Ugreen UG- 15598 6 in 1 Multifunction Adapter USB-C To USB 3.0 A ( 3 port ) + 4K HDMI + RJ45 + PD

The Ugreen UG-15598 combines essential connectivity features in a balanced port configuration. This adapter emphasizes practical functionality through triple USB-A ports, display output, network connectivity, and power delivery in a unified device.

Triple USB-A Port Array

The UG-15598 features three USB-A 3.0 ports, each supporting 5Gbps theoretical data transfer speeds. This triple-port design accommodates multiple peripherals simultaneously without requiring additional hub devices. Users can connect keyboards, mice, external storage, and other USB accessories concurrently.

Furthermore, the three-port configuration reduces connection competition during multi-device workflows. Each port maintains USB 3.0 speeds when used individually. Simultaneous high-bandwidth operations across multiple ports may result in shared bandwidth allocation depending on total throughput demands.

4K Display Connectivity

The HDMI port delivers 4K resolution output for external monitor connections. The adapter supports 3840×2160 resolution at 30Hz refresh rate, suitable for productivity applications and content viewing. Lower resolutions enable higher refresh rates, with 1080p operating at 60Hz.

Moreover, the display output supports both mirror and extended desktop configurations. Users can duplicate their laptop screen for presentations or expand their workspace across multiple displays. The HDMI interface includes HDCP support for protected content playback from streaming services.

Gigabit Ethernet Performance

The RJ45 port provides 1000Mbps wired network connectivity with auto-negotiation capability. This Gigabit Ethernet implementation supports 10/100/1000Mbps network speeds depending on infrastructure capabilities. Wired connections eliminate wireless interference and provide stable bandwidth for data-intensive operations.

Additionally, the Ethernet adapter operates independently from USB data traffic. Network transfers maintain full speed while USB ports handle peripheral communications and storage access. The dedicated network controller prevents bandwidth conflicts during simultaneous operations.

Power Delivery Integration

The adapter incorporates a USB-C Power Delivery port for pass-through charging functionality. This port accepts power input while distributing connectivity features to other ports. The PD implementation maintains laptop battery levels during extended hub usage.

However, the specific power delivery capacity requires verification for individual use cases. The adapter passes through charging power while reserving operational overhead for hub functions. Compatible devices receive appropriate power based on USB-PD negotiation protocols.

Plug-and-Play Functionality

The UG-15598 operates without driver installation across major operating systems. Windows, macOS, Chrome OS, and Linux systems recognize the adapter immediately upon connection. This driver-free operation simplifies deployment across multiple devices and platforms.

Consequently, users can switch the adapter between different computers without configuration requirements. All ports function immediately after connection, subject to host device capabilities. Video output specifically requires USB-C ports with DisplayPort Alt Mode support.

Construction and Design

The adapter utilizes a compact housing with integrated USB-C cable design. This fixed-cable approach eliminates detachable cable connection points that can develop reliability issues. The housing combines materials optimized for durability and heat dissipation during operation.

The unit’s dimensions accommodate portable workspace requirements. The compact profile fits easily in laptop bags and travel cases. The lightweight construction adds minimal bulk to mobile computing setups.

Bandwidth Management

The adapter’s internal chipset manages data distribution across active ports. USB 3.0 ports share a common controller, allocating 5Gbps bandwidth among connected devices. Optimal performance occurs when high-bandwidth operations utilize ports strategically to minimize simultaneous heavy traffic.

Therefore, users transferring large files should consider spacing intensive operations temporally. Connecting multiple high-speed storage devices may result in reduced individual transfer rates when operating simultaneously. The Ethernet port maintains dedicated bandwidth separate from USB operations.

Host Device Requirements

Video output functionality requires USB-C ports supporting DisplayPort Alt Mode. Not all USB-C equipped devices include this capability, particularly older models or devices with USB-C charging-only ports. Users should verify their device specifications before relying on display features.

However, USB data ports and Ethernet connectivity function universally across USB-C equipped devices. Power Delivery operation requires host devices with PD charging support. Standard USB-C charging may not function through the adapter’s PD port depending on device compatibility.
