If you’re interested in a new connector standard for your computer, you might be wondering “What is USB-C used for?” USB-C supports a large amount of data and power on a single connector. And, the EU has mandated that all electric devices make the switch by the end of 2022. This standard aims to reduce electrical waste, ensure compatibility between devices, and encourage the use of existing chargers and cables.
USB-C ports have a smaller shape than previous USB iterations. The symmetrical design and reversible orientation mean that you can use one to connect to the other without flipping a cable. This means that you will be able to use any USB-compatible device with a USB-C connector. And it works with all operating systems. Whether you want to connect to your laptop or to a smartphone, USB-C connectors are designed to fit seamlessly.
USB Type C Overview
The 24-pin USB connector system known as USB-C has a rotationally symmetrical connector and is officially referred to as USB Type-C. The connector’s precise capabilities, which are denoted by its transfer specifications, are not to be confused with the name C, which solely refers to the connector’s physical configuration or form factor (such as USB 3.2). The USB-C connector is remarkable for being reversible, allowing plugs to be placed into outlets in either direction.
The USB Implementers Forum (USB-IF) released the USB Type-C Specification 1.0, which was completed in August 2014. Approximately the same time as the USB 3.1 specification, it was developed. It was accepted by the IEC as “IEC 62680-1-3” in July 2016.
It is not required that a device with a Type-C connector supports USB, USB Power Delivery, or any Alternate Modes; the Type-C connector is shared by many technologies while only requiring a small subset of them.
The USB 3.1 specification was replaced by USB 3.2, which was launched in September 2017. It maintains the current SuperSpeed and SuperSpeed+ USB 3.1 data modes and adds two new SuperSpeed+ transfer modes using a two-lane USB-C connector with data rates of 10 and 20 Gbit/s (about 1.2 and 2.5 GB/s).
The first USB transfer protocol standard to solely be supported by USB-C is USB4, which was published in 2019.
Another feature of USB-C is its increased power transfer. Its power transfer capability enables larger devices to charge through USB-C. It can transfer up to 100 watts of power, whereas the older USB standard only supported 5V charging. For this reason, USB-C is used in many devices. So, the next time you charge your device, make sure to use USB-C. If you’re unsure of what USB-C is, read on to find out more about the standard.
In addition to charging, USB-C ports can connect to different peripherals. However, not all USB-C ports are the same. Some are used to charge while others are used for data. Many thin laptops use USB-C for external displays. However, USB-C ports are slimmer than their old video interfaces. If you’re worried that your USB-C port will not work with your device, you can always buy an adapter for USB-C.
Ultimately, USB-C is a great solution to the connectivity problem. While USB-C does face some challenges along the way, it’s clear that this new standard has the potential to change how people use their devices. Eventually, there will be one USB port for everything. And, if it works out for everyone, it will be widely adopted. But, until then, you’ll have to be content with a few devices that don’t support USB-C.
Besides charging, USB-C also offers a wide range of accessories. Power Delivery is a new feature for many USB-C devices, and is officially part of USB technology. USB-C power adapters support up to 100 watts of power. As a result, a USB-C power adapter can charge your iPhone 8 or later model 50% in 30 minutes. But it’s important to note that not all USB-C cables support the same protocols and transfer speeds.
The USB 2.0 Billboard Device Class communicates the supported Alternate Modes with the host OS, and provides user-readable strings that indicate incompatible connections. In fact, USB 2.0 Billboard Device Class does not even require negotiation between a host and a sink – it only appears when the host device is incompatible with the sink. USB 3.2 replaces the USB 3.1 standard and adds two new SuperSpeed+ transfer modes over the USB-C connector. These new transfer speeds can be as high as 10 Gbit/s.
