At present, our common Android device data interfaces are micro usb and type-c. The main differences between the two are in appearance, data transmission and charging efficiency. In terms of appearance, the micro USB interface is narrower than the type-c interface, with different sizes at the upper and lower ends, which can be divided into positive and negative directions. The type-c interface is a regular rounded rectangle, which does not have a square direction, making it more convenient. In terms of transmission speed and charging efficiency, type-c interface has faster transmission speed, higher maximum output power and higher charging efficiency.

Many mobile phone charging interfaces have been replaced with type-c interfaces, and computers and USB drives are also popularizing type-c interfaces. Compared to the coexistence of various interfaces in the past, it is awkward to find suitable charging cables everywhere when mobile phones and computers run out of power. A unified interface is simply too friendly. Why do you favor the type-C interface so much? The most common understanding is that there is no need to distinguish between pros and cons, and charging is faster. After all, who can refuse the efficiency of "charging for five minutes and talking for two hours"? With the development of network technology, mobile phones are increasingly dependent on the network. The faster the network speed, the more problems the phone needs to deal with in the same period of time, and the greater the power consumption. At present, to reduce the battery consumption of mobile phones, two approaches can be taken: one is to update the phone battery, and the other is charging technology.

Technical features: On January 7, 2013, the USb3.0 promotion organization announced at the Consumer Electronics Show that the first batch of devices with a transmission rate of 10GB/s will be launched in 2014. The USB interface of such products adopts the standard of USb3.1, that is, the size of the type c interface socket end is about 8.3mmX2.5m slim design, which can withstand 10000 times of repeated plugging and unplugging; The standard specification connecting wire equipped with a type C connector can pass a current of 3A-5A, and also supports USB PDs with USB power supply capacity, which can provide up to 100W of power.
