Compare to traditional laptops, the modern day ultra-thin laptops with USB3.1 Type-C™ (such as MacBook, Chromebook Pixel, DELL, etc.) have very few ports (maybe 1 or 2). The number of ports often create problems for people on the move that may want to charge them phone, transfer data and connect other devices. This is where PQI's USB-C 3-Port Multi Hub shines. The 3-port hub offers a USB3.1 port, USB Type-C™ port and a HDMI port. The two USB ports allows for charging devices (Type-C™) or data transfer (USB3.1) while the HDMI port offers 4K resolution with compatible display devices.
