StarTech 5G4AC-USB-C-HUB 4-Port USB-C to USB-A Hub, 5Gbps Bus Powered

Overview

The StarTech 5G4AC-USB-C-HUB is a slim, bus-powered USB-C hub that expands a single USB-C port into four USB-A connections — each running at USB 3.2 Gen 1 speeds up to 5Gbps. At 2.9 oz and just 0.6 in thick, it sits flat on a desk or drops into a laptop bag without adding meaningful weight. The 11.8 in (30 cm) attached cable keeps things tidy without restricting placement, and the 16.5 in (420 mm) hub body spreads four Type-A ports far enough apart to avoid blocking adjacent connectors with wider USB adapters. No driver installation, no external power brick — connect it and it works across USB hubs and connectivity accessories in almost any operating environment.

Key Features

• 4x USB 3.2 Gen 1 Type-A Ports at 5Gbps: Each of the four downstream ports delivers up to 5Gbps throughput — roughly ten times the ceiling of USB 2.0. Transferring a 10GB surveillance archive or a large firmware update package takes seconds rather than minutes. All four ports are independent, so saturating one does not throttle the others down to USB 2.0 speeds.
• USB-C Host Connection (5Gbps, 24-pin): The upstream connector is a full USB 3.2 Gen 1 Type-C plug, compatible with any host that exposes a USB-C SuperSpeed port. This covers virtually every current laptop, workstation, and single-board computer used in security and AV deployments today without needing a separate adapter.
• Bus Powered — No External Supply Required: Power draws entirely from the host USB-C port, eliminating a dedicated power brick and a second outlet at the workstation. For mobile deployments or temporary staging setups, this matters — one cable connects everything.
• USB-C Auxiliary Power Port: A dedicated USB Type-C auxiliary power input lets you supplement bus power when connected peripherals demand more current than the host can supply. Connecting a USB-C charger here stabilizes operation when all four ports are loaded with power-hungry peripherals simultaneously.
• USB 3.2 Gen 1 Backward Compatibility: The hub is fully backward compatible with USB 2.0 and USB 1.1 devices — older peripherals like card readers, legacy security dongles, or serial adapters with USB 2.0 connectors connect and function normally, just at their native speed ceiling rather than being blocked.
• Broad OS Compatibility: Verified across Windows, macOS, Linux, ChromeOS, iPadOS, and Android. Security operations centers, control rooms, and field technicians running mixed-OS environments do not need to validate OS support per machine — it works across the board.
• Operating Range 0°C to 70°C (32°F to 158°F): The rated operating temperature covers standard indoor environments including server rooms, control desks, and equipment racks that run warm. Storage is rated down to -10°C (14°F), so units shipped or stored in unheated warehouses during winter months are not at risk of damage before deployment.
• Space Gray Plastic Housing: The matte space gray finish blends into most professional workstation setups and does not show fingerprints as readily as gloss alternatives. The plastic construction keeps weight at 2.9 oz — a metal housing of equivalent size would add meaningful carry weight for field technicians.
• Non-Condensing Humidity Rating (10%–85% RH): Suitable for typical indoor environments including air-conditioned control rooms and standard office spaces. Not rated for outdoor or high-humidity installations — plan accordingly if the deployment environment involves condensation risk.

Integration and Compatibility

The 5G4AC-USB-C-HUB (often searched as 5G4AC USB C HUB) connects to any host with a USB 3.2 Gen 1 or USB 3.1/3.0 Type-C port — laptops, NUC-style edge compute devices, workstations, and ARM-based single-board computers used in access control and automation systems. It works with USB peripherals and accessories across all six supported operating systems without additional drivers. For deployments where a laptop serves as a temporary VMS client or configuration terminal, this hub adds the USB-A ports that thin-and-light laptops increasingly omit. Pair it with a docking and peripheral setup for a more complete desk configuration. The auxiliary USB-C power port means you can supplement host power from a standard USB-C PD charger when running four high-draw devices simultaneously — useful in staging environments where you are provisioning multiple USB storage devices or security keys at once. For larger port requirements or PoE-driven network infrastructure, see the managed and unmanaged network switch category. Review the USB connectivity buying guide if you are evaluating whether USB 3.2 Gen 1 bandwidth is sufficient for your specific peripheral mix.

