HP Universal USB-C Multiport Hub Review 2026 - Specs & Limits

Name: HP Universal USB-C Multiport Hub
Brand: HP
SKU: 50H55UT

The HP Universal USB-C Multiport Hub is a 7-port USB-C travel and desk hub for laptops that need Ethernet, HDMI, DisplayPort, USB-A, USB-C data, and passthrough charging from one short cable. HP sells it under part numbers 50H55AA, 50H55UT, and 50H55PT, with 50H55UT used for the US business-channel listing. The official October 2022 data sheet lists a 150 x 55 x 21.5 mm body, 115 g weight, 30 cm integrated USB-C host cable, two USB-A 3.2 ports, one USB-C 3.2 data port, one USB-C passthrough power port, one HDMI 2.0 port, one DisplayPort 1.2 port, and one RJ45 Gigabit Ethernet port. The headline feature is dual 4K output from a compact USB-C hub, but the footnotes matter. HP lists each video port at up to 4K 60Hz for a single display, while dual-display mode drops to 4K 30Hz and YCbCr422 or YCbCr420 color formats when the host supports DisplayPort 1.4. The hub is not DisplayLink and does not add extra monitor support through a software driver. It relies on USB-C DisplayPort Alt Mode, so the laptop must support USB-C video, and Mac users should expect normal native display limits rather than a DisplayLink-style workaround. Power is also passthrough, not built in. HP rates the hub for up to 65W to the host when you connect a 90W USB-C charger, and the charger is not included. The Amazon listing for ASIN B0B4BHJT1C was live during research with a 4.3-star rating from 10 reviews. CDW listed the product at $147.99 and showed mixed user comments: buyers liked the portability and MacBook compatibility, but one complained that HP did not make the separate charger requirement obvious enough. Newegg showed the same HP power disclaimer and no direct customer reviews for its listing. That split between clear official specs and thin buyer feedback is why this review treats the hub as practical, but not especially exciting. This is a useful branded USB-C hub if you need wired Ethernet and two basic 4K displays, but it is not a full desktop docking station.

USB-C Business Hub

Pros & Cons

What We Like

HDMI 2.0 and DisplayPort 1.2 outputs can drive two office monitors from one compact hub
Gigabit Ethernet is built in, unlike many travel-focused USB-C hubs
30 cm integrated cable gives more placement flexibility than short dongle pigtails
65W USB-C passthrough charging works with a suitable 90W charger
HP lists Windows, macOS, and ChromeOS support
HP business manageability support includes PXE Boot, Wake-on-LAN, LAN/WLAN switching, and MAC Address Pass-Through

What Could Be Better

Dual 4K output is limited to 30Hz, not 60Hz
Workaround: Use one 4K 60Hz monitor, lower the resolution, or choose a Thunderbolt, USB4, or DisplayLink dock for smoother dual-display setups.
Host connection is 5Gbps USB-C rather than 10Gbps USB-C or Thunderbolt
Workaround: Use it for normal peripherals and office displays, not high-speed storage plus multiple monitors.
Power adapter is not included
Workaround: Bring a 90W USB-C charger if you want HP's full 65W host passthrough rating.
No SD card reader or audio jack
Workaround: Use a separate card reader or audio adapter, or choose a larger dock with media ports.
No DisplayLink support for bypassing Mac multi-monitor limits
Workaround: MacBook users who need more displays than the laptop supports natively should choose a DisplayLink dock.
Public feedback is limited and includes some network-drop complaints
Workaround: Update firmware through HP tools where available and buy from a retailer with an easy return policy.

Our Verdict

Good

The HP Universal USB-C Multiport Hub is best for people who want one small HP adapter to cover conference rooms, hot desks, and light home-office setups. The port mix is better than most tiny travel hubs because it includes both HDMI and DisplayPort plus Gigabit Ethernet. A 30 cm host cable is also more forgiving than the very short pigtails on many compact hubs. For a Windows laptop with USB-C DisplayPort Alt Mode, this can run one 4K 60Hz monitor cleanly, or two 4K monitors at 30Hz if the laptop has enough DisplayPort bandwidth. It also supports HP business features such as secure firmware updating, PXE Boot, Wake-on-LAN, LAN/WLAN switching, and MAC Address Pass-Through, which makes it more interesting for fleet laptops than a generic Amazon dongle. I would not buy it expecting Thunderbolt-dock behavior. The host link is USB-C at 5 Gbps, Thunderbolt laptops fall back to USB-C speeds, and dual 4K comes with the 30Hz and chroma-subsampling caveat from HP's own data sheet. That is acceptable for static office apps, spreadsheets, and admin dashboards, but it is not the right fit for video work, gaming monitors, or anyone sensitive to cursor movement at 30Hz. The 65W power limit is fine for many 13-inch and 14-inch laptops, but you need to bring a 90W USB-C charger, and mobile workstations may still drain under load. The user feedback is thin and a little uneven. Amazon showed only 10 reviews at 4.3 stars, Newegg had no product reviews, CDW had both positive portability comments and frustration around the power-adapter requirement, and Reddit had at least one sysadmin thread about network drops on this model. That is not enough to call it unreliable, but it is enough to keep the score conservative. Buy it if you need a compact HP-compatible USB-C hub with RJ45 and dual basic displays. Skip it if you need 4K 60Hz on two monitors, 10Gbps data, card readers, audio, included power, or DisplayLink-style multi-monitor support on base-model MacBooks.

Frequently Asked Questions

Does the HP Universal USB-C Multiport Hub support dual monitors?

Yes, but with limits. HP lists HDMI 2.0 plus DisplayPort 1.2 dual-display support up to 3840x2160 at 30Hz when the host supports DisplayPort 1.4. For one monitor, either video port can reach 3840x2160 at 60Hz.

Does the HP 50H55UT need DisplayLink drivers?

No. The HP Universal USB-C Multiport Hub does not use DisplayLink or Silicon Motion. It uses the laptop's native USB-C DisplayPort Alt Mode video output, so the host USB-C port must support video.

How much power can the HP Universal USB-C Multiport Hub pass to a laptop?

HP lists up to 65W to the host when the hub is connected to a 90W USB-C charger. The USB-C charger is not included with the hub.

What ports are on the HP Universal USB-C Multiport Hub?

The hub has two USB-A 3.2 ports, one USB-C 3.2 data port, one USB-C passthrough power port, one HDMI 2.0 port, one DisplayPort 1.2 port, one RJ45 Gigabit Ethernet port, and an integrated USB-C host cable.

Does the HP Universal USB-C Multiport Hub work with MacBooks?

HP lists macOS support, and it should work as a native USB-C hub on MacBooks with USB-C video support. It does not use DisplayLink, so it will not bypass Apple Silicon external-display limits.

Who should buy the HP Universal USB-C Multiport Hub?

Buy it if you want a compact HP USB-C hub with Ethernet, HDMI, DisplayPort, USB ports, and 65W passthrough charging for office use. Skip it if you need dual 4K 60Hz, included power, card readers, audio, or high-speed Thunderbolt storage bandwidth.
