Solar-powered products aren't a novelty. Implementing the technology, however, requires some thorough thinking to ensure some practical usage out of it. The Logitech K750 wireless solar keyboard is a fine example of putting this eco-friendly technology to good use.
Some might liken the K750's design to what we see on notebook keyboards, and the truth isn't far from that. With chiclet type keys spread across the surface, it does make it much easier to clean the keyboard from any potential dust buildup between your keys. While the keyboard looks absolutely thin, it is heavier than expected.
To give it an attractive sheen, the K750 comes with a glossy finish. In due time, you'll notice fingerprint smudges across this glossy layer. Though Logitech did make the effort to include a cleaning cloth with the K750, we'd rather not to have the glossy surface to begin with.
While the K750's top is predominantly black, a white border is spotted running at the edges. This white border spreads towards the underside of the K750, giving it a pure white bottom. Along the edges, we also spotted a small groove, where you can dig your nails in and extract the small, rechargeable battery that powers the K750.
As its name implies, the K750 comes with an array of solar cells at the top of the wireless keyboard, above the function keys. It is the only feasible place where these cells can get clear access to light sources. Thankfully, the K750 is able to absorb most light sources, including your usual indoor fluorescent lights. Some might be skeptical over the power of such artificial light sources, but a quick check with the Logitech solar app that measures the luminosity of the power source should convince them otherwise.
With a constant light source, we aren't worried for its battery stamina. On the solar app, the battery level never dipped below 90% with the K750 constantly exposed to a light source. In fact, when the K750 was left in the dark overnight, it retained the same battery level as we left it.
Not forgetting what the K750 really is, we took the opportunity to churn out this review using the K750. The typing experience may vary according to your habits, but for us, we were slightly thrown off course by the non-ergonomic layout of its keys. That, and the K750's two plastic kickstand that only managed to elevate it slightly, served to hinder our initial typing speed and accuracy.
Within a few hours of typing, we realized that the K750 does not give us the same comfort level we get out of more ergonomically designed keyboards. The keys were laid out flat and straight and they could strain your fingers over a prolonged period. There is however a semblance of customization with the aid of its function key used in tandem with the F1 to F12 keys.
Fortunately, we didn't have to press too hard on the keys to register an input, which contributed to how quiet each keystroke was. Given how thin its supporting legs were, a gentle touch would be preferred to prevent any unintended snapping of its legs.
In the long run, the promise of a keyboard that's perpetually charged by solar power should provide a considerable amount in cost savings, even at its asking price of S$129. With a three year local warranty tagged to the Logitech K750 wireless solar keyboard, we feel the price is still within acceptable means, if you are able to compromise on a slightly less comfortable keyboard to work with for eco-friendly reasons.
