USB hub Green Cell HUB-GC-A4A — 4-portový USB-A 3.0 hub

Green Cell HUB-GC-A4A — 4-port USB-A 3.0 hub is a compact accessory designed to expand the USB connectivity of a desktop or laptop. The hub provides four USB-A 3.0 ports in a single housing, enabling simultaneous connection of flash drives, mice, keyboards, external hard drives and other peripherals. It supports plug-and-play operation and delivers USB 3.0 data transfer speeds while remaining compatible with USB 2.0 and USB 1.1 devices.

Advantages

The hub offers four high-speed USB-A 3.0 ports in a small footprint that fits into a workspace without adding bulk. Its plug-and-play design requires no additional drivers on standard operating systems, and backward compatibility ensures older devices remain usable. The device provides reliable wired connections for peripherals and supports standard power delivery within USB-A 3.0 specifications, making it suitable for both data transfer and charging low-power devices.

Suitable for

• Expanding USB connectivity on laptops with limited ports
• Connecting multiple peripherals at a desktop workstation
• Quick file transfer between flash drives and external drives
• Temporary charging of smartphones, accessories and low-power devices

Key specifications

• Interface: USB-A 3.0 (four ports)
• Data transfer: up to 5 Gbit/s per USB 3.0 specification
• Compatibility: backward compatible with USB 2.0 and USB 1.1 devices
• Power: bus-powered from host USB port (no external power adapter)
• Form factor: compact, lightweight hub housing with attached USB cable

How to use

Connect the hub to an available USB-A port on your computer using the attached cable. After connection, the operating system will recognize the hub automatically; no driver installation is typically required. Plug peripherals into any of the four USB-A 3.0 ports. For best data transfer performance, connect USB 3.0-compatible devices and use the hub on a host port that supports USB 3.0. Be mindful that total available power is shared between all connected devices when the hub is bus-powered.

Recommendations

Use the hub on a USB 3.0 port to achieve maximum transfer speeds and connect high-capacity storage devices one at a time if heavy power draw is expected. Avoid relying on the hub for charging multiple power-hungry devices simultaneously, as the bus-powered design limits available current per port.
