What is USB C Used for?

USB-C is the latest version of the USB standard. Nowdays, USB-C has taken over at work, at home and at school.

USB Type-C ports are now found on all manner of devices, from simple external hard drives to high-end laptops and the latest smartphones. While every USB-C port looks the same, not every one offers the same capabilities.

So what is USB C port and cable used for?

Data Transmission and Datasync

Most USB-C ports are built on the second-generation USB 3.1 data-transfer standard.

On many laptops and desktops, the USB-C specification also supports Intel’s Thunderbolt 3 data-transfer technology. A USB-C port equipped with Thunderbolt 3 can push data speeds to a theoretical limit of 40Gbps.

Data transfer over USB-C also includes connecting to a wired Ethernet network via an adapter, since most USB-C computers are thin and don’t have a standard Ethernet port.

Power Charging

USB-C cables are used to transfer power — they’re commonly used to charge portable devices, smartphones, laptops, and even security cameras.

Some popular devices that use USB-C cables are the Nintendo Switch, MacBook Pro, and Samsung Galaxy line of phones.

USB C PD cables can charge laptops and other high-wattage devices, which will let a USB-C cable deliver up to 100 watts.something impossible for the older USB standards.

Video and Audio transmission

Many thin laptops also use USB-C ports for connecting to external displays in addition to charging and data because it is slimmer than older video interfaces such as VGA and HDMI.

USB Type-C ports can 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, assuming you have the proper adapter and cables.

The USB-C port 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.

Make sure to check the specs on any PC you’re thinking of buying, because not all USB-C ports are alike. So far, every one we’ve seen supports both data transfers and connected-device power delivery over USB-C (though not necessarily charging of the host device).
