InLine 4in1 Gigabit Hub 33380S — USB-C/USB-A to 1×RJ45 + 3×USB 3.2 Gen 1

The InLine 4in1 Gigabit Hub 33380S connects a laptop or compatible device via USB-C or USB-A and provides a single Gigabit RJ45 Ethernet port plus three USB 3.2 Gen 1 ports. This compact adapter delivers a reliable wired network connection while expanding available USB connectivity for external drives, input devices and mobile device charging. The hub is suitable for users who need stable network performance and additional fast USB ports without carrying multiple adapters.

Advantages

The hub combines a full Gigabit Ethernet interface and three USB 3.2 Gen 1 ports in a small enclosure, enabling both wired networking and high-speed peripheral connections from a single host port. Its dual-role connector compatibility with USB-C and USB-A ensures wide device support. The USB 3.2 Gen 1 ports support transfer rates up to 5 Gbps for compatible devices, and the RJ45 Gigabit port provides stable, low-latency wired network access compared to typical wireless connections.

Suitable for

• Connecting a laptop without an Ethernet port to a wired LAN for faster, more reliable internet access
• Attaching external SSDs, flash drives or backup storage to a notebook or desktop
• Connecting USB peripherals such as keyboard, mouse or webcam while using a single USB-C/USB-A port
• Using in travel and temporary workstations where compact, multi-function connectivity is required

Key specifications

• Interface to host: USB-C and USB-A compatible connection (adapter/cable included or integrated as specified by vendor)
• Network port: 1 × RJ45 supporting Gigabit Ethernet (10/100/1000 Mbps)
• USB ports: 3 × USB 3.2 Gen 1 ports (up to 5 Gbps per port, backward compatible with USB 2.0/1.1)
• Form factor: compact, portable hub housing designed for desktop and travel use
• Power: bus-powered via host connection; charging capability depends on host power output and connected devices

How to use

Connect the hub to your computer using the USB-C or USB-A connector. Insert an Ethernet cable into the RJ45 port to establish a wired network connection; the operating system should detect the network interface automatically and configure it according to existing network settings. Plug USB devices into the USB 3.2 Gen 1 ports; storage devices will appear in the file manager and peripherals will be usable immediately once drivers are present or automatically installed by the host OS. Safely eject external storage before disconnecting the hub to prevent data loss.

Usage recommendations

For best network performance, use a Cat5e or higher Ethernet cable and connect to a Gigabit-capable switch or router. When using multiple high-power USB devices, verify the host port’s power output or use externally powered hubs if sustained charging or power-hungry devices are required. Keep firmware and system drivers updated to ensure compatibility and optimal transfer speeds.
