USB Hubs

A USB hub is a hardware device that expands a single USB port into multiple ports, enabling several peripherals to be connected to a host system simultaneously. Also referred to as a USB splitter, USB port hub, or USB expander, these devices are essential where the native USB ports of a computer or workstation are insufficient for operational requirements. USB hubs support a broad range of connected devices, including keyboards, mice, storage drives, printers, and charging accessories.

RS Hong Kong stocks a comprehensive selection of USB hubs to meet professional and industrial demands. From compact bus-powered units to high-capacity powered USB hubs and multi-port USB-C hubs, our catalogue covers a wide range of configurations from trusted manufacturers.

Different Types of USB Hubs

USB hubs are classified according to two primary criteria: their power source, which determines how connected devices receive power, and their connector standard, which governs data transfer speeds and compatibility. Selecting the correct specification for each criterion is essential to ensure reliable performance across all connected peripherals.

• Bus-Powered USB Hubs: Bus-powered USB hubs draw power directly from the host device via the USB connection, requiring no external power supply. They are well-suited to low-power peripherals such as mice, keyboards, and USB flash drives, and are particularly convenient in portable or space-constrained environments.
• Self-Powered USB Hubs: Self-powered USB hubs, also referred to as powered USB hubs, utilise a dedicated external power adapter to supply consistent power to each port independently. This makes them the preferred choice for power-intensive peripherals such as external hard drives, optical drives, or USB charging hubs used to charge multiple mobile devices concurrently.
• USB-A Hubs: USB-A hubs feature the standard rectangular Type-A connector and are compatible with the vast majority of legacy and current USB peripherals. They remain the most widely deployed hub type across office and industrial environments.
• USB-C Hubs: USB-C hubs utilise the compact, reversible Type-C connector and are designed for use with modern laptops, tablets, and workstations that have transitioned away from traditional USB-A ports. A multi-port USB-C hub often integrates additional interfaces, such as HDMI connectors, SD card readers, and Ethernet ports, consolidating connectivity into a single, compact unit. These are especially relevant for laptop users working with current-generation hardware.

USB 2.0 Hubs

USB 2.0 hubs support data transfer rates of up to 480 Mbps and are appropriate for low-bandwidth peripherals including input devices, webcams, and printers. They represent a cost-effective solution where high-speed data throughput is not a primary requirement.

USB 3.0 / USB 3.1 Hubs

USB 3.0 hubs support transfer rates of up to 5 Gbps, while USB 3.1 hubs extend this to 10 Gbps. Both are suited to bandwidth-intensive applications involving external storage devices, high-resolution cameras, and data acquisition equipment, where transfer efficiency is critical to operational performance.

Applications of USB Hubs

USB hubs serve a critical function across a wide range of professional and industrial environments in Hong Kong, enabling scalable peripheral connectivity and streamlined device management wherever the native port capacity of a host system is a limiting factor.

Office Workstations & Hot-Desking Environments

In modern office environments, particularly those operating hot-desking or shared workstation models, a USB port hub enables employees to connect multiple peripherals, including monitors, keyboards, mice, and storage devices, through a single docking point. A powered USB hub or multi-port USB-C hub is commonly deployed here to support both data connectivity and device charging from a single centralised unit, reducing desk clutter and simplifying transitions between users.

IT Departments & System Administration

IT administrators routinely use USB hubs to connect multiple devices simultaneously during system provisioning, imaging, firmware updates, and diagnostics. A powered USB hub with sufficient port density allows technicians to manage several endpoints concurrently, improving workflow efficiency and reducing the time required for bulk device configuration.

Industrial Computing & Embedded Systems

In industrial computing applications, USB hubs are integrated into control panels, embedded systems, and machine interfaces to extend connectivity for barcode scanners, industrial cameras, data loggers, and HMI peripherals. In these environments, a self-powered unit is typically required to ensure stable, uninterrupted power delivery under continuous operating conditions. USB hubs used in such settings must meet the reliability demands of industrial-grade deployment.

Conference Rooms & Presentation Setups

Conference rooms and presentation environments frequently require simultaneous connection of laptops, display adapters, audio interfaces, and input devices. A multi-port USB-C hub or USB expander installed at the presentation point provides a standardised connection interface for visiting users, minimising setup time and ensuring compatibility across different host devices and operating systems.
