⚙️ PRODUCT OVERVIEW

The Lenovo ThinkPad Ultra Dock 40A2 is a robust mechanical docking station that turns your ThinkPad into a full desktop setup. With a single motion you dock the laptop and gain instant access to wired network, USB peripherals, and multiple monitors—without reconnecting cables every time.

This unit is used, in very good technical and cosmetic condition. No key for the mechanical lock is included. Power adapter is not included—the dock uses a Lenovo 20V adapter (same standard as Lenovo laptops).
