What are the four wires inside a Type-C data cable used for?

1. The four colored wires inside a Type-C data cable each serve different functions. The red wire usually represents the positive power supply, the white wire represents the negative voltage data line, the green wire is the positive voltage data line, and the black wire serves as the ground wire (GND).

2. In the Type-C interface, the red wire is responsible for the positive power supply, and the black wire is responsible for the negative power supply. The green and white wires are used for the positive and negative data transmission, respectively.

3. Although the standard wire colors are red, white, green, and black, different manufacturers may use different wire color configurations. When using them, it is recommended to use a multimeter to correctly identify the cable colors and solder them according to the standard Type-C interface wire colors.

4. The green wire is sometimes used to indicate support for fast charging (such as Qualcomm QC), while the blue wire may represent USB 0. The meaning of different colored interfaces is not always clear; for example, purple may represent Huawei fast charging, while orange is often used in industrial equipment to indicate high-current transmission.

5. The color of the wires, besides providing a convenient way to distinguish between them, does not affect their material or performance. Ensure that the positive and negative poles are correctly matched during connection to avoid damaging the device.

6. Different colored charging cables may represent different charging technologies or protocols. For example, some manufacturers may choose specific colors to differentiate their fast charging technology. However, color is not the only identifier; product descriptions and technical specifications should be consulted when purchasing and using the cables.
