USB Rotary Splitter Hub with 4 Port USB 3.0/2.0 Expansion and Hot-Swap Functionality

This compact USB rotary splitter hub provides a practical solution for expanding USB connectivity on computers, laptops, and workstations. With four individual USB ports arranged in a rotary configuration, it transforms a single USB socket into multiple connection points for peripherals, storage devices, and accessories. The hub supports hot-swapping functionality, allowing you to safely connect and disconnect USB devices without powering down your system or restarting applications. Constructed from durable ABS plastic with precise engineering, this hub delivers reliable data transfer while maintaining a small footprint on your desk or workspace. Its plug-and-play operation eliminates complex installation procedures, working immediately with most modern operating systems to provide additional USB connectivity exactly when you need it.

Technical Specifications and Performance

The USB rotary hub incorporates technical features designed for consistent performance across various computing environments and peripheral requirements.

USB Standards Compatibility

This hub supports the Hi-Speed USB 3.0 and 2.0 interface standards with backward compatibility extending to USB 1.0 specifications. The theoretical maximum transfer speed reaches up to 5GB, accommodating both high-speed data transfer needs and legacy device connections. This compatibility ensures the hub works with a wide range of USB devices including U disks, card readers, USB mice and keyboards, scanners, digital cameras, USB sound cards, and hard disk enclosures. The hub utilises a second-generation USB HUB controller chipset that manages data flow efficiently between connected devices and the host computer.

Power Distribution and Protection

Each of the four USB ports provides individual power supply capability up to 300mA, sufficient for operating multiple USB-powered devices simultaneously. The hub operates with a 5V working voltage and 500mA working current, drawing power directly from the host computer's USB port without requiring an external power adapter. Integrated current protection functions safeguard connected devices against overload voltage conditions and instantaneous current spikes, enhancing operational safety. This protection system helps prevent damage to both the hub itself and any connected peripherals during irregular power conditions or connection issues.

Environmental Operating Range

The hub maintains stable operation across a specified environmental range, functioning in temperatures from -20°C to 75°C with operating humidity between 10% and 90%. Storage conditions extend from -40°C to 85°C, allowing for safe transportation and storage when not in use. These specifications ensure reliable performance in typical office, home, and light industrial environments where temperature and humidity might fluctuate. The hub's construction using first-class electronic components contributes to this environmental resilience and operational stability over extended use periods.

Physical Design and Connectivity

The hub's physical design focuses on practicality, accessibility, and space efficiency for various installation scenarios and usage patterns.

Rotary Configuration and Port Access

The rotary design positions four USB ports around a central axis, allowing you to rotate the hub to access each port conveniently without repositioning the entire unit. This configuration proves particularly useful in confined spaces or when connecting multiple cables with different orientations. The rotation mechanism provides flexible access to all ports while maintaining a compact overall footprint. Each port supports the hot-swap function, enabling you to connect or disconnect devices while the system remains operational—particularly valuable for data transfer tasks, peripheral sharing, or device testing scenarios.

Compact Dimensions and Housing

Measuring 15.5cm in length, 7.8cm in width, and 2.7cm in height, the hub occupies minimal desk space while providing substantial connectivity expansion. The ABS plastic housing offers structural rigidity and protection for internal electronic components, with a classic design featuring an exquisite shell finish. Available in both black and white colour options, the hub can match various computer setups, office environments, or personal preferences. The compact size makes it equally suitable for desktop computers, laptop workstations, media centres, or portable setups where space conservation matters.

Connection Scenarios and Device Support

This hub supports connection scenarios ranging from simple peripheral expansion to complex multi-device setups. It accommodates up to 127 USB devices through daisy-chaining or multiple connections, though practical limits depend on power requirements and specific device compatibility. Common supported devices include USB flash drives, external card readers for memory cards, input devices like mice and keyboards, imaging equipment such as scanners and digital cameras, audio interfaces including USB sound cards, and storage solutions like external hard disk enclosures. The hub's design particularly suits users who regularly transfer data between multiple storage devices or work with several USB peripherals simultaneously.

Installation and System Compatibility

The hub requires minimal setup and works with a broad range of operating systems, making it accessible for both home and professional users.

Plug-and-Play Operation

For most modern operating systems, this hub functions as a true plug-and-play device requiring no additional driver installation. Simply connect the hub to an available USB port on your computer, and the system should recognise it immediately, allowing you to begin connecting peripherals right away. This immediate functionality applies to Windows 2000, 2003, ME, XP, and Vista systems, as well as Mac OS 8.1 and higher versions. The only exception involves Windows 95 and 98 systems, which require specific driver installation—a consideration for users maintaining legacy computer systems.

Operating System Support Range

The hub maintains compatibility across multiple generations of operating systems, supporting both Windows and Mac platforms. This broad compatibility ensures the hub remains useful even as you upgrade computers or switch between different systems. The specified supported systems include Windows 95, 98, 2000, 2003, ME, XP, Vista, and Mac OS 8.1 or higher versions. This extensive support range makes the hub suitable for diverse computing environments, from modern home offices with current operating systems to specialised workplaces maintaining older systems for specific applications or compatibility requirements.

Practical Application Scenarios

In practical terms, this USB hub addresses common connectivity challenges in various settings. Home users benefit from additional ports for charging devices, connecting cameras, or using multiple input devices simultaneously. Office environments utilise the hub for connecting printers, scanners, external drives, and security devices to shared workstations. Creative professionals working with digital cameras, audio interfaces, and storage arrays appreciate the hot-swap capability for efficient workflow management. Educational settings find the hub useful for computer labs or presentation stations requiring multiple device connections. In all scenarios, the hub's compact design and rotational port arrangement provide flexible, accessible USB expansion without consuming excessive desk space.
