Ugreen USB 3.0 to 4.0 USB 3.0 Hub (UG- 20805)

Ugreen USB 3.0 to 4.0 USB 3.0 Hub (UG-20805)

The UG-20805 transforms single USB 3.0 connectivity into four high-speed ports through compact hub design optimized for portability. This bus-powered hub maintains full 5Gbps data transfer speeds across all ports with intelligent bandwidth management. Moreover, the hub features ultra-slim construction and plug-and-play operation for seamless mobile computing integration.

High-Performance USB 3.0 Architecture

The UG-20805 incorporates advanced VIA VL813 hub controller that distributes USB 3.0 bandwidth efficiently across four downstream ports. Each port supports up to 5Gbps data transfer speeds with dynamic allocation based on connected device requirements. Additionally, the hub maintains backward compatibility with USB 2.0 and USB 1.1 devices while optimizing performance automatically.

The internal signal conditioning prevents crosstalk and maintains signal integrity across simultaneous multi-device operations. Furthermore, the UG-20805 includes error correction algorithms that ensure reliable data transmission during high-speed transfers.

Intelligent Power Management

The bus-powered design draws power directly from the host USB port without requiring external adapters. The UG-20805 delivers up to 900mA total current distributed intelligently across connected devices. Similarly, the hub includes smart charging detection that provides optimal power delivery for smartphones and tablets within USB specification limits.

The integrated power management prevents overcurrent conditions through automatic load balancing and device prioritization. Consequently, critical devices maintain power while lower-priority peripherals adjust consumption accordingly.

Ultra-Portable Form Factor

The hub measures just 3.9 x 1.2 x 0.6 inches with lightweight aluminum alloy construction weighing only 2.1 ounces. The UG-20805 includes integrated 6-inch USB 3.0 cable that eliminates the need for separate connection cables. Moreover, the slim profile fits easily in laptop bags and briefcases without adding bulk.

The rounded edge design prevents snagging on clothing and bag materials during transport. Therefore, the hub provides professional appearance suitable for business and academic environments.

Advanced Heat Dissipation

The aluminum alloy housing provides efficient thermal management during continuous operation with multiple high-speed devices. The UG-20805 maintains stable performance across temperature ranges from 0°C to 50°C without throttling. Additionally, the compact design includes strategic ventilation that prevents heat buildup in confined spaces.

The thermal characteristics enable reliable operation inside laptop bags and docking stations where airflow may be limited. Furthermore, the hub operates silently without cooling fans or moving parts.

Seamless Device Connectivity

The four USB 3.0 ports accommodate standard and high-speed peripherals including external storage drives, mice, keyboards, and mobile devices. The UG-20805 supports hot-plug operation for safe device connection and removal during system operation. Similarly, the hub maintains stable connections during laptop movement and transportation.

The precision-molded port housings provide secure device retention while allowing easy insertion and removal. Moreover, the ports include proper spacing that accommodates larger USB connectors without blocking adjacent ports.

Universal Compatibility Standards

The UG-20805 operates across Windows, macOS, and Linux systems with driver-free installation for immediate functionality. The hub supports both Intel and AMD platforms with consistent performance characteristics. Additionally, the device maintains compatibility with USB-C systems through standard USB-A to USB-C adapters.

The plug-and-play operation enables instant recognition by operating systems without configuration requirements. Furthermore, the UG-20805 includes comprehensive device support for printers, scanners, cameras, and storage devices.
