USB hub Green Cell HUB-GC-C4A — 4-portový USB-C 3.0 hub

Green Cell HUB-GC-C4A is a compact 4-port USB hub that converts a single USB-C port into four USB 3.0 Type-A ports. Designed for users who need extra connectors on laptops, tablets or desktop computers, the hub supports the higher transfer speeds associated with USB 3.0 and enables simultaneous connection of storage drives, input devices and other peripherals in a small, portable housing.

Advantages

The hub offers four full-size USB 3.0 ports in a lightweight, space-saving enclosure, delivering faster data transfers than legacy USB 2.0 connections. Its USB-C plug provides a simple, reversible connection to modern hosts while maintaining backward compatibility with USB 3.0 devices. The compact design and low power consumption make it convenient for travel and daily use without requiring additional drivers on most operating systems.

Suitable for

• Connecting external flash drives and portable hard drives for file transfer and backup
• Expanding USB connectivity for keyboards, mice and other input devices on laptops and tablets
• Attaching USB accessories such as card readers, webcams or dongles
• Temporary workstation setups where multiple USB-A ports are needed

Key specifications

• Interface: USB-C plug to four USB 3.0 Type-A ports
• Data transfer rate: up to USB 3.0 speeds (SuperSpeed, up to 5 Gbps per port, subject to host/device limits)
• Power: bus-powered from host USB-C port (no dedicated external power adapter)
• Compatibility: works with devices that support USB-C host mode; backward compatible with USB 3.0/2.0/1.1 peripherals
• Form factor: compact, lightweight hub designed for portability

How to use

Plug the hub's USB-C connector into the host device's USB-C port. Connect USB-A peripherals into any of the four available ports. For large external drives or multiple high-current devices, check the host's available power output; some high-power devices may require a dedicated powered hub. Most operating systems will recognize connected devices automatically; if a device requires specific drivers, install them according to the peripheral manufacturer's instructions.

Recommendations

Use the hub for expanding basic USB connectivity and data transfer tasks. Avoid connecting multiple high-power-draw devices simultaneously if the host provides limited current. For continuous operation with several external hard drives or bus-powered devices that require higher current, consider a hub with external power to ensure stable performance.
