How to use

Insert an SD or microSD card into the appropriate slot until it clicks into place. Choose the connector that matches your host device (USB 3.0 Type-A for many computers, Micro USB or USB-C for mobile devices and modern laptops) and plug the reader into the host port. The host device should recognize the card as external storage; open the file manager to browse, copy or move files. After transferring data, use the host’s eject or safe removal procedure before disconnecting the reader to avoid data corruption.

Usage recommendations

For best performance, connect via the USB 3.0 Type-A port when transferring large photo or video files from high-speed cards. When using mobile devices, ensure the device supports OTG/host mode and use the appropriate connector. Regularly back up important files to another storage location and avoid removing the card during active read/write operations.
