UGREEN CM868 | SKU 55886
High-Speed Card Reading and Organized Storage in One Compact Device
The UGREEN CM868 USB-C Card Reader combines fast SD and microSD file access with a built-in memory-card storage case. It is designed for photographers, videographers, content creators and travellers who need to import, copy, back up and organize memory-card files without carrying a separate card case.
Three active reader slots support two full-size SD cards and one microSD/TF card. Two cards can be accessed together in supported combinations, while the magnetic storage compartment separately holds two SD and two microSD cards when they are not in use.

SD 3.0 Performance up to 170MB/s
With a compatible high-speed memory card, USB-C host and supported operating system, the card reader can achieve transfer speeds of up to approximately 170MB/s. This helps reduce waiting time when importing RAW photographs, high-resolution video, project files and camera backups.
Read Two Memory Cards Simultaneously
The reader can access two cards together, helping photographers and editors move files between cards or copy content from multiple sources without repeatedly disconnecting and reconnecting media.
| Combination | Supported Together |
|---|---|
| SD1 + SD2 | Yes |
| SD1 + microSD/TF | Yes |
| SD2 + microSD/TF | No—the SD2 and TF positions share operation |
Simultaneous transfer speed is shared across the connected cards and USB host connection.
