USB Type-C offers a new connector standard that’s very small. It’s about a third the size of an old USB Type-A plug. This is a single connector standard that every device should be able to use. You’ll just need a single USB C to USB C Cable, whether you’re connecting an external hard drive to your laptop or charging your smartphone from a USB charger. Apple’s new MacBook and Google’s new Chromebook Pixel both use their USB-C ports as their charging ports. You could plug your laptop into an external display connected to a power cable, and that external display would charge your laptop as you used it as an external display — all via the USB C to USB C Cable.
