Promaster Professional USB 3.0 Multi Card Reader

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 and Cine type 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.
