When you see the USB port of your laptop or desktop, you will find that there are many colors of the USB port; These colors are not just for good looks, in fact, different colors represent different performance, so what do these USB ports with colors mean, the following is a detailed introduction to the meaning of different colors. --Wu Zhonghan.
CommonColor:
Note:
White is USB10. Black is USB20, the transfer speed is about 60mb s, which is the most traditional speed and the slowest charging speed;
The dark blue is USB30, the transfer speed is about 640 mb s, which is very fast compared to the previous generation;
The light blue color is USB31. The transfer speed is around 1280 MBS.
White, black, dark blue, light blue, mainly related to the transmission speed.
Purple, green, yellow, red, orange, mainly related to charging.
Red USB31 interface, the transfer speed is 1280 MB s, and it supports charging when the computer is turned off like yellow and orange.
Purple is Huawei's fast charging interface, which can reach a speed of 1280MB s; Green is the Qualcomm fast charging interface, which is not a very common interface.
Actually, USB port color is one of the ways to identify the USB type, but it is not the standard and recommended method to identify the USB type. Typical manufacturers will follow a similar color pattern. usb3.The 0 specification does not specify what color must be used for the interface, and the use of blue or other colors is just for the sake of more intuitive and 20 interface to distinguish and highlight product features (or selling points). Therefore, it is not possible to distinguish USB3 simply by the blue interface0。Two more reliable ways to identify USB30 pins are the most accurate USB30 has a higher transfer rate at 2On the basis of 0, two sets of data lines and a ground pin are added, which are divided into two rows before and after, with a total of nine pins. usb3.0 has the "ss" logo, which represents:"superspeed"。
Distinguish the USB specifications directly by looking at the pins, and the four pins are USB20,Looking inside, there are two pins that are basically no different from usbgengen2,Because the interfaces of 3gen1 and 3gen2 are made of type-c,3.Type-C with 0 has 24 pins, and some merchants have 2There are only 16 of 0.
usb3.In version 1, a USB Type C interface was introduced to support insertion without distinction between the front and back, and 32. Later versions and Thunderbolt ports only support USB Type C interface;
White or black: represents the maximum current of 2A or 3A;
Purple: It means that it supports fast charging and the maximum current is 5A;
Orange: It means that it supports fast charging and has a maximum current of 6A;
