Questions about this item

What cables and accessories come in the box with the Lenovo 40AN0135US dock, and what must be purchased separately?

The dock includes a Thunderbolt 3 cable and 135 W power adapter. No video cables or extra adapters are supplied, so buy HDMI or DisplayPort cables separately for each monitor.

Which version of the ThinkPad Thunderbolt 3 Dock Gen 2 should I choose for a ThinkPad T580 versus a P52s?

Both the T580 (20L9, 20LA) and P52s (20LB, 20LC) are on the supported list, so the single 40AN0135US model works for either machine.

What does the 135 W rating mean when the dock is connected to my laptop?

The 135 W adapter powers the dock and delivers up to 135 W of charging to the attached laptop over the Thunderbolt 3 cable, while also running all connected peripherals.
