The Lenovo USB-C Dock (40B5) – A Smarter Way to Work. This advanced, Windows OS compatible one-cable docking solution lets you work smarter, not harder. It comes with a vast array of ports, next-gen plug and play functionality, and rapid charging capabilities (up to 100W for most USB-C notebooks*). Smart enough to install critical firmware updates automatically, it is ideal for any mixed-PC environment and home office setting, and gives you the freedom and power to do more. The 90-watt power adapter charges ThinkPad and other USB-C notebooks up to 65 watts. For 100-watt charging, an optional slim tip 135-watt power adapter is required (PN: 4X20E50558 (US) / 4X20E505xx) which is sold separately.

Note: Lenovo USB-C and Thunderbolt Docks function with notebooks that support industry standard USB-C Alt-Mode or Thunderbolt protocols through their Type C port. Lenovo USB-C and Thunderbolt Docks support additional features, such as MAC address passthrough, WOL and mirrored power button, on most Lenovo ThinkPad notebooks, but such features may not be available on certain other Lenovo notebooks or non-Lenovo branded notebook systems.”
