StarTech HB30C3A1GE USB-C Hub with 3-Port USB-A and Gigabit Ethernet

Overview

The StarTech HB30C3A1GE is a compact, AC-powered USB-C hub that converts a single USB Type-C port into three USB 3.2 Gen 1 Type-A ports running at up to 5 Gbps each, plus a dedicated Gigabit Ethernet (RJ-45) port supporting 10/100/1000 Mbps networks. For field technicians, IT administrators, and mobile integrators who need wired connectivity and peripheral expansion without hunting for an open wall outlet, this hub covers both requirements from a single laptop port. The 300mm attached cable keeps the hub close to the machine and off the edge of a desk.

Key Features

• Three USB 3.2 Gen 1 Type-A Ports at 5 Gbps: Each port delivers full USB 3.2 Gen 1 bandwidth — fast enough to transfer a 10GB video archive in roughly 20 seconds. Plug in a USB storage drive, IP camera configuration tool, and a barcode scanner simultaneously without slowing any device to USB 2.0 speeds.
• Gigabit Ethernet (RJ-45) with Auto-MDIX: The integrated RJ-45 port negotiates 10/100/1000 Mbps automatically and supports Auto-MDIX, so straight-through or crossover cables both work without manual configuration. This matters on job sites where the available patch cable is whatever happens to be run to the closet.
• IEEE 802.3az Energy-Efficient Ethernet: When the connected network link is idle, the port reduces power consumption automatically — relevant on battery-powered laptops where every milliwatt of draw counts during a long commissioning session.
• Full-Duplex Flow Control per IEEE 802.3x: Simultaneous send and receive at line rate without packet loss during large file transfers, which makes a practical difference when uploading firmware to multiple NVRs or pulling camera footage for review.
• 802.1q and 802.1p VLAN and QoS Support: The Ethernet port passes VLAN-tagged traffic and honors QoS priority markings — useful when connecting to a managed network where cameras, VoIP, and data are segmented across VLANs. No need to de-tag at the hub.
• AC Adapter Included, 5V/2A Output: The included 100–240V AC adapter ensures all three USB-A ports deliver full bus power regardless of the host laptop's USB-C power delivery capacity. Laptops vary widely in how much downstream power they can source; the adapter eliminates that variable entirely.
• 10W Maximum Power Consumption: The entire hub — three USB ports loaded plus active Gigabit Ethernet — draws no more than 10W at the wall. That is well within the capacity of a standard outlet strip on a server rack or AV cart.
• 300mm Attached Cable: The 30cm pigtail keeps the hub stable on a flat surface next to a laptop rather than hanging off the edge of the port under torque. On a crowded workbench this reduces connector stress on the host machine's USB-C receptacle.
• 0°C to 50°C Operating Range: Covers normal indoor commercial environments from a cold warehouse loading dock in winter (once ambient rises above freezing) through a warm server closet in summer. Not rated for outdoor exposure or industrial temperature extremes.
• Compact Plastic Housing, 50g: At 87mm × 45mm × 14mm and 50 grams, the HB30C3A1GE fits in a laptop bag side pocket. Field technicians who carry their own tools will not notice the weight addition.

Integration and Compatibility

The HB30C3A1GE connects via USB 3.2 Gen 1 Type-C and is backward-compatible with USB 3.0 and USB 2.0 host ports using an appropriate adapter, though maximum data throughput is capped at the host port's actual standard. The Ethernet port presents as a standard USB-to-Ethernet adapter to the host OS, supported natively by Windows, macOS, and most Linux distributions without third-party driver installation. The hub is compatible with StarTech's broader USB connectivity lineup and fits naturally alongside USB hubs and docking stations used in enterprise IT deployment kits. For integrators managing network infrastructure during commissioning, pairing this hub with a managed network switch on the same bench allows simultaneous wired network access and peripheral device connection from a single laptop. Those planning cable runs should also review a structured cabling planning guide to ensure the RJ-45 drop at the commissioning workstation is correctly terminated for Gigabit speeds. If you are deploying camera systems that require laptop-side configuration tools alongside USB capture devices, check the IP camera installation accessories category for complementary field tools.

