Ugreen UG- 15600 9-in-1 USB-C Multifunction Adapter CM498 USB-C to USB 3.0 (3 Ports) + 4K HDMI + VGA + Gigabit Ethernet + SD & TF Card Reader

Versatile Docking Solution with Dual Video Outputs

The Ugreen UG-15600 (CM498) expands a single USB-C port into nine functional interfaces for comprehensive workspace connectivity. This multifunction adapter features three USB 3.0 ports, simultaneous 4K HDMI and VGA video outputs, Gigabit Ethernet networking, and dual memory card readers. Consequently, users gain complete peripheral connectivity while maintaining compatibility with both modern and legacy display systems through dual video output options.

Triple USB 3.0 Ports for Extended Peripheral Support

The UG-15600 incorporates three USB 3.0 Type-A ports delivering 5Gbps data transfer speeds each. These ports enable simultaneous connection of multiple peripherals including external hard drives, keyboards, mice, printers, and USB flash drives. Moreover, all three ports operate concurrently without bandwidth throttling when connected to devices with appropriate power requirements. The USB 3.0 specification ensures backward compatibility with USB 2.0 and USB 1.1 devices, preserving functionality for older peripherals.

Each USB port supplies 5V/0.9A power output, providing sufficient current for standard USB accessories. Therefore, users can connect bus-powered devices like portable hard drives, webcams, and USB microphones without requiring external power supplies. The ports maintain stable data transmission during simultaneous multi-device operation.

Dual Display Output Configuration

4K HDMI Video Output

The Ugreen CM498 features an HDMI port supporting 4K Ultra HD resolution at 30Hz refresh rate. This specification enables connection to modern monitors, televisions, and projectors with Ultra HD capabilities. Additionally, the HDMI output maintains backward compatibility with 1080p Full HD and 720p HD resolutions. The HDMI interface supports HDCP content protection protocols, ensuring compatibility with protected media content.

The HDMI connection delivers stable video signals for extended desktop configurations or screen mirroring. Users can leverage the 4K output for detailed graphic work, video editing, or presentations requiring high-resolution display fidelity.

VGA Legacy Display Support

The integrated VGA port provides analog video output supporting resolutions up to 1920×1080 at 60Hz. This legacy interface ensures compatibility with older projectors, monitors, and conference room display systems still utilizing VGA connections. Furthermore, the VGA port operates independently or simultaneously with the HDMI output, depending on the host device’s graphics capabilities.

The inclusion of VGA connectivity proves particularly valuable in corporate environments, educational institutions, and presentation venues where legacy display infrastructure remains prevalent. Users avoid carrying separate VGA adapters for compatibility with older equipment.

Display Mode Limitations

While the UG-15600 features both HDMI and VGA ports, simultaneous dual-display output depends on the host device’s USB-C port capabilities. Most USB-C laptops support single external display output through USB-C hubs. Therefore, users typically select either HDMI or VGA as the active video output. Devices with Thunderbolt 3 or Thunderbolt 4 ports may support dual simultaneous displays, subject to system specifications and graphics processing capabilities.

Gigabit Ethernet Network Connectivity

High-Speed Wired Networking

The Ugreen UG-15600 integrates an RJ45 Gigabit Ethernet port delivering network speeds up to 1000Mbps. This wired connection provides superior stability and lower latency compared to wireless networks. Additionally, the Ethernet adapter supports 10/100/1000Mbps auto-negotiation, ensuring compatibility with various network infrastructures and automatically adjusting to available network speeds.

The Ethernet chipset maintains consistent connection performance during bandwidth-intensive operations including large file transfers, video streaming, cloud backups, and video conferencing. Consequently, users experience fewer disconnections and more predictable network performance compared to Wi-Fi connections subject to interference and signal degradation.

Network Reliability Benefits

Wired networking through the CM498 eliminates common wireless connectivity issues including signal interference, range limitations, and connection drops. The Gigabit Ethernet connection proves essential for professionals requiring reliable network access for remote desktop sessions, VoIP communications, and real-time collaborative work platforms. Moreover, the stable connection supports consistent video conference quality without pixelation or audio lag caused by wireless signal fluctuations.

Dual Memory Card Reader System

The adapter includes separate SD and TF (microSD) card slots supporting simultaneous independent operation. Both slots support SDXC, SDHC, and standard SD formats with UHS-I specification compatibility. Transfer speeds reach up to 104MB/s per slot, facilitating rapid data imports from cameras, drones, action cameras, and mobile devices.

The dual-slot configuration enables concurrent data transfers from two memory cards without slot switching. Therefore, photographers and videographers can import footage from multiple cameras simultaneously, reducing workflow time. Each card reader operates independently, preventing data transfer bottlenecks when accessing both slots concurrently.

The SD slot accommodates full-size SD cards, while the TF slot accepts microSD cards without requiring adapters. This dual-format support ensures compatibility with diverse devices including professional cameras, smartphones, tablets, dash cameras, and drone systems.

Plug-and-Play Functionality

The Ugreen UG-15600 operates with driver-free plug-and-play functionality across major operating systems. The adapter requires no software installation for Windows 10/11, macOS 10.12 and later, ChromeOS, and Linux distributions. However, first-time Ethernet adapter recognition may require brief initialization periods on certain operating systems.

All functions activate automatically upon connection, including USB ports, video outputs, Ethernet connectivity, and card readers. The adapter draws power directly from the host device’s USB-C port, eliminating separate power adapter requirements for standard operation.
