If you enjoy tidy desks and the tiny existential relief of not worrying about tiny chargers and tiny batteries, Logitech’s latest is the kind of gadget that quietly simplifies life. The Signature Slim Solar+ K980 is a full-size wireless keyboard that tops its keys with a narrow light-collecting strip and then… refuses to need a cable. Logitech says the keyboard will keep itself topped up from any light source that reaches about 200 lux (think a dim daytime room), will run for up to four months in complete darkness once fully charged, and uses a rechargeable battery designed to last up to 10 years.

A tiny idea with a not-so-tiny promise

Solar keyboards aren’t new — Logitech itself has dabbled in this for years — but the K980 ambitiously leans all the way in: there’s no USB charging port on the retail model, and the “power management” behind the scenes (Logitech calls it Logi LightCharge) is built to keep you typing without thinking about charging. As Logitech put it in its launch materials, “Even the need to think about charging can be a distraction, so we designed Signature Slim Solar+ to take that off your plate completely.”

That ambition comes with a little realism: Logitech requires only 200 lux to trickle charge the keyboard (many indoor daytime scenarios meet that), but if you live in a literal cave, you’ll eventually need to bring it into light — or simply accept the four-month dark-use buffer once the battery is full. Those numbers are Logitech’s; reviews and hands-on impressions have generally found them plausible, but note that real-world results will depend on your desk lamp, office layout, and how often you actually leave the lights on.

What it actually is (and what it isn’t)

Physically, the K980 looks familiar to anyone who’s used Logitech’s slim office keyboards: low-profile scissor switches, full-size layout and a separate number pad, Easy-Switch keys to pair three devices, and Windows/macOS legends so it behaves across platforms. There’s also an Action key for assigning macros and a dedicated AI Launch key that defaults to Microsoft Copilot on Windows but can be reprogrammed — via Logitech’s Logi Options+ app — to call up other chatbots or shortcuts. The keyboard is made with a mix of recycled plastic and an aluminum inner plate and weighs in at a light enough to feel portable on a desktop.

But it isn’t a charging hub: the consumer model lacks a USB-C port, and there’s no wired fallback in the standard configuration. Logitech does offer business variants that ship with a Logi Bolt USB-C receiver for IT environments, and there’s a North America-market Mac layout too. Pricing landed at about $100 for the standard model and roughly $110 for the business / Mac variants.

The replaceable-battery twist

One obvious worry with a sealed, battery-reliant board is: what happens when the rechargeable battery dies? Logitech told reporters that the battery is user-replaceable and that spare parts will be available — iFixit will stock components — because the cell is encased in plastic rather than glued into a sealed unit. That’s a small but meaningful eco-win: if the keyboard can be repaired rather than trashed, it prevents a lot of e-waste down the line.

Beyond the headline: software and workflows

Logi Options+ is a bigger part of the package than you might expect. The app lets you remap the Action and AI keys, program “Smart Actions” that open app sets or workflows with a single press, and generally customize behavior across macOS and Windows. For people who like keyboard shortcuts to tidy repetitive tasks, that software is as meaningful as the solar tech itself. (Full disclosure: as with many proprietary utilities, some features live only inside Logitech’s software ecosystem.)

IT teams get some extra attention: the business SKUs can be monitored via Logitech Sync and deployed with Logi Bolt receivers for more secure, high-density setups — useful for offices trying to standardize devices without every desktop needing a charger or an IT ticket when an AA battery runs out.

So, should you buy one?

If your buying calculus includes: “I want less desk clutter, I use a keyboard in a lit room, and I don’t obsess over the exact feel of my keys,” then the Signature Slim Solar+ is an easy recommendation. It’s a small step toward everyday sustainability with a practical twist: you don’t have to remember to plug it in. If you’re a power typist who needs world-class keycraft, or you work in truly low-light conditions, consider a different Logitech or a mechanical option and keep a cable handy.
