Lenovo USB-C 4 in 1 Travel Hub Gen2 Review 2026

Name: Lenovo USB-C 4 in 1 Travel Hub Gen2
Brand: Lenovo
SKU: GX91R64790

The Lenovo USB-C 4 in 1 Travel Hub Gen2 is a tiny USB-C adapter for people who need one HDMI monitor, two USB-A peripherals, and a headset jack from a laptop bag hub. Model GX91R64790 is listed on Lenovo's US store with a fixed USB-C host cable, two USB-A 3.2 Gen 1 ports rated at 5Gbps, one HDMI 2.0 port, and one 3.5mm combo audio jack that supports CTIA and OMTP headsets. Lenovo rates the HDMI output at 4K at 60Hz, which is the main reason to care about this hub over older budget adapters that stop at 4K at 30Hz. It is not a charging dock, Ethernet adapter, card reader, Thunderbolt dock, USB4 dock, DisplayLink adapter, or multi-monitor workaround. It is a simple four-port travel hub built around native USB-C DisplayPort Alt Mode. The product identity needs a small warning. The queue listed GX91R64790 alongside Amazon ASIN B08VH938FL, but Amazon's B08VH938FL page is an older Lenovo USB-C Travel Hub Gen2 with Ethernet, HDMI, VGA, and a different port mix. The Amazon listing that matches Lenovo's current GX91R64790 4-in-1 hardware is B0F8P21R4C, titled as the Lenovo USB-C 4 in 1 Travel Hub Block with Integrated Cable. During research, that Amazon page showed a 4.5-star rating from 1,193 global ratings, in-stock marketplace pricing around PLN 160, and the same port list as Lenovo's official page: HDMI 4K 60Hz, two USB-A 3.2 ports, one 3.5mm combo jack, and an integrated USB-C cable. Because Amazon groups variant reviews across 4-in-1, 5-in-1, and 7-in-1 Lenovo hubs, the rating is useful as a broad Lenovo hub signal, not as clean feedback for this exact GX91R64790 layout.

Compact 4K60 USB-C hub

Pros & Cons

What We Like

HDMI 2.0 supports a single 4K monitor at 60Hz
Two USB-A 3.2 Gen 1 ports handle 5Gbps accessories, receivers, and flash drives
3.5mm combo jack is useful for headsets on laptops with limited audio ports
Compact Lenovo-branded design with an integrated USB-C cable is easy to keep in a travel bag
No DisplayLink software stack keeps one-monitor setup simple on compatible USB-C hosts

What Could Be Better

No USB-C passthrough charging
Workaround: Use a laptop with a second USB-C charging port, or choose a hub with a USB-C PD input if you need one-cable charging.
Only one HDMI display is supported
Workaround: Use a USB-C MST dock, DisplayLink dock, USB4 dock, or Thunderbolt dock for dual monitors.
No Ethernet, SD card reader, microSD reader, or downstream USB-C data port
Workaround: Choose the Lenovo USB-C 7-in-1 Hub, Lenovo USB-C Slim Travel Dock, or a larger travel dock if those ports matter.
Lenovo officially lists only Windows 10 and Windows 11 OS requirements
Workaround: Mac, Linux, and ChromeOS users should buy from a retailer with easy returns and test HDMI, USB, and audio immediately.
Amazon review data is mixed across multiple Lenovo hub variants
Workaround: Read the selected set-name and port layout carefully before judging reviews or ordering.

Compatibility

Windows (10+)

Lenovo lists Windows 10 and Windows 11 as OS requirements. Full display output requires a USB-C host port with DisplayPort Alt Mode.

macOS

Not listed in Lenovo's official OS requirements for GX91R64790, but the hub should behave like a standard USB-C Alt Mode HDMI and USB hub on compatible Macs. It does not add extra display support beyond the Mac's native limit.

Linux

Not officially listed by Lenovo. USB-A devices and HDMI may work on systems with USB-C DisplayPort Alt Mode and normal Linux graphics support.

