This is perhaps the best keyboard if you’re looking for a wireless that never needs a battery replacement as it includes a solar panel that keeps the internal battery always charged by capturing the light from the sun or indoor light bulbs. It’s only 1/3-inch thick, which makes it ultra-thin adding a sleek style to your workspace and uses a 2.4 GHz wireless technology. The black version of the K750 solar keyboard works with Windows 10, and previous versions (no for Mac). All content on this site is provided with no warranties, express or implied.
