How to use

Insert a compatible SD card (SD UHS-II, UHS-I, or non-UHS) into the reader’s card slot, then connect the reversible USB-C connector to a USB-C port on your computer. The device uses plug-and-play functionality; the operating system should recognize the card as removable storage so you can copy, move, or edit files using your usual file manager or editing software. Eject the card via the OS before removing to prevent data loss.

Recommendations

For best performance, use UHS-II SD cards when transferring large RAW images or high-bitrate video to approach the reader’s maximum transfer rates. Keep the connector and card slot free of debris and insert cards fully to ensure a reliable connection.
