Docking station

A docking station is a hub that plugs into a laptop, usually through a single USB-C or Thunderbolt cable, and provides a larger set of ports in return: multiple monitor outputs, several USB ports, wired networking, and often charging power for the laptop itself. It turns a laptop into something closer to a permanent desktop setup each time it connects.

The main convenience is single-cable connection and disconnection. Instead of plugging in a monitor cable, power adapter, mouse, keyboard, and network cable separately every time a laptop returns to the desk, one cable to the dock restores the whole setup at once, which matters most for people who regularly move a laptop between a desk, meetings, and home.

Compatibility is the main thing to check before buying, since not every laptop port supports the same features over the same cable, and driving two or more external monitors at full resolution and refresh rate depends on both the laptop's video output capability and the dock's chipset. Charging wattage also varies between docks, and an underpowered dock can charge a larger laptop more slowly than its original adapter.
