But, you can also have a USB-C cable that is as slow as the ancient USB 2.0 spec. This means they can transfer an HD movie in about five seconds, around 10 gigabits per second.
Some USB-C cables are USB 3.1 Gen 2 cables. A USB-C cable can be limited to either USB 3.1, 3.0, or 2.0 speeds. The protocol, or specification, determines what the cable can transfer and how fast it can send it. Even though two cables can have the same physical connector, what's happening on the inside can be very different. The USB-C name refers to the physical shape of the connector, not the protocol. But there's one big issue holding it back. It was supposed to be a universal connector, bridging together phones, computers, power supplies, and accessories. How come this USB-C cable costs so much more than that one? And why does this cable transfer data and power slower than that one? How can two cables that look identical be so different?Įven though it's been around for a few years, there's still a lot of confusion surrounding USB-C. Finally, a universal connector has arrived. It can transfer data, power, video, audio, and it's not limited to one manufacturer, like Apple's Lightning cables. You might have seen this type of charger on some of your newer devices.
