- Logitech K750 Wireless Solar-Powered Keyboard $39
Logitech K750 Wireless Solar Keyboard for $39 with free shipping.
Usually sells for around $49 and has good reviews.
Includes a little USB receiver for use on a desktop or laptop computer.
A little ambient light is all it needs to charge, and daytime light is usually enough to charge it for working all night.
It's not our favorite overall keyboard, but certainly one of the better wireless keyboards we have used, and never having to swap batteries is a nice bonus.
It is currently on backorder, with an expected ship date of 1-2 weeks.
