Compact 4-in-1 USB Hub

The WRIARICH A2N3USB3 adds a gigabit RJ45 port and three USB 3.0 ports to a single USB-A socket. It suits laptop users who need wired networking and extra peripherals at the same time. All four ports operate simultaneously without requiring an external power supply.

Passive Cooling and Low Power Draw

The adapter runs without a fan, so it stays silent during normal use. Power is drawn directly from the host USB 3.0 connection, keeping cable clutter to a minimum. The compact 5.1 by 1.4 by .7 inch enclosure dissipates heat through its aluminium casing.

Driver-Free Operation Across Platforms

Windows 11 through XP, macOS, Linux, Chrome OS and iPad OS recognise the device automatically. No bundled software or configuration utility is included in the package. Buyers who need managed-switch features or USB-C host support will not find them here.

Questions about this item

How do I install the WRIARICH A2N3USB3 adapter and what step is often missed?

Plug the USB-A connector into the host, connect the RJ45 cable, then wait for the OS to load the driver automatically; the step often missed is confirming the gigabit link LED lights up before transferring data.

What maintenance or replacement will the WRIARICH A2N3USB3 need later?

No scheduled maintenance is required; if the USB-A plug or RJ45 port wears out from repeated insertion, replace the entire adapter.

What limit appears first on the WRIARICH A2N3USB3 during sustained use?

The single 5 Gbps USB 3.0 uplink caps combined throughput of the 1000 Mbps Ethernet port and three USB 3.0 ports when all four run heavy traffic together.
