SanDisk micro SD to SD adapter 10749187

This SanDisk adapter lets you use a micro SD card in any device with a standard Secure Digital slot. It is built for photographers, drone pilots and anyone who needs to move files between phones, cameras and laptops. A write protection switch prevents accidental deletion. The compact size fits easily in a gear bag.

Suits users with mixed-format card slots

Ideal for owners of cameras, card readers or laptops that only accept full-size SD cards. Not suited for devices that require a micro SD card directly. Buyers who need USB connectivity or multiple card formats should look at a dedicated multi-card reader instead.

Write protection switch

The built-in slider locks the card against writes, protecting photos and video from accidental erasure. No software setup is required; just slide the switch before inserting the adapter. This single hardware feature decides whether the adapter meets your data-safety needs.