Frequently Asked Questions

Q: Does the HB30C3A1GE require a driver installation on Windows or macOS?

A: The hub uses standard USB Audio/HID class and USB-to-Ethernet adapter drivers built into modern operating systems. Windows 10/11 and current macOS versions recognize both the USB hub and Gigabit Ethernet port without third-party software installation.

Q: Do all three USB-A ports deliver full 5 Gbps simultaneously, or is bandwidth shared?

A: The hub interfaces to the host via USB 3.2 Gen 1, which provides a single 5 Gbps upstream channel. In practice, peak aggregate throughput across all three ports is bounded by that single upstream connection — if all three ports are saturated simultaneously, the effective per-port rate will be lower than 5 Gbps. For typical mixed use (one storage drive, one peripheral, one configuration tool), real-world performance is not meaningfully limited.

Q: What is the warranty on the HB30C3A1GE?

A: StarTech covers the HB30C3A1GE with a 2-year manufacturer warranty.

Q: Does the included AC adapter work internationally?

A: Yes. The included adapter accepts 100–240V AC input at 0.5A, covering North American, European, and most international mains voltages. A plug adapter for the local outlet type may be needed depending on the country.

Q: Is the Gigabit Ethernet port compatible with VLAN-tagged networks?

A: Yes. The HB30C3A1GE Ethernet port supports IEEE 802.1q VLAN tagging and IEEE 802.1p QoS priority, so it passes tagged frames transparently to the host — useful on segmented enterprise networks where cameras, management traffic, and data are on separate VLANs.

Q: Can the hub be used without the AC adapter plugged in?

A: The hub will function from bus power for basic data use, but USB downstream power delivery to connected devices may be limited or inconsistent without the AC adapter. For reliable operation of power-hungry peripherals on all three ports, connecting the AC adapter is recommended.

Ted Perry

The HB30C3A1GE fills a specific gap I see repeatedly on camera and access control commissioning jobs: a laptop with a single USB-C port, a need for wired Gigabit Ethernet to reach the management VLAN, and at least two USB peripherals to connect at the same time. The included 5V/2A AC adapter is the detail that makes this practical — you are not gambling on whether the host laptop's USB-C port will supply enough power to keep a USB storage drive and a Gigabit Ethernet adapter both happy simultaneously.

Technical Highlights:

• 5 Gbps USB 3.2 Gen 1 per port: Fast enough to pull a multi-gigabyte NVR configuration backup or firmware package in seconds rather than minutes — meaningful when you are working through a 20-camera site in a single day.
• 802.1q/802.1p Ethernet compliance: The RJ-45 port passes VLAN tags natively, so you can plug directly into a managed switch trunk port and reach the camera management VLAN without reconfiguring the switch for an untagged access port during commissioning.
• 100–240V AC adapter at 10W max draw: The entire loaded hub pulls under 10W at the wall — low enough that it will not trip the 15W USB-C power delivery budget on most business laptops even if you choose not to use the included adapter.

Deployment Considerations:

• The 300mm cable is long enough to reach a laptop sitting on a surface without pulling the hub sideways, but if you are connecting to a laptop mounted in a docking station with the USB-C port on the rear, measure before assuming the cable reaches comfortably to the desktop surface.
• Operating temperature is rated to 50°C — adequate for indoor work but not for a locked outdoor enclosure in summer sun; in those environments keep the hub inside a climate-controlled cabinet or inside the vehicle.

This is the right tool for a two-person commissioning crew running a single laptop between them on a camera installation where wired network access and USB peripheral connections need to be available at the same time without swapping cables — warehouses, data centers, and multi-floor commercial builds where the alternative is disconnecting and reconnecting adapters every time the job changes.
