Enhance productivity with a 3-port USB hub
Some USB Type-C laptops, tablets and computers have only one port for external connectivity, which
limits the number of peripheral devices you can use. This USB-C Ethernet adapter features a built-in hub
with three USB Type-A ports, giving you the freedom to attach additional devices, such as a USB mouse
or flash drive. You can expand the number of USB ports you have to enhance your productivity.
Gain easy portability
Travel-sized and self-powered, this USB-C network adapter and hub provides easy portability, tucking
easily into your laptop bag and eliminating the need to carry a separate Gigabit Ethernet adapter and
USB-C to USB-A hub. It’s ideal for mobile use, providing you with wired network connectivity wherever
you go, and letting you plug in extra USB peripheral devices. It also has a built-in USB-Type-C cable so
it’s always there when you need it.
Power and charge as you work
The USB-C network adapter lets you power and charge your laptop as you work, while powering the hub
at the same time. The adapter supports Power Delivery 2.0, so instead of carrying multiple power
adapters, you can use your laptop’s USB-C power adapter to power both your laptop and network
adapter. Note: just make sure your laptop’s USB-C based power adapter supports USB Power Delivery
2.0.
Install it with ease
Get up and running quickly. Simply plug the adapter into the USB Type-C™ port on your laptop and
connect to your network. It automatically installs once you connect it, and works with a wide range of
operating systems such as Windows®, macOS, Linux® and Chrome OS™.
