K750 Wireless Solar Keyboard, Black
It doesn't get more hassle-free than this. This solar-powered keyboard charges itself whenever there's light and stays charged for at least three months in total darkness--so you can say good-bye to batteries, power bricks and charging cables. With sleek lines and a thin profile, the streamlined design adds style to your workspace, whether you've got a laptop or desktop. Combining the best of traditional keyboards, laptops and a Logitech-only concave key cap design, you'll enjoy faster, quieter, feel-good typing hour after hour. Logitech Advanced 2.4 GHz wireless connectivity gives you the reliability of a cord plus wireless convenience and freedom-fast data transmission, virtually no delays or dropouts, and 128-bit AES encryption. The tiny Logitech Unifying receiver is small enough to stay in your laptop, so there's no need to unplug it when you move around. Plus, you can easily add compatible mice and keyboards without the hassle of multiple USB receivers. Wired/Wireless: Wireless
