rectangular) and a USB specification which reveals how capable it is.

However, USB 3.2 has two 10Gbps lanes and is thus capable of achieving 20Gpbs.īoth USB-A and USB-C ports can support USB 2.0 to 3.2, which makes the whole thing a bit confusing since a USB port has both a connector type (USB-C vs. USB 3.0 can achieve transmission speeds of up to 5 Gigabits per second (or 5 Gbps), whereas USB 3.1 can achieve up to 10 Gbps. Most of us will never care enough to tell the difference between USB 3.0 and USB 3.2, but it's nice to know how it all works.

SuperSpeed and SuperSpeed+ support (through USB 3.0 and higher) allows for faster data transfer speeds. Support for Power Delivery lets you charge large electronics like laptops via USB-C. With an adaptor, USB-C is backward compatible with USB-A and with various connection types, including HDMI. Because of the connector’s symmetrical design, you don’t need to worry about which way you insert the cable into a port (thank goodness). USB-C ports are smaller and thinner than USB-A.
