Portable four-port USB-C hub

The Lenovo 4X90X21427 adds four USB-A 3.0 ports to a single USB-C connection on a notebook. It is aimed at users who need to attach drives, keyboards, mice or optical drives simultaneously. The aluminium-coloured enclosure weighs 42 grams and measures 9.2 by 1.5 by .5 inches.

Driver-free setup with power limits

The hub works immediately on supported USB-C hosts without extra software. Total downstream current is capped at 3 A, so bus-powered hard drives or multiple high-draw peripherals may not spin up reliably. Actual transfer speeds vary by host and cable quality and can fall below the 5 Gbit/s, 10 Gbit/s or 20 Gbit/s theoretical maxima.

Four USB 3.0 Type-A ports

The decisive specification is the four USB 3.0 Type-A downstream ports fed by one USB-C upstream link. Buyers who need USB-C downstream ports, video output, Ethernet or power delivery to the host should look at a different dock.

Questions about this item

How can I confirm the Lenovo 4X90X21427 hub is working after I plug it into my USB-C notebook?

Connect a USB drive, keyboard, mouse and external DVD burner to the four USB-A ports; if each device is recognised and transfers data, the hub is operating as intended.

What comes in the box with the Lenovo 4X90X21427 and what must I purchase separately?

The package contains the hub itself with its integrated USB-C host connector; no extra cables or power adapters are included, so buy any additional USB-A cables you need.

Which version of the Lenovo 4X90X21427 should I choose for four USB 3.0 ports in an iron-grey finish?

This single model provides exactly four USB 3.0 ports in iron grey, so there are no alternative versions or capacities to select from.
