Logitech Wireless Solar Powered Keyboard

The Logitech Wireless Solar Keyboard K750 is a solar powered keyboard that powers itself whenever there’s light, even indoors. It charges through its integrated solar panel — no power bricks or charging cables needed and it stays charged for at least three months in total darkness. It also features a solar power app lux meter to help you get the necessary light, making it easy to get at-a-glance information about battery levels. It even alerts you when you need more power.
