Portable Dock for Mobile Professionals

The Lenovo 40B90100US is a lightweight USB-C travel dock that adds dual-display capability and power delivery to tablets and ultraportables. Weighing 1.00 lbs, it fits in a small bag and targets users who need a productive desktop setup away from a fixed workstation.

Consistent Output During Extended Sessions

The integrated 100 W power adapter keeps the host device charged while driving two external monitors, so performance does not throttle during long workdays. A single cable carries video, data and power, reducing the cable count that typically creates heat and clutter in cramped spaces.

Compact Build with Integrated Power

The enclosure houses the power supply, eliminating the need for a separate brick and making hotel-desk deployments faster. Fixed cables and a small footprint suit frequent pack-and-go cycles, while the 1.00 lb weight adds minimal load to a carry-on. Buyers who require more than two video outputs or legacy port types should consider a larger stationary dock.

Questions about this item

How much heat or noise does the 1.00 lb dock produce when running all day?

The compact 1.00 lb design has no active cooling, so it runs silently and stays cool during extended use.

What host port must my laptop provide for the dock to function?

Your laptop needs a USB-C port that supports video output and power delivery to drive both displays and charge at 100 W.

Will the dock work with an older laptop that only has USB-A ports?

No, the dock requires a USB-C connection with video and power delivery, so legacy USB-A only systems are not compatible.
