Portable USB-C hub with Gigabit Ethernet and RS232

This compact hub adds two USB-A 5 Gbps ports, a Gigabit Ethernet jack and an FTDI-based RS232 serial adapter to laptops or desktops via USB 3.2 Gen 1 Type-C or Type-A. It includes an attached 2 ft host cable and a USB-C to USB-A dongle for broad host compatibility. The unit draws up to 15 W for its own operation and reserves the rest of the 100 W Power Delivery 3.0 budget for host charging.

100 W Power Delivery 3.0 pass-through

An external USB-C power adapter (not included) connects to the hub’s PD input to deliver up to 85 W to the host while the hub itself consumes 15 W. This reserved overhead prevents the device dropouts or power overdraw that can occur with hubs lacking dedicated power management. The feature is decisive for users who need continuous charging during long data or serial sessions.

Attached USB-C to USB-A dongle and 2 ft host cable

The integrated dongle lets the hub work with legacy USB-A hosts without a separate adapter, while the fixed 2 ft cable reduces cable clutter and loss risk. FTDI chipset on the RS232 port ensures reliable serial communication for industrial, networking or legacy equipment. Gigabit Ethernet supports WoL, Jumbo Frames and VLAN tagging per IEEE 802.3 standards.

Questions about this item

What does the 640 MB/s network media data transfer rate mean when I connect this hub to my laptop?

That figure represents the theoretical maximum throughput of the Gigabit Ethernet link; real-world file transfers will be lower due to protocol overhead and system limits.

How does the USB 3.2 Gen 1 uplink cap the Gigabit Ethernet and serial ports in practice?

The 5 Gbps host link shares bandwidth between the two USB-A ports, the Gigabit Ethernet controller and the FTDI serial adapter, so simultaneous heavy traffic on all ports can saturate the uplink.

What does the hub need physically to mount or sit securely on my desk?

The unit is a compact dongle with a 2 ft attached USB-C cable and an integrated USB-C to USB-A adapter; it requires no mounting hardware and sits inline with the host connection.
