It can be asked why, after all of these years of using USB-A connections, do we need USB-CPD? The answer is a resounding “YES”. USB-A was helpful in providing a pathway to transfer information, but when compared with USB-CPD, it is like comparing a dirt road with a six-lane highway. The USB-C is compatible with the USB-A interface. Smaller and more slender than the Type A, USB-C is designed with a reversible tip and no “up” or “down” orientation. This means you don’t need to flip the connector around several times to fit it correctly into the port. It is sleek enough to be used in small, thin devices such as smartphones, but also capable of handling enough power to charge larger devices like laptops and computers. USB-A and USB-C are like one-way streets that can handle light traffic.
