Lenovo USA Gen 2 135W ThinkPad Thunderbolt 3 Dock

The Lenovo 40AN0135US is a ThinkPad Thunderbolt 3 Dock Gen 2 that lets a compatible notebook work like a full desktop without the clutter of multiple cables. One Thunderbolt 3 connection links the laptop to up to two external 4K monitors, a wired network, and a broad range of USB accessories while the included 135 W power adapter keeps both the dock and the computer charged.

Two HDMI ports and two DisplayPort connectors make it easy to drive large, high-resolution screens for tasks such as detailed spreadsheet work, photo editing, or running several business applications side by side. Five USB 3.1 Gen 2 ports support fast external drives, keyboards, or a webcam, and one of those ports supplies always on charging so a phone or headset can top up even when the laptop is away. A Gigabit RJ-45 port offers stable, enterprise grade Ethernet, and a 3.5 mm combo jack handles headsets or external speakers for calls and media.

This dock fits naturally in an open office, a home workspace, or a hot-desk environment where users need to sit down, connect once, and get straight to work. Creative professionals who juggle large files, analysts who rely on multiple monitors, and remote workers who value tidy cable management will all benefit from the streamlined setup. The dock is compatible with select ThinkPad systems such as the T480, X1 Yoga, and P52s; Lenovo maintains an updated list to confirm model support.
