Important USB-C Compatibility Note

A USB-C connector does not automatically guarantee that every docking-station feature will work.

For HDMI/VGA video output, the host USB-C port needs to support the appropriate DisplayPort Alt Mode/video output functionality. For laptop charging, the host device must support USB-C Power Delivery.

Always verify the USB-C capabilities of the laptop, tablet, or other host device before purchasing.
