USB-C, officially known as USB Type-C, was billed as the port to replace them all. It’s a universal, reversible connector that replaces the likes of USB-A, USB-B, Lightning, and Mini DisplayPort. In fact, all other USB connectors were designated as legacy in 2014. While you’ll still see USB-A, USB-B, and their derivatives out in the wild, it’s clear that USB-C is the future. In theory, the USB-C connector gave us everything we wanted — we can now charge and transmit data from headphones, smartphones, laptops, and more with the same cable. So why aren’t we happy?
