My daughter uses her laptop to do her schoolwork on but it only has 2 USB ports which isn't enough to be able to connect her wireless mouse, a printer, USB drive for backing up her work to transfer to the school's computer, her camera and a cellphone. I bought this for her to use to avoid having to keep unplugging and plugging things back in to the laptop.
This hub is small and compact so it fits right into her laptop bag so she always has it with her wherever she goes. The hub has 4 USB ports and a cap that changes the hub from connecting with a standard USB plug to using a USB Type C plug to connect. The hub is plug and play so no need to download any drivers for this to work with the computer. The cable is about 6 inches long and the hub has a dimly lit ring of light on the bottom when it is plugged in.
