K750 Wireless Solar KeyboardMake battery hassles a thing of the past with this wireless keyboard that is powered by indoor or natural light, plus can stay charged for up to three months. Light-check hot key clearly indicates if it's receiving enough light and ready to use. Long-range wireless connection virtually eliminates delays, dropouts and interference, so you can work and play in more places. Setup is as easy as plugging the wireless receiver into a USB port on your computer—no software required. Tiny Logitech® Unifying receiver is small enough to stay plugged in, reducing the chances of it getting lost. Concave keys feel good to the touch and make every keystroke comfortable, fluid and whisper-quiet. Wired/Wireless: Wireless; Maximum Wireless Range: 30 ft; Connector/Port/Interface: USB.
