The universal docking station that links all your electronic devices to your laptop with just one single USB 3.0 cable. This will allow you to use access to large screen displays, stereo speakers, external hard drive, optical drive, printer, full-size keyboard, mouse (etc.) using only one cable connected to your laptop which is often useful if your laptop doesn't have many usb ports.
It comes with cable to connect your laptop with and the power lead. I don't really use it anymore so I am selling it.
