
Summary of charging head network
Finally, a comparison table of Apple's two data lines is attached to facilitate you to compare the differences between the two products.
Apple's 240W and 60W data cables are both USB2.0. The length of the 240W cable is 2 meters, while the length of the 60W cable is only 1 meter. The corresponding weight is heavier.Both types of data cables adopt braided wire body, which changes the phenomenon that the traditional cable sheath is easy to damage you and is more durable.The terminal adopts white plastic shell, continuing the previous design style.
In the 240W data line, Infineon E-Marker chip is used to mark the transmission power of the cable. The transmission current reaches 5A. The supporting current of the 60W data line is 3A, and the length of the 240W cable is 2 meters. Therefore, the thickened core is used to meet the demand for long-distance large current transmission.Both types of cables are designed for specific purposes. The 240W cable is a cable for the future, while for Apple mobile phone charging, the 60W cable can be used.
