The ProMaster Trifecta Deluxe Card Reader has three types of connections (USB-C, USB-A and USB Micro-B) along with iOS and Android OTG (on-the-go) compatibility for broad connectivity with your computer, tablet, and phone. Its dual slots accept SD and MicroSD cards, and the Trifecta can access them simultaneously as independent drives to allow for easy file transfer and copying. The reader works at UHS-II speeds of up to 300MB/s but is compatible with UHS-II cards. With all this functionality, the Trifecta is less than 3” long and weighs just under an ounce, so it’s easy to keep on hand for whenever you need it. With its sleek aluminum housing and protective caps made from aluminum and ABS plastic, the Trifecta provides portability and durability in equal measure.
