Product Description

Plugable’s TBT3-UDZ Thunderbolt™ 3 and USB-C Docking Station supports dual DisplayPort or HDMI displays with 96W Power Delivery charging. The TBT3-UDZ offers high-performance expansion of your Thunderbolt 3-enabled Mac or compatible Windows Thunderbolt 3 system while also providing up to 96W of power to charge compatible hosts.

Its unique and exclusive design allows users to connect up to 2 additional 4K displays using either HDMI or DP without the need of external adapters – the first Thunderbolt 3 docking station to offer this functionality. Thunderbolt 3’s massive 40Gbps bandwidth enables you to run your high resolution displays connected through the dock at the full native performance of your system’s graphics processor while also enabling access to your wired network and existing USB peripherals.

Supports connection to wired gigabit Ethernet networks using the integrated 1Gbps network adapter. Provides a combined analog audio input and output jack for connecting stereo headphones and microphone. Provides seven extra USB ports for device connectivity (two 10Gbps 3.2 Gen 2 USB-A in front (one supporting BC 1.2 charging), plus five 5Gbps 3.0 USB-A in back). In addition the dock offers a Micro SD & SD card reader on the front.

The TBT3-UDZ is built upon the latest Intel Titan Ridge chipset, enabling the widest compatibility with Thunderbolt 3 and USB-C laptops on the market. Its dual connectivity removes frustrations from having to pick a docking station for either type of laptop while delivering unrivaled performance.

System Requirements

Full Thunderbolt 3 compatibility with Apple Late 2016/Mid 2017/2018/2019 MacBook Pro, 2018 MacBook Air, 2018 Mac Mini, and iMac Mid 2017/2018/2019 models and many Dell systems which have Thunderbolt 3. Other brands of Thunderbolt 3 systems may work, but not support all of the functionality offered by this dock. USB-C system support varies and will have differing behavior depending on use with Windows or Mac. Please see important details regarding system compatibility, frequently asked questions and more in the sections below.


Thunderbolt 3 is a powerful and complex new technology. System manufacturers have substantial discretion in how they implement various technical elements and features. As a result, compatibility information is complex, and many currently available Thunderbolt 3 systems do not support all the features offered by this Thunderbolt 3 docking station. Some features like PCI-E bandwidth, support for 2 displays over Thunderbolt 3, and the necessary firmware updates for docking compatibility (UEFI BIOS and NVM) are system-specific. Apple and Dell Thunderbolt 3 systems are currently the best-performing, best-supported systems with this docking station.

For details on supported monitor configurations and non-Apple and Dell compatibility, please see additional details below. The dock can provide up to 100W of power to charge the host system, assuming the system supports being charged via its Thunderbolt 3 or USB-C port. Windows systems may require updated NVM firmware, system UEFI BIOS, and Thunderbolt/GPU drivers from the system manufacturer (Apple systems provide this automatically). The ability to add a second display depends on design decisions made by your system manufacturer. Some Thunderbolt 3 systems support a maximum of 20Gbps Thunderbolt 3 bandwidth. The docking station will have reduced functionality if attached to a non-Thunderbolt 3 capable USB-C port.

*USB-C only host systems will have reduced functionality:

  • Compatible Multi-function DisplayPort over USB Type-C (MFDP USB-C) Windows systems without Thunderbolt 3 will be limited to 5Gbps USB 3.2 Gen 1 (5Gbps) performance and:
    2x Extended Displays up to 4K 60Hz (DP 1.4 host with Display Stream Compression (DSC))
    2x Extended Displays up to 4K 60Hz + 4K 30Hz (DP 1.4 host, no DSC)
    2x Extended Displays up to 1080P 60Hz (DP 1.2)
  • Apple USB-C host systems (12″ MacBook Retina models and iPad Pro) are limited to 5Gbps USB 3.2 Gen 1 (5Gbps) performance and up to 1x 4K 30Hz display (2x 4K 30Hz displays mirrored). If two different displays are connected please ensure that if one is lower in resolution that it be connected to the “Display 1” DisplayPort/HDMI and the higher resolution display is connected to the “Display 2” DisplayPort/HDMI

In the Box

Thunderbolt 3 TBT3-UDV docking station, 0.8 meter (~31.5 inches) Thunderbolt 3 40Gbps cable, quick installation guide, and UL certified 20V/8.5A (170W) power adapter (US AC Wall Outlet Plug, 100-240V 50/60Hz) Units sold in the UK or the EU will come with the appropriate power cord.


Q: Why was the TBT3-UDZ charging specification changed to 96W? Will that affect my system?

A: IEC power requirements for this class of device require that charging via USB not exceed 100W for more than 5 seconds. Because charging output from any device will always have some amount of varience, implementing a 96W Power Delivery profile combined with robust circuit design ensures the TBT3-UDZ will meet or exceed these requirements allowing customers to purchase this docking station TBT3-UDZ worldwide. We are unaware of any real-world scenarios where this small change will negatively affect charging behavior, but will certainly provide updates if we learn of any edge cases.
