Ugreen UG- 50706 USB-C/USB-A Card Reader

Ugreen UG-50706, also designated as the CM185 model, represents a versatile dual-interface memory card reader engineered for professional content creators and mobile workflows. This compact device integrates both USB Type-C and USB Type-A connectors within a single aluminum alloy housing. The UG-50706 features two independent card slots that enable simultaneous reading and writing operations for SD and microSD formats. Built with USB 3.0 technology, this card reader delivers transfer speeds up to 5 Gbps, approximately 10 times faster than USB 2.0 standards.

Dual-Slot Simultaneous Operation

The Ugreen UG-50706 accommodates two memory cards concurrently through dedicated slots. The SD slot accepts full-size SD, SDHC, SDXC, MMC, and RS-MMC formats. Meanwhile, the TF (microSD) slot supports microSD, microSDHC, microSDXC, and UHS-I cards. Both slots operate independently when connected to computers or laptops, appearing as separate storage drives in file management systems. This parallel functionality eliminates repetitive card swapping during multi-camera shoots or drone operations.

Each slot supports individual card capacities up to 2TB. Consequently, the UG-50706 provides access to 4TB total storage when both slots contain maximum-capacity cards. The reader maintains full UHS-I speed class compatibility, ensuring optimal performance with modern high-speed memory cards.

USB 3.0 Transfer Performance

Built-in USB 3.0 chipsets enable the Ugreen UG-50706 to achieve theoretical maximum transfer rates of 5 Gbps (625 MB/s). Real-world performance allows 1 GB file transfers to complete in seconds rather than minutes. This bandwidth proves essential for 4K video workflows, where single recording sessions generate 100GB or more of footage. The UG-50706 reduces transfer time for such large files from approximately 30 minutes (USB 2.0) to under 3 minutes.

The device maintains backward compatibility with USB 2.0 ports. However, transfer speeds decrease to 480 Mbps when connected through legacy interfaces. For optimal performance, users should connect the UG-50706 to USB 3.0, USB 3.1, or Thunderbolt 3 ports.

Universal Connectivity Configuration

The Ugreen UG-50706 features two distinct connector types integrated into its 74mm length. The USB Type-A connector provides compatibility with traditional desktop computers, gaming consoles (PlayStation, Xbox), and smart TVs. Simultaneously, the USB Type-C connector enables direct connection to modern laptops, tablets, and smartphones.

This dual-interface design eliminates the need for separate adapters or dongles. Users can connect the UG-50706 to MacBook Pro models via USB-C, then immediately transfer data to legacy Windows PCs using the USB-A end. The device functions with both ports without requiring power cycling or reconnection.

OTG Mobile Device Support

On-The-Go (OTG) functionality allows the Ugreen UG-50706 to interface directly with Android smartphones and tablets. Compatible devices include models from Xiaomi (Mi 8, MIX 2), Huawei (P20 Pro, Mate 10), Samsung (Galaxy S9, Note 8), OnePlus (3T, 5, 6), and LG (G5, V20, V30). The card reader also supports iOS devices with USB-C ports, including iPhone 15 and iPhone 16 series, through the Files app integration.

OTG enables field professionals to offload footage directly to mobile devices without requiring a laptop intermediary. Photographers can review and backup images on tablets immediately after shooting. Drone operators can transfer aerial footage to smartphones for quick social media uploads or client previews.
