This was one impulse purchase I'm glad I made, as it totally changed the way desks are set up at work.

However, technical stuff aside, these are quality keyboards that everyone seems to like typing on, they are lightweight, and they don't waste any space. Regardless, paired with the M705 Marathon mouse, batteries are no worries, with some of our oldest mice at 4+ years on the original batteries. I haven't measured the output of the solar cells, so I'm not sure if they generate enough to support that. My only complaint would be the lack of a Caps Lock light. The solar app is helpful in determining charge level and whether or not the solar cells are receiving enough light (in an office environment with fluorescent and LED lighting, the lux gauge on nearly every keyboard is pegged at 500+, so the batteries are always at 100%). Thus they function and recharge the battery even when the keyboard is off. These cells do not require the keyboard to be on to function. The panel has solar cells which absorb light and convert it to electric power. Solar Logitech keyboards have solar panels at the top surface. The tea got in the contacts and shorted the Control key (computer thought it was being held down), but I got it cleaned out and that keyboard is still being used two years later. Short answer: Yes, the Logitech keyboards charges even when off. Another one took a tea spill to the left Control key, but I was able to successfully repair it. So far, only one has been retired due to worn out keys (cosmetic, keyboard still worked fine). Not only do I still have it and use it, we've deployed the K750 as standard equipment for the office and in the field at work (to date, well over 100 keyboards). I figured, like some other poor solar implementations I've seen, that this would need the occasional weekend in a window to recharge.īoy, I was wrong. Null Bought one on a whim several years ago.
