USB Type-C is an interface standard. Its biggest feature is that it can support double-sided insertion of the USB interface. At the same time, the data cable supporting USB is also thinner and lighter. The interface shape is shown in the picture below: The USB Type-C interface has the following characteristics: 1. The size of the Type-C interface socket is about 8.3mm × 2.5mm, which is a slim design. The data cable and micro USB are not universal; 2. The USB Type-C supports the double-sided insertion that can be inserted from both sides and can withstand 10,000 times repeated plugging and unplugging; 3. The early Type-C cable can pass 3A electric current and provide a maximum power supply of 100W. After generations of development, the Type-C cable supporting the E-maker chip can carry 5A or even higher electric current and power supply capabilities; 4. Type-C, USB-C and C port are all abbreviations of USB Type-C interface; 5. The Type-C interface has no direct relationship with the direct transmission rate and power supply. Note: 1. USB Type-C, Type-A, and Type-B are only different in the shape of the interface. Type-A is a common USB plug, and Type-B is a plug used by many printers and monitors for data transmission (as shown below); 2. Currently, the Type-C interfaces of most mobile phone manufacturers are USB 2.0 standards. You can check the standards of specific devices by searching the USB Interface Type on the internet.
