The UGREEN USB-C to Micro B Cable M/M 1M Black – US312 is a specialized high-performance data and charging solution designed to bridge the gap between modern USB-C hardware and legacy Micro-USB 3.0 peripherals. Whether you are a creative professional offloading footage from a DSLR or a student accessing archived projects on an older portable drive, this cable provides a stable, high-speed link without the need for cumbersome adapters.
SuperSpeed Data Transfer & Syncing
Equipped with USB 3.1 Gen 1 technology (often referred to as USB 3.0), the US312 is engineered for efficiency. It supports a theoretical maximum data transfer rate of 5Gbps.
Rapid File Moving
In practical terms, this allows you to transfer a 1GB video file in just a few seconds.
Storage Support
It is fully optimized for high-capacity external hard drives, comfortably supporting devices up to 4TB (including popular models from WD My Passport, Seagate Expansion, and Toshiba Canvio).
Backward Compatibility
While it excels at high speeds, it remains fully compatible with USB 2.0 (480Mbps) and USB 1.1 devices, ensuring it works with virtually any Micro-B equipped hardware.
Charging and Power Delivery
Beyond data, the US312 is a robust power delivery tool. It supports a charging output of up to 5V/3A (15W).
Stable Power
This ensures that power-hungry external HDDs receive sufficient current to spin up and maintain a stable connection during long backup sessions.
Device Charging
It is also suitable for charging older smartphones (like the Samsung Galaxy S5 or Note 3), tablets, and cameras that utilize the Micro-B 3.0 port.
Premium Build and Durability
UGREEN is known for “over-engineering” its cables for longevity, and the US312 is no exception. It features a sophisticated internal architecture to protect signal integrity.
Triple-Layer Shielding
The UGREEN USB-C to Micro B Cable M/M 1M Black – US312 utilizes foil, braid, and ground shielding to minimize EMI/RFI interference, which is critical for preventing data corruption during high-speed transfers.
Reinforced Construction
The exterior is wrapped in a flexible, high-grade PVC jacket tested to withstand over 10,000 bend cycles.
Corrosion Resistance
The connectors are nickel-plated to resist oxidation and ensure a secure, “click-in” fit every time.
This US312 cable is a “plug-and-play” essential for users of modern MacBook Pros, Dell XPS laptops, or iPad Pros who still rely on dependable, older-generation storage and photography gear.
