ProMaster Trifecta USB C & USB A UHS-I SD & MicroSD Card Reader

The ProMaster Trifecta UHS-I Card Reader is a compact, go-anywhere reader for transferring photos and video from SD and microSD memory cards. Its big trick is right in the name: three built-in connection options let you plug into USB-C, USB-A, or Micro-USB devices without keeping track of a pile of adapters and dongles.

For photographers bouncing between a camera, laptop, desktop, tablet, or mobile workflow, it's a particularly handy little thing to leave in the camera bag. The reader supports both full-size SD and microSD cards, and both slots can be accessed simultaneously as independent drives. That means you can transfer files from either card to your computer or even copy files between cards.

Three Ways to Connect

The Trifecta incorporates USB-C, USB-A, and Micro-USB connections into its compact body. This makes it considerably more versatile than a reader built around a single connector, particularly if you're working with a mix of newer USB-C equipment and older computers or devices that still rely on USB-A or Micro-USB.

SD + MicroSD Support

Dedicated slots accept both full-size SD and microSD memory cards, including SDHC and SDXC formats. Both slots can be used simultaneously, making the reader useful for downloading multiple cards or creating quick card-to-card copies.

UHS-I Performance

The Trifecta is designed for UHS-I memory cards with transfer speeds of up to 90MB/s. It's a great match for everyday photography cards, including U1, U3, V10, and V30 media.

UHS-II SD cards can be used with UHS-I readers through the standard's backward compatibility, but they will operate at UHS-I speeds rather than taking advantage of their full UHS-II performance. For photographers regularly using high-speed UHS-II cards, ProMaster's Trifecta Deluxe UHS-II reader is the better choice.
