Best Overall
Plugable Thunderbolt 4 Dock for M4/M5 MacBook Air & Pro (TBT-UDM)
Our verdict: Certified Thunderbolt 4, 100W charging and a driverless setup.
The TBT-UDM is the only certified Thunderbolt 4 dock here, running at 40Gbps with 100W charging. It drives dual 4K HDMI or one 6K display depending on your chip, adds six USB ports, an SD slot and Ethernet, and needs no drivers. That driverless link matters because it carries video natively, with no compression layer.
It ranks first because a certified controller keeps the connection stable, and it is the dock built for the newer Thunderbolt Airs. The DisplayLink hubs below reach more screens, but only by software and a driver install.
Buy it for a newer Air with one high-quality monitor. The caveat: the second display depends on your chip, and it needs a Thunderbolt port, so an older Air without one cannot use it. It also costs the most in the guide.
