While USB Type-C hubs are commonplace for expanding the ports on laptops and other devices, there are times when you might only need one extra port. Enter single USB-C adapters that offer up a number of connection types including HDMI, DisplayPort, VGA, Ethernet, and more.

The Plugable USB-C Adapters are pretty simple and small in design. Each adapter is roughly 4-inches in length. Of that length, 1 3/4-inches is the adapter portion with the rest being the cable and USB-C plug. As for the adapter, in addition to being under 2-inches in length is about 7/8 of an inch wide and 3/8 of an inch thick. The Plugable logo is printed on the top in an off white.

While the the adapter portion is manufactured from plastic, they are pretty sturdy and solid feeling. Unless you’re stepping on them while wearing shoes, they survive just fine in a pocket in your backpack while on the go. The cable portion is thin and flat and has a nice rubber finish.

Ease of Use

USB-C adapters are a no-brainer to use. Simply plug the USB Type-C end into an open USB-C Thunderbolt port on your laptop or computer. Next, plug in the appropriate cable — HDMI, DisplayPort, VGA, or Ethernet — into the other end and connect it to your monitor or network port.


As mentioned above, I tested the USB-C to DisplayPort, USB-C to HDMI, and USB-C to Gigabit Ethernet adapters. These were all tested using a Dell XPS 15 laptop. In all three cases, the Plugable USB-C Adapters worked as advertised.

I was able to get the stated 4K 30Hz over HDMI, 4K 60Hz over DisplayPort, and was able to max out my internet connection using the Gigabit Ethernet adapter. One thing I will note, however, is that you will need a Thunderbolt 3 or USB-C Alt Mode compatible computer in order to use the HDMI and DisplayPort adapters.

While USB Type-C docks can be pricey, each of the Plugabe USB-C Adapters are only US$14.95. Honestly, if you only need one or two specific port types, these adapters are the way to go given their performance and price.


The Plugable USB-C Adapters offer up the convenience of adding an external monitor or Ethernet connection at an affordable price point.
