The two most common categories in which USB cables are classified are USB A and USB C. The primary distinction between USB A and USB C is based on the nature of the two cables in relation to their plug-in orientation. In general USB A does not support reversibility in terms of plug-in orientation within the port, whereas USB C supports reversibility and can be plugged in either way regardless of port orientation.

What is USB A?

USB A is the most commonly used type of connector in general, and it has a rectangular shape. It is also known as the most traditional type of USB. It is also known as standard A. This cabling port is commonly found in computer-like devices such as smart televisions, gaming consoles, DVD players, and so on.

What is USB C?

USB C is the most recent type of USB cable in use. It has a square shape. The plug-in reversibility that it provides is the reason for enormous popularity. It is a high-power cable that can handle high-speed data transfer.

Difference between USB A and USB C  | USB A vs USB C:

  • The physical appearance of USB  A is different from USB  C. According to the size of the two cables, it is said that USB- A is large size-wise whereas USB-C appears small.
  • The USB-A cable appears to be wider than the USB-C cable because type C has a smaller shape and is thinner.
  • The output power of the USB-C cable is nearly 100 watts, which is significantly higher than the output power of the USB-A cable.
  • The rate of data transfer is much faster with a USB type C cable than with a USB type A cable. The USB C cable transfers data at a rate of approximately 10 gigabytes per second.
