Official Star Wars R2-D2 4-Port USB Hub 4 USB 2.0 ports ports along the base of his chassis Chirps, squeals and beeps when you plug a new device into him Articulated legs allow R2 to stand up straight, or recline Powered by the USB bus, so a power supply isn't necessary for operation Some high-powered USB devices may need extra power, so R2 accepts a 7.5V external power supply (not included)
