Description Ugreen UG-80856 6-in-2 usb-c multifunction adapter – cm380 The Ugreen CM380 (model UG-80856) transforms a single USB-C port into six essential connectivity options. This compact hub delivers simultaneous data transfer, display output, and power delivery through a unified aluminum housing. Comprehensive Port Configuration The adapter features a carefully balanced port selection for modern workflows. Two USB-A 3.0 ports provide 5Gbps data transfer speeds for legacy peripherals and storage devices. A dedicated USB-C port maintains the same 5Gbps bandwidth while supporting bidirectional connectivity. Additionally, the CM380 includes an HDMI port capable of 4K resolution output at 30Hz refresh rate. This display specification suits standard office applications and media consumption. The Ethernet port delivers 1000Mbps wired network connectivity with RJ45 compatibility. Power Delivery Integration The UG-80856 incorporates a USB-C Power Delivery port supporting up to 100W input. This pass-through charging maintains laptop battery levels during extended hub usage. The adapter reserves approximately 15W for its own operation, delivering up to 85W to connected devices. Power allocation works dynamically across ports. Users can charge devices while simultaneously transferring data and outputting video. The aluminum chassis provides effective heat dissipation during sustained operation. Display Output Capabilities The HDMI interface supports multiple resolution configurations. At 4K (3840×2160), the adapter outputs at 30Hz refresh rate. Lower resolutions enable higher refresh rates: 1080p operates at 60Hz for smoother motion rendering. Furthermore, the display output maintains backward compatibility with older HDMI standards. The connection supports HDCP content protection for streaming services. Signal integrity remains stable through the adapter’s internal chipset processing. Network Connectivity Performance The Gigabit Ethernet port provides 1000Mbps theoretical maximum throughput. Actual speeds depend on network infrastructure and cable quality. The RJ45 connection eliminates Wi-Fi interference concerns during bandwidth-intensive transfers. Moreover, the Ethernet adapter functions independently from USB data traffic. Users can achieve full network speeds while simultaneously accessing USB storage devices. The port supports auto-negotiation for 10/100/1000Mbps network speeds. Construction and Portability The Ugreen CM380 measures approximately 110mm in length with integrated cable design. The aluminum alloy housing provides structural rigidity while maintaining a 60-gram weight profile. This construction balances durability with portability requirements. The adapter uses a fixed USB-C cable rather than a detachable connection. This design choice reduces potential points of failure while maintaining flexibility during positioning. The cable length accommodates standard laptop placement configurations. Compatibility Specifications The UG-80856 operates with USB-C devices supporting DisplayPort Alt Mode for video output. Compatible operating systems include Windows 10/11, macOS 10.13 and later, Chrome OS, and various Linux distributions. The adapter functions as a plug-and-play device without driver requirements. However, video output requires host device support for DisplayPort over USB-C. Not all USB-C ports include this functionality. Users should verify their device specifications before purchasing for display purposes.
