Ugreen UG-20884 USB 3.0 A Male to Type C Male Cable Nickel Plating 2m
The Ugreen UG-20884 delivers USB 3.0 connectivity between legacy USB-A ports and modern USB-C devices through a durable 2-meter construction. This US184 model designation cable combines fast charging capabilities with high-speed data transfer in a single solution. The nickel-plated connectors and reinforced cable design provide reliable performance for daily device connectivity needs.
USB 3.0 Data Transfer Performance
The cable implements USB 3.0 protocol standards to achieve data transfer speeds up to 5Gbps. This bandwidth represents a tenfold improvement over USB 2.0 connections operating at 480Mbps. Large file transfers including HD video content, lossless audio archives, and high-resolution photography collections complete rapidly at these speeds.
Additionally, the UG-20884 maintains backward compatibility with USB 2.0 and USB 1.1 specifications. Older peripherals connect seamlessly through automatic protocol negotiation. The cable adapts transfer speeds based on the capabilities of connected devices without requiring manual configuration.
Fast Charging Architecture
The cable supports charging current up to 3A at 5V for USB-C devices. This 15W power delivery capacity accommodates smartphone, tablet, and peripheral charging requirements. The 2-meter length experiences current limitations at 2.4A maximum compared to shorter cable variants in the same product family.
Furthermore, the Ugreen UG-20884 supports multiple fast charging protocols including Quick Charge 3.0, Quick Charge 2.0, Huawei FCP, and Samsung AFC technologies. This multi-protocol compatibility ensures broad device support across different manufacturers’ charging standards. The cable does not support Huawei SuperCharge or OnePlus Dash Charge proprietary protocols.
Safety and Protection Features
The cable incorporates a built-in 56kΩ pull-up resistor for overcurrent protection. This component prevents excessive current flow that could damage connected device ports. The resistor configuration meets USB-C specification requirements for proper power negotiation between host and peripheral devices.
Moreover, the UG-20884 features an intelligent voltage management chip that automatically adjusts charging parameters. The chip monitors connected device specifications and adapts voltage delivery accordingly. This adaptive charging mechanism minimizes risks associated with incorrect voltage application during charging sessions.
Construction Materials and Durability
The cable utilizes tin-plated copper wire cores with 28/22AWG gauge specifications. The tin plating provides corrosion resistance for conductors while maintaining excellent electrical conductivity. This conductor material choice ensures reliable signal transmission across the cable’s 2-meter length.
In addition, the Ugreen UG-20884 employs multiple layers of internal shielding including aluminum foil protection. The aluminum shielding prevents electromagnetic interference from disrupting data transmissions. A ground wire further enhances signal stability by providing a reference path for electrical noise mitigation.
The cable features a PVC outer jacket with ABS reinforcement for enhanced durability. Molded strain relief structures at both connector junctions distribute mechanical stress away from vulnerable solder points. The reinforced design withstands over 10,000 insertion cycles based on manufacturer durability testing. Laboratory tests confirm the cable maintains performance through 5,000 bend cycles.
Connector Design and Reversibility
The cable features nickel-plated connectors on both USB-A and USB-C ends. The nickel plating resists wear and corrosion through repeated connection cycles. Plated contacts maintain consistent electrical connections over extended use periods.
Additionally, the USB-C connector provides reversible insertion capability. Users insert the connector in either orientation without checking alignment. This design feature eliminates frustration associated with traditional USB connector directional requirements. The reversible nature reduces physical stress on device ports from incorrect insertion attempts.
