It is thought that our picture shows the various devices that can be supported by the USB connection.

Laptop Buying Guide (2024): How To Choose The Right Pc (step By Step Guide)

The first rectangular USB-A port solved a big problem by helping us connect all our devices with a common connector. Today’s oval USB-C shape is fast becoming the global standard because it provides faster data transfer, power, and video transfer in a smaller package.

However, USB-C’s additional capabilities have created new problems for consumers. Manufacturers of peripheral devices can use different technologies in the USB-C image. So now, many devices that are represented by a square, a circle, and a triangle in the USB symbol may have a USB-C connector that is designed to be different. Some USB-C connections will charge the host, support video, support Thunderbolt3 technology, or simply support data. If you’re confused, don’t worry – there’s a way to figure out what type of technology is in the USB-C connector. is here to demystify USB-C by explaining its features and showing you how to read the various USB symbols.

There are many things to like about the USB-C connector. To start, it is good to know that the name USB-C describes the physical body of the connector, not the technology in the port. USB-C has been designed to fit a lot of capacity into a small package, eliminating the need for drawers of cables with different components. Its oval shape is thin, flat, and compact enough to fit in slimmer devices like tablets and phones as well as in larger devices like laptops. The USB-C connector is symmetrical and reversible, so it fits the way you plug it in.

Most importantly, USB-C is a power connector that fits multiple pins (pipes that transfer data, power, and video) into its thin shape. But here’s the problem: not all devices use all the same pins. For more information on how to use pins, see this presentation from VESA.

It is important to know that the USB-C shape is universal (once you know what to look for, you can easily choose the oval USB-C connector out of a line), but the device internal usage can vary greatly from device to device. Some devices sport USB-C connectivity with a combination of power delivery, data, and video transfer. Others have a USB-C port that only supports data and video, power and data, or just data alone. Even in a product store, different devices may have USB-C ports with different technologies. This can be confusing if you don’t know what you’re looking for, so let’s break it down.

When it comes to purchasing accessories for a device, it is important to understand exactly what the device’s USB-C connection can support. No one wants to go through the excitement of unboxing a new product only to find out that it won’t work with your device. is here to help you find the way behind the anger. If you get close to your device’s USB-C port, you can see a symbol that shows the technology and its capabilities.

However, not all devices include a symbol to help you determine the technology inside – some manufacturers prefer to leave these symbols out altogether. If your device is not registered (or if you just don’t have time to decipher the hieroglyphic USB symbols), you can contact the manufacturer or just ask directly at DockGuy@. We strive to be an Expert, and are here to help you manage your desk environment, from stations to ergonomic and locking devices that promote health and efficiency Safe.

Now that you’ve got the lay of the land, you’ll see that it’s not too difficult to navigate the different USB-C functions after all.
