The Plugable UD-CAM dramatically increases the functionality, usability, and flexibility of supported USB-C systems like the 2015 and later 12" MacBook Retina with USB-C, late 2016/2017 MacBook Pro with Thunderbolt 3, Dell XPS, Precision, and Latitude systems with Thunderbolt 3, and the Microsoft Surface Book 2. Power up your productivity with the ability to add an external HDMI display while simultaneously providing up to 85W of power to charge your system and expanding your connectivity with Ethernet, audio input/output, and four USB ports to connect your peripherals. All through a single USB-C cable! The functionality of the UD-CAM Mini Dock is powered by two of USB 3.1''s most exciting new features: support for Alternate Modes and Power Delivery. Alternate Mode allows 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 a traditional proprietary OEM 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. The extended charge and power availability with the UD-CAM (at a total of up to 85W available) ensures that your device will stay charged, powered, and ready to go for any intensive application usage!
