Hi there!
Different countries use different power plug standards.
Power cords are NOT included by default.

Package Includes:
1 × Docking Station
1 × 135W Power Adapter (AC power cord is not included)
1 × Data Cable (Cable style may vary slightly by batch, all fully compatible and work perfectly with the dock)

This is a genuine Thinkpad workstation Thunderbolt 3 expansion dock 40AN DK1841  docking station. It is in good cosmetic condition (around 80-90% new) with normal signs of use, and all functions are working normally.

It comes with the original detachable dual-head Thunderbolt cable, and can also work with other laptops with Thunderbolt 3 / 4 or full-featured USB-C ports.
This model is 40AN, the 2nd generation ThinkPad Thunderbolt 3 dock.
It has two power input ports: 65W/135W and 170W/230W.
Important note:
The 65W/135W port must be plugged in first for the dock to work.
It cannot run if only the 170W/230W port is powered.
When using a 135W adapter, the dock can supply 65W charging to your laptop.
One 135W power adapter is included by default.
Built with JHL7440 chip, this dock supports Thunderbolt 3/4 and full-function USB-C devices.
It supports up to 4K triple display output, high-speed USB 3.1 and enterprise management functions.
