UGREEN CM401 USB-C Card Reader is a compact card reader that provides fast data transfer over a USB-C connection. The device supports a wide range of memory cards, accepts capacities up to 2 TB and works without additional drivers via plug-and-play. Its small dimensions make it convenient to carry in a laptop bag or backpack.

Advantages

The CM401 delivers high transfer speeds up to 5 Gb/s and supports simultaneous reading and writing on two cards, which helps save time when moving large files. USB 3.1 compatibility ensures significantly faster transfers than USB 2.0. The included USB Type-C connector allows connection to modern laptops, smartphones and tablets, while the compact portable design avoids blocking adjacent ports.

How to use

Recommendations

Use high-quality SD or Micro SD cards that match the reader's supported formats and do not exceed 2 TB capacity. When transferring large amounts of data, ensure the host device uses USB 3.1 to achieve the maximum 5 Gb/s speed, and avoid removing cards during active read/write operations.
