The Allegro Max 1-Port USB-C 3.2 Gen 2x2 PCIe Card adds one 20 Gb/s USB-C port to a computer running macOS 14.4+, Windows 10/11 or Linux Kernel 5.4+, or to a Thunderbolt expansion system such as Sonnet's Echo range. It draws bus power from the PCIe slot, delivers up to 15W (3A) to connected devices and supports charging, with a resettable overcurrent fuse and hot-swappable connection.