ChromeOS

Not officially listed by Lenovo. Chromebooks need USB-C video output for HDMI, and audio behavior may vary by device.

Known Issues

USB-C ports without DisplayPort Alt Mode

No HDMI output

Dual-monitor setups

Only one external display is supported

Laptops that need single-cable charging

No passthrough power

Users who need wired networking

No Ethernet port

Our Verdict

Good

The Lenovo USB-C 4 in 1 Travel Hub Gen2 is best treated as a cleaner replacement for the cheapest HDMI dongles, not as a full dock. The good part is obvious: one compact Lenovo-branded block gives you 4K 60Hz HDMI, two 5Gbps USB-A ports, and a headset jack without asking you to carry a separate cable. That is enough for conference rooms, classroom projectors, hotel TVs, office hot desks, and a lightweight ThinkPad or Yoga setup where you only need a keyboard, mouse, headset, and one monitor. Lenovo's own US page listed it at $44.99 during research with 3.8 out of 5 stars from 18 reviews, and Amazon's matching B0F8P21R4C listing had a much larger but variant-mixed 4.5-star pool. The hardware is modest, but the HDMI 2.0 spec makes it more comfortable on a 4K monitor than the older Lenovo USB-C 7-in-1 Hub, which tops out at 4K 30Hz. The trade-offs are just as clear. There is no passthrough charging, so the hub consumes your laptop's USB-C port without replacing a charger connection. There is no Ethernet, no SD or microSD reader, no downstream USB-C data port, and no second video output. Lenovo's official tech specs list OS requirements as Windows 10 and Windows 11, so Mac, Linux, and ChromeOS buyers should treat support as standard USB-C behavior rather than Lenovo-backed compatibility. The HDMI port also depends on the host USB-C port carrying DisplayPort Alt Mode. If the laptop has a data-only USB-C port, USB accessories may work but the monitor will not. I would buy this hub if the exact job is one 4K 60Hz HDMI screen plus basic USB-A accessories in a small Lenovo adapter. I would skip it for charging, wired networking, card media, dual displays, or any setup where one USB-C port has to do everything at a desk.

Frequently Asked Questions

Does the Lenovo USB-C 4 in 1 Travel Hub Gen2 support 4K 60Hz?

Yes. Lenovo lists one HDMI 2.0 port and a 60Hz refresh rate, and Amazon's matching B0F8P21R4C listing describes HDMI output at 4K 60Hz. The laptop USB-C port still needs DisplayPort Alt Mode support.

Can the Lenovo GX91R64790 charge my laptop?

No. The Lenovo USB-C 4 in 1 Travel Hub Gen2 does not list a USB-C Power Delivery input or passthrough charging. Keep your laptop charger connected separately or choose a different USB-C hub with PD input.

How many monitors does the Lenovo USB-C 4 in 1 Travel Hub Gen2 support?

One external monitor. The hub has one HDMI 2.0 port and does not use DisplayLink, Thunderbolt, USB4, or MST to add extra displays.

What ports are on the Lenovo USB-C 4 in 1 Travel Hub Gen2?

It has an integrated USB-C host cable, two USB-A 3.2 Gen 1 ports rated at 5Gbps, one HDMI 2.0 port, and one 3.5mm combo audio jack.

Is B08VH938FL the right ASIN for GX91R64790?

The queue listed B08VH938FL, but Amazon's B08VH938FL page describes an older Lenovo USB-C Travel Hub Gen2 with Ethernet, HDMI, VGA, and a different port layout. The Amazon page that matches Lenovo's GX91R64790 4-in-1 port layout during research was B0F8P21R4C.

Does the Lenovo USB-C 4 in 1 Travel Hub Gen2 work with MacBooks?

Lenovo's official GX91R64790 page lists Windows 10 and Windows 11 as OS requirements. MacBooks with USB-C video output should usually handle a standard HDMI Alt Mode hub, but Lenovo does not position this model as a Mac dock, and it will not bypass Apple Silicon display limits.
