A truly outstanding utility value. Completely redesigned for a new generation of ThinkPad. It connects to the ThinkPad Pro dock with the included ThinkPad power adapter, providing access to power supply, LAN/Internet, and peripherals such as two external monitors, keyboard, mouse, and printer. This allows you to accomplish more in less time. One of the USB ports on the dock also supports Always-on charging for mobile devices. This means you can charge your mobile phone or tablet even when the notebook is not connected. The ThinkPad power adapter for charging your notebook is included.
