Of course, buying into the Unifying line basically limits you to the Logitech brand, but the company consistently earns our favor across its entire line of peripherals, including 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. That's standard battery technology, but 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. The panels power the integrated ML2032 lithium manganese button-cell rechargeable battery that then pushes power to the keyboard. The standout features on the K750 are obviously the dual solar panels that sit on either side of the logo branding on top of the keys. This type of keyswitch also allows Logitech to reduce the thickness of the keyboard chassis to just one-third of an inch. 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. But if Logitech produces an ergonomic keyboard with this solar technology inside, we might be persuaded to take the plunge.With its low-profile keycaps and a glossy black mirrored finish behind them, the K750 solar keyboard looks more like a disconnected laptop keyboard than its desktop counterparts. But there' not the abundance of shortcuts found on some keyboards, so the K750 shouldn't look out of place on a professional's desk.Īnd anyone worried about data leakage from the wireless connection can take heart from the 128-bit AES encryption that's automatically invoked whenever the keyboard is in use.Īt £70 the price is perhaps a bit steep. The Function keys have some embedded actions to control music playback, adjust volume and perform a few other shortcut actions, and there's a separate number pad and cursor keys. If you get the latter response the keyboard starts drawing on its reserve power. Smiley face and green light means yes sad face and red light means no. There is a button on the upper right of the keyboard, and pressing it lets you know if there's enough sunlight to power the keyboard without it needing to call on its reserves.
The slightly indented keys (Logitech calls the design Incurve) makes the keys feel comfy under the fingers and there is a nice clicking sound when keys are pressed. The rest of the build is a lot more solid than those feet, we're pleased to say. There are two rather plasticky feet you can use to raise it at an angle if you prefer this to having the keyboard sit flat on the desk.
The keyboard uses one of the Logitech unifying wireless dongles that will allow up to six mice and keyboards to be attached - handy if you work from a notebook and move between locations where you use different mice and keyboards. Which makes it just as well that Logitech says the K750 can keep going for at least three months in total darkness. Now admittedly we do sit near a window - but even so, there are rarely shafts of super-bright sunlight streaming through. There are two long solar panels sitting at the top of the keyboard, and we found that even in a home office with no lights switched on these gained enough power from ambient lighting to keep the keyboard alive and kicking through the entire period of our review. But in this case we think Logitech has got things right.

Solar powered kit is often not what it's cracked up to be. Logitech may have put an end to that particular barrier with its rather clever solar keyboard, the K750. If you are not really a fan of the need to keep batteries handy, then this alone could put you off going wireless. The thing about wireless mice and keyboards is that they have batteries, and these need recharging.
