Home/Categories/Hubs & Docks
USB-C hubs for the laptop bag and docking stations for the desk — checked for the things that trip people up: which ports carry video, how many monitors your laptop can actually run, and how much charging power reaches it.
Compatibility comes first: the host connection a hub needs (USB-C with DP Alt Mode, USB4 or Thunderbolt), how many displays it really supports on Windows and on a Mac, and how much power passes through to the laptop. Then data speed, port selection, heat and long-term reliability from owner reviews.

A hub is a small, bus-powered adapter that adds a few ports, usually one HDMI, some USB and a card reader, and it travels in a laptop bag. A dock stays on the desk, has its own power supply, runs more monitors, adds Ethernet and charges your laptop and other devices.
Only if two things are true: the hub has a video port (HDMI or DisplayPort), and your laptop’s USB-C port supports video (DP Alt Mode, USB4 or Thunderbolt). A USB-C data port on a hub usually does not carry video.
It depends on the chip and the dock. Base M1, M2 and M3 MacBooks support one external display. Docks that rely on MST mirror the second screen on macOS, so for two extended screens on a Pro or Max chip look for a Thunderbolt dock that lists macOS dual-display support.
Less than the charger’s rating. Hubs keep around 15W for themselves, so a 100W charger usually delivers about 85W to the laptop. Docks list a separate host-charging figure, often 85W to 100W.
