Categories : Series
SKU : POR-SER-720
The Plugable TBT3-UD1-83 is a Thunderbolt 3 docking station that expands your laptop's connectivity without adding a power cord. Unlike traditional docks that charge your host, this model is designed for users who don't need host charging—saving cost and desk space. Connect a single 4K@60Hz DisplayPort display, wired Ethernet, and multiple USB peripherals through one Thunderbolt 3 cable. Ideal for business professionals, students, and anyone who wants a cleaner, more efficient desk setup.
This dock focuses on what you need: high-resolution display output, fast networking, and extra ports. With a 4K@60Hz DisplayPort, a passive DP-to-HDMI adapter is included for HDMI displays. The integrated Intel Gigabit Ethernet ensures reliable wired internet for video conferencing and large file transfers.
Two USB 3.0 Type-A ports and one USB-C 3.0 port connect accessories like a mouse, keyboard, or external drive. Stereo audio jacks allow you to plug in headphones and a microphone, keeping your desk tidy.
If your laptop uses a separate charger or you prefer to use the laptop's own power adapter, this dock is perfect. It's also a great solution for desktop systems that already have power but need Thunderbolt expansion.
Compatible with Thunderbolt 3 and Thunderbolt 4 ports (with adapter), this dock works with Windows and macOS. Plug it in, and you're ready to go—no driver installation needed for basic functionality.

For desk setups where the laptop charger is already in place, the TBT3-UD1-83 is a smart choice. It eliminates the extra power circuitry found in charging docks, which can reduce costs and improve thermal performance. With its compact footprint and cable management-friendly design, it helps you maintain a tidy work area. The dock is bus-powered for its host connection, but the included 135W power adapter ensures all ports have ample power for peripherals.
This dock is intentionally designed without host charging. It does not provide power to your laptop, so you must use your laptop's own charger. This reduces cost and heat, making it ideal if you don't need dock charging.
Yes, the dock itself requires its included power adapter to function, but it does not pass power to the host laptop. The adapter powers the dock's ports and features.
First, ensure your system has a Thunderbolt 3 or 4 port. Try reconnecting the cable, restarting your computer, and checking for Thunderbolt software/driver updates. For macOS, check System Report for the Thunderbolt device. If using a Thunderbolt 4 port, use a TB4 cable or adapter.
I needed a way to connect my laptop to a 4K monitor and network without extra adapters. This dock does that perfectly. It's plug-and-play with my MacBook Pro, and the 4K display looks sharp. The passthrough charging isn't included, but that was expected.
If you only need one 4K monitor, this dock is great. It provides stable connectivity and USB ports. However, I wish it offered more than one display output. But for its intended purpose, it works well. The build is solid.
I use this dock with my Dell XPS 13. It connects my monitor, keyboard, and Ethernet with just one cable. It's fast and reliable. The lack of host charging isn't an issue for me since I use the laptop's charger. Great product!
I bought this dock thinking it would work with my MacBook Air M1, but it didn't – the display wouldn't turn on. Turns out Thunderbolt 3 docks are not fully compatible with M1 Macs. I had to return it. Make sure you check compatibility.
This dock is small and unobtrusive, yet it does everything I need. My 4K monitor runs smoothly, and the Ethernet connection is solid. I've had no issues with the dock since I bought it. Highly recommended for a simple setup.
The dock performs well for single monitor use. I like the Gigabit Ethernet and USB 3.0 ports. However, the price feels a bit high for what it offers. But if you need a reliable Thunderbolt 3 dock, this is a good choice.
