This isn't just an ordinary wireless keyboard. It is the world's first environmentally friendly wireless solar keyboard by Logitech. Powered by light and built from fully recyclable plastic, this super-slim keyboard that only measures at 1/3 of an inch boasts dual solar panels that sits on both side of the Logitech logo on top of the keys. It keeps the keyboard charged while you type without the hassle of battery replacement. With plug and play simplicity, just plug in the USB receiver and you can start typing.
Logitech puts in a lot of effort when it comes to the environment and no doubt about it when it comes to the K750. A great innovation in typing technology, the keyboard has a PVC-free chassis and even its packaging is made from recycled material. The dual solar panels on top of the keys power the integrated ML2032 lithium manganese button-cell rechargeable battery that then pushes power to the keyboard. The solar panels can also draw perpetual power from artificial light sources--in other words, you don't have to raise the keyboard to the sun for it to work; the fluorescent bulbs above you will charge it just fine. Logitech claims that a single 2-hour charge will retain power for three months in total darkness, or more if you remember to flip the on/off switch when you step away.
The K750 uses Logitech's PerfectStroke key design that adds exactly 3.2mm of space between each key and uniform tactile feedback across the entire concave key surface. In practice, the key response is similar to that of an IBM ThinkPad laptop, so if you're used to typing on a regular keyboard, the K750 will be an acquired taste. Your accuracy might suffer in the interim, but we actually found ourselves typing faster after less than a week of using it.
With USB ports quickly filling up with hardwired peripherals like speakers, mice, and Webcams, we're happy to see that the K750 integrates Logitech's 2.4GHz Unifying USB microreceiver. The Mini-USB plug sticks out less than an inch from any standard USB and can work in conjunction with up to six other Logitech input devices for up to 10 meters away from the source.
With an exception of an integrated palm rest and glossy black chassis that reveals fingerprints and scratches, overall this eco-friendly affordable keyboard will definitely help you to reduce energy consumption and save money by not investing in batteries. Unlike the mechanical keyboards currently popular in the peripheral market, this input device uses scissor switches underneath that register key presses with a lighter touch, and give the additional benefit of low noise and comfort.
