USB Type-C Explained: What is USB-C and Why You’ll Want it
Updated: Sep 12, 2018
USB-C is the emerging standard for charging and transferring data. Right now, it’s included in devices like the newest laptops, phones, and tablets and—given time—it’ll spread to pretty much everything that currently uses the older, larger USB connector.
Though the specifications for USB-C were first published in 2014, it’s really just in the last year that the technology has caught on. It’s now shaping up to be a real replacement for not only older USB standards, but also other standards like Thunderbolt and Display Port. Testing is even in the works to deliver a new USB audio standard using USB-C as a potential replacement for the 3.5mm audio jack. USB-C is closely intertwined with other new standards, as well—like USB 3.1 for faster speeds and USB Power Delivery for improved power-delivery over USB connections.
Type-C Features a New Connector Shape
USB Type-C has a new, tiny physical connector—roughly the size of a micro USB connector. The USB-C connector itself can support various exciting new USB standard like USB 3.1 and USB power delivery (USB PD).
The standard USB connector you’re most familiar with is USB Type-A. Even as we’ve moved from USB 1 to USB 2 and on to modern USB 3 devices, that connector has stayed the same. It’s as massive as ever, and it only plugs in one way (which is obviously never the way you try to plug it in the first time). But as devices became smaller and thinner, those massive USB ports just didn’t fit. This gave rise to lots of other USB connector shapes like the “micro” and “mini” connectors.
This awkward collection of differently-shaped connectors for different-size devices is finally coming to a close. 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 cable, whether you’re connecting an external hard drive to your laptop or charging your smartphone from a USB charger. That one tiny connector is small enough to fit into a super-thin mobile device, but also powerful enough to connect all the peripherals you want to your laptop. The cable itself has USB Type-C connectors at both ends—it’s all one connector.
USB-C provides plenty to like. It’s reversible, so you’ll no longer have to flip the connector around a minimum of three times looking for the correct orientation. It’s a single USB connector shape that all devices should adopt, so you won’t have to keep loads of different USB cables with different connector shapes for your various devices. And you’ll have no more massive ports taking up an unnecessary amount of room on ever-thinner devices.
USB Type-C ports can also support a variety of different protocols using “alternate modes,” which allows you to have adapters that can output HDMI, VGA, DisplayPort, or other types of connections from that single USB port. Apple’s USB-C Digital Multiport Adapter is a good example of this, offering an adapter that allows you to connect an HDMI, VGA, larger USB Type-A connectors, and smaller USB Type-C connector via a single port. The mess of USB, HDMI, DisplayPort, VGA, and power ports on typical laptops can be streamlined into a single type of port.
