Compatible 40AN Dock Power Supply

This AC adapter is built for the Lenovo DK1841 ThinkPad Thunderbolt 3 Dock Gen 2. It replaces a lost or faulty original unit so the dock can deliver power and data to a connected notebook. Buyers who need a different connector or voltage should verify their dock model before ordering.

Simple Plug-In Installation

The adapter connects directly to the dock’s power input and a standard wall outlet. No drivers or configuration are required. The main risk is ordering the wrong part; the supplier notes that buyers must confirm the exact device model to avoid a mismatch.
