USB-C is a reversible connector type that carries data, video and power through one port. It describes the physical plug and socket, not the USB version or speed behind it.
Why it matters
One USB-C port can charge a laptop, drive a monitor and move data, but only if the device, port and cable all support those functions. Phones, tablets, laptops and many accessories have converged on it.
Support for Thunderbolt, DisplayPort video and high-wattage Power Delivery is optional and varies per port.
Example
Two USB-C cables can look identical:
Cable A: USB 2.0 only, 60 W charging
Cable B: 40 Gbit/s data, 100 W+ charging, videoPlugging a 4K monitor into cable A may give no picture, and an external SSD on it will crawl at USB 2.0 speeds.
Common misconceptions
- USB-C means USB 3 or fast. The connector says nothing about speed.
- All USB-C ports can output video. Many cannot.
- All USB-C chargers are interchangeable. Wattage and protocols differ.
