This hub is small and light enough to carry around with your laptop and mouse. Not a single port wasted. USB-C power adapter to hub, then hub to USB-C port to charge laptop. microSD, HDMI, additional USB ports. Remember that 4k only works up to 30Hz. The mouse pointer moves like a rabbit when you move it. No problem when travelling. At home, use the DP port on the laptop. It doesn't heat up either, just slightly.
