About the UGREEN CM481 (30778)

The UGREEN CM481 (30778) is a powered USB 3.0 hub designed to expand one computer connection into seven USB-A ports. It helps users connect external drives, flash drives, keyboards, mice, printers and other compatible peripherals through a single hub, reducing the need to repeatedly unplug accessories.

Each USB-A port supports USB 3.0 data connectivity, with a maximum shared interface speed of 5Gbps. Individual on/off switches and LED indicators make it easy to manage connected devices, while the 12V/2A DC adapter provides external power for multi-device operation.

Four ports, numbered 4 to 7, support BC 1.2 charging. The gray aluminum-alloy construction and approximately 1-meter host cable make the CM481 suitable for home offices, desktop computers and workstations requiring additional USB connectivity.

Design & Performance

Seven USB-A 3.0 Ports for Multiple Devices

The CM481 provides seven USB-A 3.0 ports for connecting compatible flash drives, external storage, keyboards, mice, printers and other USB accessories. It helps keep several devices connected to a laptop or desktop through one hub.

The ports support standard USB data connectivity and are backward compatible with suitable USB 2.0 and USB 1.1 peripherals. This makes the hub useful for both newer storage devices and existing office accessories.

Up to 5Gbps USB 3.0 Data Transfer

USB 3.0 connectivity supports a maximum signaling speed of 5Gbps, providing bandwidth for file transfers and everyday peripheral use. Users can access compatible external drives and transfer documents, photos or videos without constantly changing connections.

The 5Gbps bandwidth is shared across the hub's connected devices. Actual transfer speeds depend on the computer, storage hardware and number of active peripherals.

Individual On/Off Switches with LED Indicators

Each of the seven USB-A ports has its own on/off switch and LED status indicator. Users can disable an unused port without physically unplugging the connected accessory, helping keep the workstation organized.

The independent controls are convenient for managing flash drives, printers and other USB peripherals. They provide a simple way to choose which devices remain active during daily work.

12V/2A External Power for Connected Peripherals

The CM481 uses a dedicated 12V/2A DC power adapter to supply additional power to connected USB devices. This is useful when several peripherals operate together, especially external storage and other accessories that may require more power than an unpowered hub can provide.

The external supply is rated at 24W in total, so available power is shared rather than independently supplied at full output to every port. The hub does not provide USB-C Power Delivery charging for a laptop.

BC 1.2 Charging on Four USB-A Ports

USB-A ports 4 through 7 support the USB Battery Charging 1.2 protocol, allowing compatible phones and USB-powered accessories to receive charging power through the hub. This adds practical charging functionality alongside ordinary USB data connectivity.

Charging performance depends on the connected device and the hub's available power budget. The CM481 is not a USB-C PD or high-wattage fast charger, and BC 1.2 support should not be confused with proprietary rapid-charging standards.

Aluminum Housing and Plug-and-Play Compatibility

The UGREEN CM481 features a gray aluminum-alloy housing with a compact desktop-friendly design and an approximately 1-meter host cable. Its metal exterior provides a sturdy enclosure for everyday use, while the separate power connection supports powered operation.

The hub supports standard plug-and-play USB functionality on compatible Windows, macOS and Linux systems. No dedicated driver is generally required for normal USB hub operation, making it convenient for home, office and technical workstations.

Who It's For

Office Professionals: Connect keyboards, mice, printers and USB storage. Desktop Users: Expand limited USB ports and keep accessories connected. Computer Technicians: Manage multiple USB devices with individual switches. Students: Access flash drives and other USB peripherals. Home Workstations: Add powered USB connectivity for everyday accessories.

The CM481 is best suited to users who need seven USB-A data ports with independent control and external power rather than HDMI, Ethernet or laptop Power Delivery charging.
