USB Type-C Reaches New Consumer Devices
Published:
USB Type-C began appearing on major consumer devices in 2015, including Apple’s 12-inch MacBook and Google’s Chromebook Pixel. The small reversible connector was designed to replace several older USB plug shapes.
The important change was not just convenience. USB-C was a connector standard capable of carrying USB data, charging power, DisplayPort video through alternate modes, and other protocols. USB Power Delivery could negotiate higher voltages and currents, allowing the same cable family to charge devices far larger than a phone.
The transition was confusing because identical-looking USB-C ports and cables could support very different data rates, charging levels, and video features. The connector eventually became universal, but the underlying protocol complexity never disappeared.
