One USB-C port on your laptop. Three USB devices you want to run at once. Plus an SD card from the camera and a MicroSD from the phone. The CH255 handles all of it through a single cable. One SuperSpeed USB-A port hits 5Gbps for external drives; the other two run at 480Mbps for keyboards and mice. The built-in SD and MicroSD slots pull card data straight into your machine. Aluminium shell, 38 grams, integrated 10cm cable — it tucks into a bag pocket and stays there. Plug in, go. No drivers on Windows, macOS, or Chrome OS. Quick heads-up: the SD and MicroSD slots can't read at the same time, and this is for data, not charging
