Universal USB-C Dock for Hybrid Workspaces

The Lenovo USB-C Universal Business Dock 40B30090TA adds seven ports through a single USB-C cable, supporting two external monitors at 3840 x 2160 60Hz via one DisplayPort and one HDMI connection. It is built for professionals who need a compact Storm Grey hub that delivers up to 100W charging to the host notebook when paired with a suitable power adapter.

Display and Power Delivery Limits

Dual 4K output at 60Hz requires a host capable of driving two high-resolution streams over USB-C video alt mode. The dock supplies 65W to the laptop with the included 90W adapter and 96W when a 135W adapter is connected, so maximum charging depends on the brick you use.

Compact Build with Front-Facing Ports

Weighing 0..51 lb and measuring 7.4 x 6.6 inches packed, the matte Storm Grey enclosure fits tight desks and travel bags. Two USB-C 3.2 Gen 2 and three USB-A 3.2 Gen 1 ports sit ready for peripherals, while the slim-tip DC input keeps the power cable low-profile.

Questions about this item

How do I pick between the 90 W and 135 W power adapters for this dock?

With the 90 W adapter the dock delivers 65 W to the notebook; with the 135 W adapter it delivers 96 W. Choose the higher-wattage adapter if your laptop needs more than 65 W while docked.

What does the 100 W charging claim mean when the dock is connected to my laptop?

The 100 W figure is the dock's maximum charging capability; actual output is 65 W with the included 90 W adapter or 96 W with an optional 135 W adapter, so your laptop will receive whichever of those matches the adapter used.

What does USB‑C 3.2 Gen 2 on the two USB‑C ports cap in real use?

Each USB‑C 3.2 Gen 2 port supports up to 10 Gbps data transfer; the two ports share the dock's total bandwidth, so simultaneous high-speed transfers may divide that throughput.
