Hub USB GRAUGEAR G-HUB31L-A — host USB 3.2 Gen 1 Type-A, 3 porte USB 3.2 Gen 1 Type-A + RJ-45, 5000 Mbit/s

The GRAUGEAR USB Hub G-HUB31L-A expands a single USB 3.2 Gen 1 (3.1 Gen 1) Type-A host port into three USB 3.2 Gen 1 Type-A downstream ports and one RJ-45 Ethernet port. The compact adapter features an aluminium and plastic housing, a 0.15 m cable and supports data transfer up to 5000 Mbit/s (USB 3.0 / 5 Gbit/s) while offering a wired Gigabit Ethernet connection for network access. A Type-C adapter is included to enable use with Type-C host ports.

Advantages

The G-HUB31L-A provides simultaneous expansion of USB connectivity and wired LAN access without requiring external power. Its aluminium body contributes to a lightweight but durable design suitable for mobile use, and support for USB 3.2 Gen 1 enables high-speed transfers for storage devices and peripherals. The integrated RJ-45 port supplies reliable Gigabit Ethernet connectivity where Wi‑Fi may be slow or unavailable.

Suitable for

• Adding multiple USB Type-A peripherals (external drives, keyboards, mice) to a laptop or desktop
• Connecting to wired Gigabit Ethernet networks for stable internet or local network access
• Working on the go where compact, portable USB expansion is required
• Short cable setups where a compact hub is preferred over longer docking stations

When it may not be suitable

This hub uses a short 0.15 m integrated cable and is designed for compact, near-host connections; it is not intended to replace full docking stations with multiple display outputs or extensive port arrays. The hub does not supply high-power charging for power-hungry devices and may not provide sufficient power for multiple bus-powered hard drives connected simultaneously without their own power sources.

Key specifications

• Host interface: USB 3.2 Gen 1 (3.1 Gen 1) Type-A (with included Type-C adapter for Type-C hosts)
• Downstream ports: 3 × USB 3.2 Gen 1 Type-A
• Network port: 1 × RJ-45 Gigabit Ethernet
• Maximum USB data transfer rate: up to 5000 Mbit/s (5 Gbit/s)
• Wired Ethernet speed: up to 1000 Mbit/s (1 Gbit/s)
• Housing material: aluminium and plastic
• Cable length: 0.15 m
• Ports quantity total: 4 (3 USB + 1 RJ-45)

How to use

Connect the integrated USB Type-A plug to a compatible host port or use the included Type-C adapter for a USB Type-C host. After plugging in, the hub typically installs automatically using the host operating system's built-in drivers; no additional software is required for standard USB and Ethernet functionality. Attach USB peripherals to the Type-A downstream ports and connect an Ethernet cable to the RJ-45 port to obtain wired network access. For best transfer performance, connect USB 3.0/3.2 devices and use a Gigabit Ethernet connection on the network side.

What to consider before purchase

• Short 0.15 m cable, intended for close-proximity use to the host device
• Not a powered hub — may not provide sufficient power for multiple high-draw bus-powered devices
• No video output or additional docking station features (display, audio return, etc.)

Recommendations

Use the GRAUGEAR G-HUB31L-A to add fast USB ports and a reliable wired LAN connection to laptops or desktops when you need compact, portable expansion. For large file transfers, connect USB 3.0/3.2 storage devices and ensure the host supports USB 3.2 Gen 1 to reach maximum throughput. If multiple high-power devices are required, consider using externally powered USB hubs or docking stations.
