USB-C promised simplicity, but has turned into a mystery box of different specs. USB-C has markedly improved the way we use our devices.

The latest and fastest generation of USB, USB4, is capable of bidirectional data transfer rates up to 80 gigabits per-second (Gbps). To put that in perspective, you can transfer a whopping 100 gigabytes in just over 10 seconds at that speed. But don't pick a USB-C equipped device up at random expecting it to have blazing fast speeds. USB-C is not a single specification. Rather, it is a wrapper for one of a number of different specifications, ranging from those that were around when the connector first debuted in 2014 to the latest standards in 2026. When picking up a USB-C device at random, you could end up with a powerful USB4 port, but you could also wind up saddled with a much slower USB 2.0 connection.
