The biggest difference between Type-C and Type-A, Type-B interfaces lies in the range of use. Type-A standard interface is the most well-known type of USB interface, mainly used for computer PCs and chargers, and is currently the most widely used USB interface standard with high popularity. However, this type of interface also has its drawbacks, requiring differentiation between front and back, and the interface volume is relatively large.

Type-C is the latest type of mobile USB interface and currently the hottest type of USB interface. Type-C interface is the standard of USB 3.1, and its advantage lies in its compact design and socket size of only 8.3mm × 2.5mm, fast transmission speed, up to 10Gbps, and also has a strong power output capacity of up to 100W.

The advantage of Type-C interface, which is different from the other two interface types, is that it can support dual sided USB interface plugging and unplugging, and can withstand 10000 repeated lossless plugging and unplugging. It is mainly aimed at small and lightweight portable mobile devices. Nowadays, there is a trend towards Type-C interfaces replacing Type-B and Micro USB.

C-type: USB-C is a newer connector type that is reversible, meaning it can be plugged in either way. It is also smaller and more versatile than its predecessors, supporting higher data transfer rates and power delivery.

A-type: USB-A is the standard rectangular connector that has been around for years. It is commonly used for connecting peripherals such as keyboards, mice, and flash drives to computers.

B-type: USB-B is a larger, square-shaped connector that is used primarily for connecting printers and other larger devices to computers.
