One cable to rule them all—that’s the whole point of a Thunderbolt dock. In this video, I tested the top Thunderbolt 4 docks of 2026 to see which ones actually deliver reliable connectivity, enough ports, and the power delivery you need to run a real desk setup. If you’re on a MacBook, an ultrabook, or any modern laptop that’s light on ports, a good dock lets you plug in monitors, Ethernet, storage, and accessories through a single cable and keep your workspace clean. I break down five strong options: Kensington, StarTech, Wavlink, UGREEN, and Sonnet. You’ll see which docks handle dual 4K at 60Hz (and which can push a single 8K display), how the port selection differs (USB-A counts, SD card slots, extra Thunderbolt ports), and what power delivery looks like in the real world—up to 96W for charging more demanding laptops like a MacBook Pro. My takeaway: pick based on your monitor needs, the ports you actually use, and whether you want pro-grade reliability, a sleek premium build, or the best value without unnecessary frills.
