The Targus Universal Docking Station w/ Digital Audio is designed to connect to any notebook with a USB port. Simply plug in the USB cable to connect a network, keyboard, mouse, printer, speakers or other external peripherals. The digital audio connection transforms your DVDs or music into virtual surround sound for an in-home theater experience. Other unique features include two high-power USB ports providing twice as much power as a standard USB port, which allows you to connect USB devices with higher power requirements. In addition, these two ports have the Targus exclusive “Always On” technology which keeps the ports powered, even if the notebook is shut down or disconnected, so you can continuously charge your digital devices.
