There’s a new kind of jack in town—well, new as of 2014—called USB-C. This single, tiny connector can carry power, video, audio, and data between electronic gadgets—simultaneously. It can replace a laptop’s power cord, USB jacks, video output jack, and headphone jack. The connector is symmetrical, so you can’t insert it upside-down. It’s identical end for end, too, so it doesn’t matter which end you grab first. USB-C has the potential to charge your gadget faster and transfer data faster than what’s come before, too. And the brand doesn’t matter. My Samsung USB-C cable can charge your Apple MacBook and his Surface tablet. The only question left: Where did it come from? Who invented it? And why?
