Ugreen USB-C to 7-Port USB-A 3.0 Hub CM481 Product Overview
The Ugreen USB-C to 7-Port USB-A 3.0 Hub DC 12V EU CM481 is a professional-grade powered expansion station built to transform a single USB-C port into a high-capacity workstation hub. This high-performance adapter bridges the gap between modern Type-C devices and standard USB-A peripherals, allowing you to connect keyboards, mice, flash drives, and external storage setups simultaneously. Equipped with a dedicated mains power supply, it prevents the voltage drops and device disconnections that frequently limit traditional bus-powered splitters.
Core Features and Technical Specifications
Multi-Port SuperSpeed Data Transfer
The Ugreen hub features seven downstream USB-A 3.0 interfaces utilizing an advanced data processing core. This architecture supports SuperSpeed data transfer rates up to 5Gbps per port, allowing uncompressed media files, massive system backups, and database directories to transfer smoothly. It maintains complete backward compatibility with legacy USB 2.0 and USB 1.1 hardware standards.
Dedicated 24W Power Delivery
To maintain continuous operation under heavy hardware loads, the hub includes an external DC 12V 2A power adapter featuring an EU standard plug wall connection. This dedicated electrical layout bypasses the power limitations of the host computer, ensuring that all seven ports deliver maximum data throughput and stable power output even when running multiple power-hungry external hard drives or solid-state drives simultaneously
Integrated Individual Switches and Status LEDs
Managing your active device links is exceptionally efficient with integrated individual control mechanisms. Each of the seven USB-A ports is equipped with its own dedicated physical on/off push button and a corresponding blue LED status indicator. This layout permits users to safely mount, unmount, or cut power to a specific peripheral device to protect delicate data pipelines without physically unplugging the cable.
Intelligent BC 1.2 Device Charging Protocols
Beyond raw data synchronization, four specific integrated ports are optimized with advanced Battery Charging 1.2 logic. The hub automatically detects connected smart accessories, smartphones, or small electronics to safely regulate and deliver optimal charging power up to 7.5W per optimized port. This multi-tier architecture prevents overcurrent, overheating, and short-circuits.
Key Benefits for Users
-
- True Hardware Expansion: Safely consolidates seven separate Type-A inputs into a single Type-C host interface to save desk space.
- Constant Link Stability: Independent 12V external power prevents random storage dismounts caused by system power fluctuations.
- Port Strain Protection: Individual physical switches minimize physical plug insertion cycles, saving delicate cable ends from long-term wear.
- Zero Driver Deployment: Full plug-and-play engineering functions instantly on Windows, macOS, Linux, and ChromeOS architectures without software installations.
