Logitech's latest keyboard is about as easy as you can get. It's wireless, universally compatible, and has no removable batteries or charging ports -- generating its own power through light.
The Signature Slim Solar+ is a full-sized keyboard that couldn't be easier to set up, and "just works" indefinitely after that, with no input from the user about battery levels. Sure, similar products already exist, like Logitech's K750 solar keyboard, but the Slim Solar+ lives up to its name as a sleeker -- and more affordable at $99 -- option with the home office in mind.

I installed the Slim Solar keyboard in my home office for a few weeks, and was sold on its ease of use, especially for swapping between my work and personal computers. But for those seeking a customizable keyboard, the Logi Options+ app make it as personalized as it is practical.
As its name implies, the Signature Slim Solar+ keyboard is light powered, but it doesn't need sunlight specifically. The keyboard absorbs ambient light through the strip along the top of the device, which powers it passively, generating the power it needs with the light available in your office or home.
This also means you don't need to stick the keyboard under a spotlight to generate enough power; "normal" lighting conditions work just fine, including the overhead fluorescents in the office. Unlike other solar keyboard models on the market, the strip is discreet and well-designed, adding little to its overall shape.

That doesn't mean it can't run out of juice, though. Logitech says that if it were used in total darkness, it would eventually die after about four months of not getting any light.
During a briefing, when pressed about the details of how much light is enough, a Logitech rep told me that you'd have to be using it extensively in very dim lighting for it to lose more power than it can generate. Ultimately, this means normal conditions are more than enough to keep the device powered, so it's one less thing to charge. Logitech says the solar battery will last up to 10 years, giving the keyboard a competitive lifetime for the $99 price point.

At 16 inches long and 1.5 pounds, it's available in black or white and otherwise a rather standard looking full-sized keyboard. The keys are designed to be universal, with labeling that works for not only just Windows and MacOS, but ChromeOS as well.
It follows suit with Logitech's MX line of keyboards with a utilitarian but well-designed aesthetic. Logitech advertises the Slim Solar+ as "laptop style" in that it doesn't have extensive key travel and features a flatter design, which of course, won't be for everyone. Although the board stays stationary and doesn't feel flimsy, it's still a much thinner and lighter frame than a heavier, more premium keyboard.

I've been using it with both my work laptop and personal PC, and it's comfortable to type on, with a satisfying, slightly textured finish and large keys. It also features a handful of extra "pebble keys" that extend all the way to the right, allowing you to swap connections with the "easy-switch" keys -- letting you use one keyboard for multiple computers.
The accompanying app, Logi Options+ lets users fully customize the function keys and remap to their preferences, but it's not required, as the Bluetooth connection makes it expressly plug and play.
The app highlights the customizable keys where you can set up your own actions, supporting some rather complex sequences like opening a new tab in the browser, and navigating to a specific website. This tutorial video, for example, shows how you can open Netflix with the press of a single button -- and this sequence is pre-loaded in the app as "Netflix Break." Cute.

Ultimately, though, the majority of users probably won't interact with the customization beyond a few different setups. The default mappings for each of the action keys (Calculator, Mute mic, Mute video, and computer lock) are probably some of the most useful, anyway.
There are three different versions of the Signature Slim Solar+ keyboard, the $99 universal multi-OS version, a MacOS-specific one (in white), and a $109 version for enterprise customers.
ZDNET's buying advice
Logitech excels at creating practical products that eschew flashy design elements for usability over time. The Signature Slim Solar+ keyboard is a perfect example of this, as you can't get more practical than a device that's wireless and doesn't require active charging.
At $99 for the standard universal version, I definitely recommend it for anyone who wants to use one keyboard for multiple computers and appreciates the sleek, wireless design.

The "laptop style" keyboard, however might feel a bit shallow for some users, and the overall design of the Slim Solar+ is a pretty standard affair. If you're looking for a mechanical keyboard with extensive key travel, Logitech's MX Mechanical is likely more up your alley.
