Micro USB OTG Card Reader

This external card reader connects via a micro USB 2.0 interface and supports microSD, microSDHC and microSDXC cards up to 128GB capacity. It is designed for smartphones, tablets and other devices that provide USB on-the-go functionality. The compact form factor makes it easy to carry for mobile data transfer.

USB 2.0 interface limits

The reader operates over USB 2.0, so maximum transfer speeds are bounded by that standard rather than by the inserted card. Devices must support USB OTG and supply enough bus power for the reader and card to function. Cards larger than 128GB are not supported by this adapter.

128GB maximum card capacity

The single specification that determines suitability is the 128GB upper limit for microSDXC media. If your workflow requires reading or writing cards larger than 128GB, this reader will not meet that need.

Questions about this item

Should I pick a different capacity version of this card reader?

The reader itself has no built-in storage; it accepts microSD, microSDHC and microSDXC cards up to 128 GB, so you choose the card capacity you need.

What does the USB 2.0 label mean for actual transfer speeds?

The USB 2.0 interface sets the maximum data rate for the reader, so card read and write speeds cannot exceed that bus limit.

Does the USB 2.0 interface cap the maximum card size I can use?

No, the interface only limits transfer bandwidth; the reader supports microSDXC cards up to 128 GB regardless of the USB version.
