Lenovo USB-C to 4-Port USB-A Hub — 42 Grams, No Drivers

4 × USB-A, 5 GbpsBus-powered, 42 gCaptive 138 mm cableUSB-C, USB4 and Thunderbolt hosts

The Lenovo USB-C to 4-Port USB-A Hub, part number 4X90X21427, is a plain and very light port expander: four USB-A ports at USB 3.2 Gen 1 speed, up to 5 Gbps, on the end of a captive 138 mm USB-C cable. It weighs about 42 g, measures 95 × 37 × 12 mm in iron grey, needs no drivers and works with USB-C, USB4 and Thunderbolt 3 or 4 hosts. Lenovo covers it with a 1-year warranty stated in its worldwide accessory datasheet.

Compatibility — check before buying:
This hub is bus-powered with no adapter and no DC socket, so four ports share the host port’s current — bus-powered hard drives are the usual failure case. It has no Power Delivery of any kind: the laptop is not charged and one USB-C port stays occupied. Despite being a Lenovo USB-C accessory it has no video output and no Ethernet, which is the assumption people most often get wrong. The cable is captive and cannot be replaced.

Best For

✓ ThinkPad and other USB-C laptops
✓ Keyboards, mice, dongles and flash drives
✓ Travel kits where weight matters
✓ Corporate fleets that cannot install drivers
✓ Meeting rooms and hot-desks
✓ Adding USB-A ports to a Thunderbolt machine

Key Features

 
Four USB-A ports, nothing to configure
USB 3.2 Gen 1 at up to 5 Gbps on all four ports, driver-free plug and play, which suits locked-down corporate laptops.
 
One of the lightest in its class
About 42 g and 95 × 37 × 12 mm with the cable attached — there is no separate lead and no power brick.
 
Works beyond USB-C
Lenovo lists USB-C, USB4, Thunderbolt 3 and Thunderbolt 4 hosts, so it plugs into almost any current business laptop regardless of brand.

Frequently Asked Questions

Does it have an HDMI output?
No. It is a pure USB-A expander with no video, no Ethernet and no card reader — a common misunderstanding with Lenovo USB-C accessories. For a display, look at Lenovo’s 7-in-1 hub or a docking station.
Will it charge my ThinkPad?
No. There is no Power Delivery, so the laptop keeps its own charger and this hub occupies one USB-C port.
Can I use it with a non-Lenovo laptop?
Yes. Lenovo lists generic USB-C, USB4 and Thunderbolt 3/4 host support, so it works on MacBooks and other brands just as well.
Singular Expert Insight
This is the hub to specify when a business fleet simply needs USB-A ports back and nobody wants to think about it: no drivers, no adapter, Lenovo part number for procurement, and 42 grams. Its honest limits are bus power and the absence of anything but USB-A. If the same laptop needs a monitor, Ethernet or charging, those are dock features — see our docking stations. For 10 Gbps or powered ports, browse our USB hubs. Not sure it fits your setup? Tell us your laptop or PC model and what you want to plug in and we will check it before you order.

Buyer’s Guide

Buy it if

You want four USB-A ports from a USB-C, USB4 or Thunderbolt laptop in the lightest possible form, for input devices and flash drives.

Skip it if

You need video, Ethernet, laptop charging, 10 Gbps, or enough power to run external hard drives.

Also consider

Club 3D CSV-1547 for four USB-A ports at 10 Gbps; Targus ACH226EU for a similar 5 Gbps hub with a 2-year warranty; LogiLink UA0309 for a four-port USB-C hub with a power adapter.
