The UGREEN 20805 (Model CM473) is a high-performance connectivity expansion solution designed to add multiple high-speed ports to any host computer with a single USB-A connection. It includes an essential auxiliary power input for stable operation of high-draw peripherals.
Port Expansion: The device converts one host USB-A port into four independent USB 3.0 Type-A ports.
Data Standard: Complies with the USB 3.0 (USB 3.2 Gen 1) standard.
Transfer Rate: Supports a maximum data transfer speed of up to 5Gbps (SuperSpeed). This capability is critical for fast data synchronization and transfers with external storage devices.
Backward Compatibility: Fully compatible with legacy USB 2.0 and USB 1.1 standards.
Power Input: Features a dedicated USB-C port (DC 5V) for external power supply.
Purpose: This port is utilized to supply supplemental power to the hub. It is required when connecting power-intensive peripherals, such as multiple external hard disk drives (HDDs) or solid-state drives (SSDs), to ensure operational stability and prevent disconnections.
Limitation: The USB-C port is strictly for power input to the hub and does not facilitate host charging or data transfer.
