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.
