The Plugable USB-C Docking Station with Power Delivery (UD-CA1A) increases the functionality, usability, and flexibility of supported USB-C systems like the Dell XPS 13 and XPS 15. Power up your productivity with the ability to add an external HDMI display while simultaneously providing up to 60W of power to charge your system and expanding your connectivity with Gigabit Ethernet, audio input/output, and five USB ports to connect your peripherals. All through a single USB-C cable. The HDMI and charging functions of the UD-CA1A are powered by one of USB 3.1’s most exciting new features: support for "Alternate Modes" and Power Delivery. Alternate Modes allow certain non-USB data and protocols (such as native video) to be sent over a USB-C cable, while Power Delivery enables you to power and charge a supported system without the need for the laptop's proprietary charger. Support for these features must also be built-in to the system being used, so please see the important additional compatibility details in the sections below. Important Compatibility Details Not all USB-C ports are created equally USB-C is a new standard with much versatility. As a result, compatibility information is complex. Some USB-C systems support Alt Mode video output, while others do not. Some can be powered and charged via USB-C Power Delivery, while others do not. Please refer to your user manual or system manufacturer to verify that the USB-C port supports video data and charging. USB 3.1 Type-C Compatibility Many current USB-C systems which do support Alt Mode video output do not support charging via USB-C. Systems such as this will output video from the dock, but will still need their proprietary OEM chargers. For example, some systems will display a warning during boot if connected to a 85W power adapter rather than a 130W power adapter. These systems may still charge, but at a slower rate.
