USB-C stands for Universal Serial Bus Type-C, a computer hardware abbreviation.

Small, oval, reversible 24-pin connector used for charging and data on phones, laptops, tablets, headphones and accessories. One port can carry USB data, video, Thunderbolt and up to 240 W of power, depending on the device and cable.

Example: The iPhone 15 switched to USB-C, so one cable now charges my phone, laptop and earbuds.

Usage notes

The USB Implementers Forum published the connector specification in 2014, and Apple's 12-inch MacBook (2015) was an early adopter. An EU law made USB-C mandatory for phones and many other devices sold from December 28, 2024, and for laptops from April 28, 2026. USB-C names the plug shape only: a USB-C cable may support anything from USB 2.0 to 80 Gbit/s, so check its rating.
