128GB microSDXC Card with OTG Reader

This 128GB microSDXC card uses the UHS-I interface and carries a Class 10 speed rating. It delivers read speeds up to 70MB/s and write speeds up to 20Mb/s. The bundle includes a micro USB 2.0 OTG reader and a full-size SD adapter. It suits smartphone, tablet, and camera owners who need portable storage expansion.

Installing the card and using the OTG reader

Insert the microSDXC card into the supplied OTG reader, then plug the reader into a device with a micro USB port that supports USB On-The-Go. The card also fits directly into any microSDXC slot or into the full-size SD adapter for use in standard SD slots. A common issue is attempting OTG access on a phone that lacks OTG support, which prevents the reader from being recognised.

Checking your device before ordering

Verify that your phone, tablet, or camera accepts microSDXC cards up to 128GB and supports the UHS-I bus. Confirm the presence of a micro USB port with OTG capability if you plan to use the included reader. Devices limited to microSDHC will not address the full 128GB capacity.

Questions about this item
