UGREEN Revodok CM880 (55544) 8-in-1 USB-C Docking Station
The UGREEN Revodok CM880 (55544) is an 8-in-1 USB-C docking station designed to expand the connectivity of compatible laptops and computers. It combines 4K@60Hz HDMI output, three high-speed USB 3.2 data ports, Gigabit Ethernet, a 3.5mm audio connection, a dedicated USB-A audio bridge interface and 100W USB-C Power Delivery input. Its multifunctional design supports external displays, wired networking, USB accessories, audio devices and laptop charging through a single USB-C host connection.
8-in-1 USB-C Expansion for Work and Entertainment
The UGREEN CM880 (55544) provides eight integrated interfaces for building a more versatile desktop setup. These include one HDMI output, two USB-A 3.2 ports, one USB-C 3.2 data port, one RJ45 Ethernet port, one 3.5mm audio jack, one dedicated USB-A 2.0 audio bridge port and one USB-C PD input. This combination is useful for connecting an external monitor, portable storage, wired network and audio equipment while keeping a compatible laptop powered. The dedicated audio bridge interface provides an additional specialized connection rather than functioning as a regular USB peripheral port.
4K@60Hz HDMI Output for High-Resolution Displays
The HDMI 2.0 output supports resolutions up to 3840 x 2160 at 60Hz with compatible equipment. This makes the docking station suitable for connecting an external monitor, television or projector for office work, presentations, video playback and everyday multimedia use. The 60Hz refresh rate provides smoother movement than 30Hz at the same resolution. Achieving the maximum display mode requires a USB-C host with compatible video-output capability, a suitable HDMI cable and a display supporting the selected resolution and refresh rate. Display mirroring and extension depend on the connected computer and operating system.
10Gbps USB 3.2 Ports for High-Speed Data Transfer
The UGREEN CM880 features two USB-A 3.2 ports and one USB-C 3.2 data port, each supporting theoretical transfer speeds up to 10Gbps with compatible devices. These interfaces are useful for connecting portable SSDs, USB flash drives and other high-speed storage accessories. The additional USB-C data port accommodates modern USB-C peripherals, while the USB-A ports provide convenient connections for conventional accessories. Actual transfer performance depends on the host computer, connected devices, cables and shared USB bandwidth. The dedicated USB-A 2.0 audio bridge interface is intended for its specialized audio function rather than ordinary USB storage expansion.
Gigabit Ethernet for Reliable Wired Networking
The built-in RJ45 Ethernet port supports 10/100/1000Mbps network connections, allowing compatible laptops to connect to routers, network switches and office LAN infrastructure. Wired networking is useful for online meetings, accessing shared files, downloading content and maintaining a consistent local network connection. It also provides a practical Ethernet solution for slim laptops without a built-in RJ45 socket. Actual network performance depends on the Ethernet cable, connected network equipment and available internet or local network bandwidth.
Integrated Audio Connectivity and Dedicated Audio Bridge
The UGREEN CM880 (55544) includes a 3.5mm combined audio jack for compatible headphones and headsets, making it convenient for calls, multimedia playback and desktop audio setups. A separate USB-A 2.0 audio bridge interface supports the docking station's specialized audio connection function with another computer when used with the appropriate connection arrangement. This feature distinguishes the CM880 (55544) from conventional USB-C hubs focused only on display, data and charging. The audio bridge port should not be treated as a standard general-purpose USB-A data port.
100W Power Delivery and Durable Aluminum Design
The UGREEN CM880 provides a dedicated USB-C Power Delivery input supporting up to 100W from a suitable USB-C PD charger. Compatible laptops can receive charging power while using the docking station's display, USB and networking functions. Actual power delivered to the host may be lower than the input rating because the dock consumes operating power, and charging depends on the connected charger, cable and computer. The aluminum housing offers a practical construction for everyday desktop use, while the compact design makes the docking station suitable for office workstations, home computing and portable setups. Users should verify their host device's USB-C video, data and charging capabilities before purchasing.
