This memory card reader is made with an extremely durable aluminum housing and features that are worthy of the ProMaster Professional name. Accepts four types of memory cards: Compact Flash type 1, Secure Digital (including UHS-II), microSD, and Memory Stick.
Uses a fast USB 3.0 computer connection to ensure maximum speed.
CF slot is designed extra deep for a secure fit using type 1 cards.
SD slot can read and write at UHS-II speeds. This is a perfect match with ProMaster Velocity memory cards. Even if a UHS-II SD card is used in a non-UHSII camera it will still read at its top speed in this reader.
All 4 slots on the reader can be used simultaneously, which is a great way to read files, and write them between cards as well as a computer. Easy backups!
It is an unpowered hub right out of the box. Or by connecting a ProMaster AC adapter (3498) it becomes a powered hub to accommodate higher-drain USB devices. Includes two cords, one long USB-A and one short USB-C!
