USB hub WENTRONIC Goobay 2in1 Slim 4-Port, USB 3.0 5 Gbit/s, model 79149

The WENTRONIC Goobay 2in1 Slim 4-Port USB hub (model 79149) is a compact USB 3.0 hub that expands a single USB connection into four downstream ports with up to 5 Gbit/s transfer speed. Designed for use with laptops and desktops, this slim hub supports high-speed data transfer for external drives, peripherals and accessories while maintaining a low-profile form factor that is convenient for travel and tidy workspaces.

Advantages

The hub provides four USB 3.0 ports that support up to 5 Gbit/s data throughput, enabling fast file transfers between a computer and external storage or other peripherals. Its slim and lightweight design makes it easy to carry and position on a desk without adding significant bulk. The plug-and-play functionality requires no additional drivers for most operating systems, allowing quick connection of mice, keyboards, flash drives, and other USB devices.

Suitable for

• Expanding USB connectivity on ultrabooks, laptops and small-form-factor desktops
• Connecting external SSDs, HDDs and USB flash drives for fast file transfers
• Attaching multiple peripherals such as keyboard, mouse, webcam and headset
• Use in travel and mobile work setups where a slim, lightweight hub is preferred

When it may not be suitable

This hub provides four standard downstream USB ports but does not include dedicated power delivery for charging high-current devices; using multiple power-hungry peripherals or charging large batteries simultaneously may result in limited charging current or reduced performance. It is not a replacement for hubs or docks offering video output, Ethernet or specialized features such as SD card readers.

Key specifications

• Interface: USB 3.0 (backwards compatible with USB 2.0/1.1)
• Number of downstream ports: 4
• Maximum data transfer rate: up to 5 Gbit/s
• Form factor: slim, compact and lightweight
• Connection type: single upstream USB cable (integrated or detachable depending on unit)
• Plug-and-play: driverless operation on most modern operating systems

How to use

Connect the hub to a host computer using the upstream USB connector, then plug your USB devices into the hub's downstream ports. For best transfer speeds, connect USB 3.0 compatible devices and use a USB 3.0 port on the host. If multiple devices are connected simultaneously, the available bandwidth is shared among them; for large external drives, transfer large files one at a time or use a direct host connection when maximum sustained throughput is required. Ensure the host computer supplies sufficient power when connecting several devices; if a device requires more current than the hub can provide, connect it directly to the host or use a powered hub.

What to consider before purchase

• Check whether your device has available USB 3.0 ports to achieve maximum transfer speeds
• Consider power requirements of connected peripherals — the hub may not provide charging current for high-power devices
• Verify if you need additional features such as video output, Ethernet or card readers that this hub does not offer
• Confirm the physical cable length and connector type suit your setup if the upstream cable is fixed

Usage recommendations

Use the WENTRONIC Goobay 2in1 Slim 4-Port USB hub for expanding everyday USB connectivity: attach input devices and external storage for general office tasks, file transfers and peripheral consolidation. For best performance, pair USB 3.0 devices with a host USB 3.0 port and avoid overloading the hub with multiple high-current devices simultaneously.
