Except for Apple phones, the charging interface of almost all Almost all phones has become type-c, followed by laptops. What's the good about type-c interface?

There are three types of USB interfaces with different appearances, type-a, type-b, and type-c. Type-a is the most widely used interface standard in computers and electronic accessories. Most mice, USB drives, and data cables use this type of interface, and its size is also the largest. Type-b is generally used for devices such as printers and scanners. Type-C has a much smaller volume than type-a and type-b, and there is no difference in the direction of the interface. It can be easily plugged in and out, and can be applied to both PC and external devices (such as mobile phones). With the gradual maturity of type-C technology, various newly launched electronic products are also equipped with full type-C interfaces.

In addition to the convenient front and back pluggable interface design, the type-c interface has stronger power supply capacity. Compared to other USB interfaces with 0.5A and 0.9A, the type-c interface can carry higher current and often supports high-power charging. Most smartphones achieve fast charging through type-c, greatly saving charging time. The type-c interface has a faster data transmission speed, up to 40Gbps, and can be used for bidirectional transmission, which can serve as both input and output interfaces. The type-c interface has good compatibility. It has more outlets. It can transmit 4K UHD video with DP (digital video interface) and HDMI (high-definition multimedia interface cable). It can also be used to project the screen without Docking station (an external device that enables the laptop to connect to the display in a one-stop manner).
