Seven-port USB-C hub for laptop users

The WRIARICH BYL-2121U3 adds seven connections through a single USB-C port. It suits people who need HDMI video, SD card access and extra USB-A sockets on a thin-and-light notebook. The compact gray aluminium case measures 5.1 x 1.4 x 0.7 inches and weighs 2.65 ounces. It works with Windows 11, 10, 8.1, 8, 7, macOS, iPad OS, Chrome OS and Linux without drivers.

Passive cooling runs silent with no fan noise

The hub draws power from the host or an attached 100W PD charger to run its ports. No active cooling is present, so operation stays completely silent. The aluminium body dissipates heat during sustained file transfers or 4K video output. Power delivery passes up to 100W through to the laptop while the hub itself consumes only a small fraction.

Aluminium shell with fixed cable and card slots

The unibody aluminium housing resists daily knocks and looks professional on a desk. A short captive USB-C cable connects to the host, so there is no separate lead to lose. Two USB 3.0 Type-A ports sit beside a USB-C data port and a 100W PD input. Full-size SD and microSD 2.0 slots accept cards up to 256G for direct photo import. The HDMI port supports 4K at 30Hz or 1080p for external displays.

Questions about this item

How do I install the BYL-2121U3 hub and what step is often missed?

Plug the hub into a Thunderbolt 3 or USB-C port on your laptop; the step users miss is connecting the 100W PD charger to the hub's USB-C power port so the host can charge while all seven ports are active.

What maintenance or replacement will the BYL-2121U3 need over time?

No scheduled maintenance is required; if the SD or MicroSD 2.0 slots stop reading cards up to 256G, replace the hub as the card-reader controller is not serviceable.

What limit appears first during sustained 4K@30Hz video output with all ports busy?

The HDMI port is capped at 4K@30Hz, so extended sessions at that resolution hit the 30Hz refresh ceiling before the 5Gbps USB 3.0 bandwidth or 100W PD thermal limit becomes a factor.
