Turn one USB-C port into an extra HDMI, USB-C, and USB-A port with help of the HP USB-C to Multi Port Cable Converter. Connect this dock to your laptop and turn one port into 3 ports. The HDMI input will come in handy when you want to connect a monitor to your laptop. You can also use the USB-A port to connect a charging cable for your phone. The USB-C port ensures that your laptop's USB-C port doesn't become useless, as you can still use the USB-C input this way.
