How to use

Insert a compatible microSD card into the reader’s card slot, then plug the reader into a Type-A USB port on your computer. The operating system should recognize the reader as external storage; open the drive to copy, move or edit files. For best transfer speeds, use a UHS‑I microSD card that supports the higher read/write rates and connect to a USB 3.2 Gen 1 or USB 3.0 port.

Recommendations

To maximize performance, pair the reader with a high-performance UHS‑I microSD card (for example, the SanDisk Extreme PRO microSDXC UHS‑I series) and connect to a USB 3.2 Gen 1 or 3.0 Type-A port. Avoid removing the card during active transfers and store the reader in a protective compartment to prevent physical damage.
