What Is USB-C

By Tom Brant

USB-C is an industry-standard connector for transmitting both data and power on a single cable. The USB-C connector was developed by the USB Implementers Forum (USB-IF)(Opens in a new window), the group of companies that has developed, certified, and shepherded the USB standard over the years. The USB-IF counts more than 700 companies in its membership, among them Apple, Dell, HP, Intel, Microsoft, and Samsung.

Is USB-C the Same as Micro USB or USB 3.0?

The USB-C connector looks similar to a micro USB or rectangular USB 3.0 connectors at first glance, though it's more oval in shape and slightly thicker to accommodate its best feature: flippability. Like Lightning and MagSafe, the USB-C connector has no up or down orientation.

Can You Go From USB-C to DisplayPort?

USB-C's support for sending simultaneous video signals and power means that you might be able to connect to and power a native DisplayPort, MHL, or HDMI device, or connect to almost anything else, assuming you have the proper adapter and cables. (See below for more on adapters.) The USB-C spec even factors in audio transmissions over the interface, but so far it has not replaced the 3.5mm headphone jack on computers to the same degree as it has on phones and tablets.

Adapters, Cables and USB-C Hubs

USB-C is electrically compatible with older USB 3.0 ports. But because of the shape of the newer port, adapters or cables with appropriate plugs are indeed required if you want to connect anything that doesn't have the USB-C oval shape.

Sometimes a new laptop will come with these; in other cases, you may have to purchase them separately.

The good news, though, is that if you invest in a couple of normal USB-C cables, they will work with anything and everything that supports USB-C, regardless of generation.

Plus, newer docks for PCs and docks for Macs have now widely integrated USB-C. Having only one USB-C port is not a problem: You can find USB-C docking solutions available, both from PC manufacturers like Dell and HP, and from third-party accessory makers like Belkin and CASVIEW. These docks can recharge your laptop, give you access to extra ports (including Ethernet, HDMI, USB 3.0, and VGA), and add support for multiple monitors.
