Ugreen UG-15596 5 in 1 USB-C To HDMI + 3 USB 3.0 A + PD Power Converter

The UGREEN UG-15596 represents a comprehensive connectivity solution that transforms a single USB Type-C port into five functional interfaces: HDMI video output, three USB 3.0 Type-A ports, and USB-C Power Delivery charging. This adapter addresses peripheral expansion, display connectivity, and laptop charging requirements simultaneously through unified hardware.

Five-Port Integration Architecture

The UG-15596 integrates three independent subsystems within a single housing. The USB hub component manages peripheral connections across three ports, the HDMI adapter handles video signal processing, and the USB-C Power Delivery port enables laptop charging. All three subsystems operate concurrently without resource conflicts, allowing users to transfer data, extend displays, and charge their laptop simultaneously.

This convergence design eliminates the need for multiple separate adapters and preserves additional USB-C ports on the host device. Consequently, professionals need only one adapter instead of carrying separate USB hubs, HDMI adapters, and charging cables.

USB 3.0 Hub Performance

The three USB 3.0 ports implement USB 3.1 Gen 1 specifications, delivering theoretical bandwidth up to 5 Gbps. Each port supports practical transfer speeds approaching 500 MB/s when used individually. The shared 5 Gbps bandwidth distributes among active USB connections, meaning simultaneous transfers across multiple ports divide available throughput proportionally.

Furthermore, each USB port provides up to 900mA power output at 5V, adhering to USB 3.0 power delivery standards. This capacity accommodates most bus-powered peripherals including external hard drives, flash drives, keyboards, mice, webcams, and card readers without requiring supplemental power sources.

USB-C Power Delivery Passthrough

The USB-C PD port supports power delivery up to 100W (20V/5A), enabling laptop charging while the adapter remains in use. The Power Delivery protocol negotiates voltage and current automatically with compatible chargers:

• 20V/5A (100W) for high-performance laptops and workstations
• 20V/4.5A (90W) for Dell XPS and similar ultrabooks
• 20V/3.25A (65W) for MacBook Air and lightweight laptops
• 15V/3A (45W) for tablets and low-power devices
• 9V/3A (27W) and 5V/3A (15W) for smartphones and accessories

Moreover, the PD port incorporates intelligent power management that reserves approximately 15W for adapter operation and connected USB peripherals. Therefore, a 100W charger delivers approximately 85W to the laptop when the adapter and peripherals consume their allocated power.

HDMI Video Output Specifications

The HDMI port supports video output up to 4K resolution at 30Hz (3840 × 2160 pixels). This Ultra HD capability ensures compatibility with modern displays, monitors, and projectors. Additionally, the HDMI output supports lower resolutions at higher refresh rates:

• 1920 × 1080 pixels (1080p) at 60Hz for smooth full HD content
• 1680 × 1050, 1600 × 900, 1440 × 900 at 60Hz
• 1280 × 1024, 1024 × 768 at 60Hz for legacy displays

Moreover, the HDMI interface complies with HDMI 1.4 specifications, providing HDCP 1.4 content protection for encrypted video sources. The output automatically negotiates optimal resolution and refresh rate through EDID communication with connected displays.

DisplayPort Alternate Mode Implementation

The UGREEN UG-15596 utilizes DisplayPort Alternate Mode protocol available through USB Type-C connections. Therefore, the host device must support video output through its USB-C port—not all USB-C ports include this capability. Devices equipped with Thunderbolt 3, Thunderbolt 4, or USB-C with DP Alt Mode function properly with the UG-15596.

The adapter converts DisplayPort signals from the USB-C connection into HDMI output format. This conversion occurs through dedicated video processing chipsets within the adapter, maintaining signal quality and supporting various display modes.
