With easy plug-and-play installation, the dock is ready to go as soon as you connect it, saving you the time and hassle of installing additional drivers or software. For more installation flexibility, you can use StarTech.com mounting brackets (SSPMSUDWM & SSPMSVESA) that are specifically designed for our docks and hubs, to mount your TB3 dock to a desk, wall, or other surfaces to give you the customized setup you need. If you require more security, the built-in K-Slot uses a traditional laptop combination cable lock to ensure your dock stays put. Plenty of Ports This universal Thunderbolt 3 dock (TB3) features plenty of USB 3.0 ports to accommodate up to five USB peripherals and includes a GbE port and audio support:
  • 3 x USB-A Ports (including 1 x Fast-Charge Port)
  • 2 x USB-C Ports (including 1 x Charge Port)
  • 1 x Gigabit Ethernet Port
  • 1 x 3.5 mm Audio/Mic Port
The USB-C ports and one of the USB-A ports will support up to 10Gbps (USB 3.1 Gen 2) data transfer speeds, when the host laptop supports the same. Power Your Laptop While Charging USB-C & USB-A Devices Using a single cable, the dock powers and charges your laptop with 60W Power Delivery, using the included 135W power adapter. The USB-A and USB-C Charge ports can charge your smartphone, tablet or other USB peripherals whether you're working or away from your desk, and even if you disconnect your laptop. Note: Not all USB-C ports support the full functionality of the USB Type-C standard. Ensure that your laptop USB-C port supports DP Alt Mode and USB Power Delivery. If you have any questions around host compatibility and functionality, our Technical Advisors are happy to answer any questions. The TB3CDK2DP is backed by a StarTech.com three-year warranty and free lifetime technical support.
