1. Regarding the "forward and reverse insertion" function

The emergence of USB Type-C has solved the global problem of "USB can never be plugged in properly". The USB Type-C uses the same touch points internally, so users no longer need to distinguish between the front and back of the USB, just like the Apple Lightning interface, which can be inserted in both directions.

Apple also happens to play the role of a contributor in the development of USB 3.1 standards, leading the specifications of connectors and pins together with other system manufacturers.

2. About 100000 times of plugging and unplugging

But does the physical design of USB Type-C seem fragile?

In theory, this type of interface can withstand 100000 plug and unplug cycles, and with proper process control, there can be more. However, the biggest weakness is the end of the metal connectors used for male and female ports. The Type-C interface is compact in size and does not have sufficient protection around it like the Type-A. Therefore, if the data cable is bent back and forth during repeated insertion and removal, it is easy to cause deformation or damage to the interface of the motherboard or one end of the data cable.

3. Power supply capacity: up to 100W

Type-C also supports USB Power Delivery specifications, with a maximum power supply of up to 100 watts.

The SB Power Delivery specification will increase power delivery through USB cables and connectors, expanding the cable bus power supply capability in USB applications. This specification can achieve higher voltage and current, with a maximum transmission power of up to 100 watts. In addition, the power transmission source can be switched without changing the cable direction. This specification is compatible with existing cables and connectors, and can coexist with USB Battery Charging 1.2 specification and existing USB bus powered applications.

It should be noted that the 100W power supply capacity is not limited to USB 3.1, but can also be achieved with USB 3.0 and USB 2.0.
