I've tried two of the 4-port models on a brand new MacBook Air and iPhone etc (using a USB-C to USB-A cable, not included contain). Not understood so far, it's the USB-C connector he doesn't like. The device works as advertised, but if you're plugging it into a USB-C port, you'll probably need something else. While this didn't work for me, it could work very well for your application and looks pretty slick. Apologies for the bad review, but I'm sorry I didn't see a review that made it clear not to use it with a USB-C port.