Frequently Asked Questions

Q: Does the 5G4AC-USB-C-HUB require a separate power adapter to operate?

A: No. It is bus powered and draws power directly from the host USB-C port. However, a USB Type-C auxiliary power port is included — connecting an external USB-C charger to that port is recommended when all four downstream USB-A ports are simultaneously loaded with power-hungry peripherals.

Q: What operating systems are compatible with the 5G4AC-USB-C-HUB?

A: The hub is compatible with Windows, macOS, Linux, ChromeOS, iPadOS, and Android. No drivers are required for standard operation on any of these platforms.

Q: Can I use USB 2.0 or USB 1.1 devices with this hub?

A: Yes. The hub is backward compatible with USB 2.0 and USB 1.1 devices. Those devices will operate at their native speed — up to 480Mbps for USB 2.0 — not at the hub's 5Gbps maximum.

Q: What is the warranty on the 5G4AC-USB-C-HUB?

A: StarTech provides a 2-year manufacturer warranty on the 5G4AC-USB-C-HUB.

Q: What are the physical dimensions of the hub, and how long is the attached cable?

A: The hub body measures 16.5 in (420 mm) long, 2.1 in (54 mm) wide, and 0.6 in (16 mm) tall. The attached USB-C host cable is 11.8 in (30 cm) long. Total weight is 2.9 oz (82 g).

Q: Is the 5G4AC-USB-C-HUB suitable for outdoor or high-humidity environments?

A: No. The hub is rated for indoor use with operating temperatures of 0°C to 70°C (32°F to 158°F) and non-condensing humidity between 10% and 85% RH. It is not rated for outdoor installation or environments where condensation may occur.

The 5G4AC-USB-C-HUB resolves a specific problem that comes up constantly in security and AV deployments: the laptop or edge device sitting at a workstation has one USB-C port, and the technician needs to connect USB storage, a security dongle, a card programmer, and a legacy peripheral simultaneously. The hub's 16.5 in elongated body keeps all four USB-A ports accessible without crowding, and the 11.8 in cable gives just enough reach to position the hub flat on the desk while the laptop sits behind a monitor arm.

Technical Highlights:

• 5Gbps per-port throughput: At USB 3.2 Gen 1 speeds, transferring a 64GB microSD card image — common when staging edge recorders or mobile units — takes roughly two minutes rather than the fifteen-plus you would wait on a USB 2.0 port. Each port is independent at 5Gbps.
• Auxiliary USB-C power input: When all four ports are loaded — for example, four USB drives running simultaneously during a batch firmware staging operation — supplementing via the auxiliary USB-C port prevents the bus from browning out. This is the feature that separates this hub from simpler bus-only designs in high-load scenarios.
• 0°C to 70°C operating range: Covers standard equipment rooms and control desks that can reach 60°C+ in summer without air conditioning. Storage down to -10°C means units stored in unheated receiving areas over winter ship and deploy without temperature-related failure risk.

Deployment Considerations:

• Bus power works fine for mice, keyboards, low-draw card readers, and USB dongles. Connecting a 2.5-inch spinning hard drive or multiple bus-powered drives to all four ports simultaneously will likely exceed the host's available current — use the auxiliary USB-C power port in those cases.
• The 10%–85% non-condensing humidity rating is an indoor-only spec. Do not install this hub in enclosures that see temperature swings large enough to cause condensation — even brief exposure can cause corrosion on the PCB connectors over time.

This hub is best positioned for security systems integrators who provision laptops as temporary VMS configuration terminals or staging stations — environments where USB-A expansion on a modern thin-and-light machine is the limiting factor, and where the auxiliary power port provides the headroom to run multiple USB storage devices at once without a dedicated powered hub.
