Some knowledge about USB Type-C interface
I. What is USB Type-C interface?
A. Definition of the USB Type-C interface
USB Type-C interface is a digital signal transmission interface with a new plug design, which can be inserted on both sides without distinguishing the direction. Its interface size is smaller than the traditional USB-A interface and larger than the USB-B interface, which is more suitable for use in various application scenarios. At the same time, the USB Type-C interface also supports a variety of protocols and data transmission speeds, and can achieve high power charging.
Specifically, USB Type-C is a new interface standard introduced by the USB Implementers Forum (USB-IF). It not only supports high-speed data transmission and fast charging, but also has the advantages of reversible plug, unified standard, and strong scalability. Compared with the traditional USB interface, the USB Type-C interface is more intelligent and convenient, and has become the most widely used interface in modern digital devices.
B. Advantages of the USB Type-C port
1.Reversible plug design
The USB Type-C interface uses A new reversible plug design, which is significantly different from the traditional USB-A interface and USB-B interface. The structure of the plug is more complex, but also more compact, using a 24-pin connection, can achieve higher transmission speed and charging power. The reversible plug design is one of the most significant features of the USB Type-C interface. It not only facilitates the use of the user, but also reduces the user’s troubles when inserting the interface, and also reduces the damage rate of the device and the interface. More importantly, this design also provides more room for the expansion of more functions in the future, and also makes future devices more intelligent and convenient.

There are many factors affecting the data transmission speed, mainly including the performance of the device itself, the material and length of the connecting cable and other factors. At the same time, it is also necessary to use the same high-speed USB Type-C interface between the device and the computer in order to give full play to the advantages of its transmission speed.
3. Higher charging power
The USB Type-C interface supports Power Delivery technology, which can realize high-power charging. The advantage of Power Delivery technology is that it can be intelligent power distribution, according to the needs of different devices, adjust the size of the current and voltage, so that faster charging. In addition, this technology can also support two-way power supply, both to charge the device, but also through the USB Type-C interface to transfer power to other devices. The charging power of the USB Type-C interface depends on the power requirements of the connected device, the length and material of the cable and other factors. If the connected device requires higher power, then it also needs a more powerful power adapter to work with it, otherwise it will not be possible to achieve fast charging.
