Logitech K980 Solar Keyboard Review

We tested the Signature Slim Solar+ for several weeks and used it across a laptop, tablet, and a desktop to see how it handled daily typing and quick device switching. The keyboard’s slim, laptop-like key feel felt comfortable right away, and the solar charging strip kept it powered during normal home-office lighting without any recharge fuss.

Typing stayed quiet and consistent, and the build felt solid—especially the recycled-plastic parts that give it a reassuring weight. The customizable Action Key added useful shortcuts once we set them up through the companion app, though the customization process requires installing software on supported systems. Switching between three paired devices worked smoothly, but a few of our mobile devices required a quick re-pair when moving between operating systems.

Bottom Line

Overview of the Logitech Signature Slim Solar+ Wireless Bluetooth Keyboard

We found this slim solar keyboard easy to live with day to day. Typing felt familiar and laptop-like, and the low-profile keys made long sessions comfortable without the clack of a mechanical board.

The light strip really does keep it charged under normal indoor lighting, so we rarely worried about plugging anything in. Build quality felt solid and pleasantly minimal, though we missed backlighting for late-night work.

Switching between devices worked smoothly, and the programmable Action key saved us time once we set it up. Overall, it’s a durable, no-fuss full-size keyboard that leans toward practical rather than flashy.

Solar and Artificial Light Charging

We left this keyboard on a bright windowsill and under our desk lamp to see how the light charging holds up.
The solar strip reliably keeps the battery topped up during normal office lighting and sunny days, so we rarely worry about plugging it in.

What impressed us was the reserve power — after a week in low light it still typed fine, showing the stored charge lasts through brief dark spells.
On the downside, the charging needs steady light; very dim rooms force more reliance on stored energy and longer recovery times under weak bulbs.

Overall, the combo of solar and artificial-light charging made the keyboard nearly maintenance‑free for our daily use, as long as we remember to give it occasional exposure to decent light.

Long-Lasting Battery Performance

We used the keyboard for several weeks and the battery behavior impressed us. The solar charging kept the keyboard usable during our bright office days, and it held charge reliably through darker evenings without needing a plug-in top-up.

On low-light days we noticed slower recovery, so placement near a window mattered. The included internal battery felt dependable; we didn’t experience sudden shutdowns, only the expected gradual dimming of power indicators.

Charging convenience is a clear plus, but plan for occasional supplemental indoor lighting if your workspace is very dim. Overall, the battery system reduced interruptions and made the keyboard feel low-maintenance.

Customizable Action and AI Launch Keys

We found the programmable keys on the K980 intuitive and genuinely useful during daily work. Setting up shortcuts through the companion app took a few clicks, and assigning repetitive tasks to a single key saved real time on document edits and app switching.

The AI launch key felt handy for quick access, though its usefulness depended on the apps we already had configured—sometimes it opened tools we didn’t need. Customization is powerful but not foolproof; a small learning curve exists to avoid accidental triggers.

Overall, the action keys make routine workflows smoother once you invest a few minutes to map them to the apps and macros you actually use.

Multi-Device Connectivity

We jumped between a laptop, tablet, and phone during testing and the keyboard switched smoothly with a single tap. Pairing over Bluetooth was straightforward, and the keyboard remembered multiple devices without re-pairing each time.

What we liked: switching felt instant and kept our workflow moving. It worked across Windows, macOS, iPadOS, iOS, and Android in our use, so we didn’t worry about compatibility when grabbing a different device.

What we didn’t love: switching can occasionally lag if a device’s Bluetooth was busy, so expect a second or two delay sometimes. Overall, the multi-device handling makes this keyboard a solid choice for people who use several gadgets daily.

Typing Experience and Build Quality

We spent a few weeks typing on this slim solar keyboard and found the feel very familiar — closer to a laptop deck than a mechanical board. Keys are low-profile and quiet, letting us type for long stretches without fatigue, though heavier typists might miss more pronounced tactile feedback.

The chassis feels solid and pleasantly weighty for its slim profile. The recycled-plastic construction and snug keycaps give confidence it’ll hold up, but the lack of backlighting can make late-night typing harder. Overall, comfortable and durable with a trade-off between slimness and tactile punch.

Eco-Friendly Materials

We noticed the keyboard feels solid and a bit weighty in a reassuring way, and that comes from noticeable recycled-plastic construction. The graphite model we tried uses a high share of reclaimed plastic in its shell, which reduces virgin material use without making the board feel cheap.

The light strip and battery system keep it cable-free long-term, and Logitech says the plastics meet a minimum recycled content threshold. That’s good for buyers who prioritize durability plus lower material waste, though the product still contains electronic components that aren’t recycled plastic.

In real use, the finish shows fewer fingerprints than cheaper keyboards, and the overall build suggests this is a device designed to last—supporting the environmental case for buying fewer replacements.

Quick Setup and Compatibility

We had the keyboard on our desk in minutes. Pairing over Bluetooth was straightforward — the device appeared in our system Bluetooth list and connected without extra drivers on Windows, macOS, iPadOS, iOS, Android, Chrome OS, and Linux.

The solar charging worked during typical office lighting, so we didn’t have to hunt for cables or a charger. Switching between devices with the dedicated keys was smooth, though we noticed a short lag when jumping between a tablet and a laptop sometimes.

Overall compatibility felt broad and reliable for mixed-device setups. If you rely on instant, cable-free switching across phones, tablets, and computers, this one fits well — just expect occasional brief reconnections when changing device types.

Pros and Cons

Pros

We found the Slim Solar+ reliable for daily typing. The solar charging kept it powered during regular office and home lighting, so we rarely worried about plugging anything in.

Typing felt familiar and quiet, with a low-profile, laptop-style key action that made long sessions comfortable. Build quality felt solid and slightly heavier than other slim boards, which gave it a reassuring stability on the desk.

Switching between devices via Bluetooth worked smoothly for us, and the customizable shortcuts in the Logi app saved time on repetitive tasks. Compatibility across Windows, macOS, iPadOS, and phones meant we could use one keyboard for multiple machines without fuss.

Cons

We noticed the keyboard lacks backlighting, which made typing in very dim environments harder than on backlit models. The low-profile keys may take a short adjustment period for users who prefer taller, more tactile switches.

Some of our team members felt keys register with minimal travel, causing occasional accidental presses until they adapted. Advanced users who expect mechanical feel or per-key lighting will likely find this design too basic.

Real User Impressions

We used the Slim for several weeks and liked how quietly it types and how slim it feels on the desk. The solar charging worked reliably under office lighting, so we rarely worried about battery life.

Typing felt fast and low-profile, though some of us bumped keys when moving our hands quickly; the light key travel takes a short adjustment. Pairing over Bluetooth was straightforward, and build quality felt solid for daily use.

The lack of backlighting stood out when working in dim rooms, and a few of us wanted slightly firmer key feedback. Overall, it’s comfortable for long sessions and dependable for everyday setups.

Space-Saving Home and Office Integration

We squeezed the slim keyboard into both our home desk and the office hot-desk without clutter. Its low profile and narrow footprint freed up room for a notebook and a compact mouse, so our workspace looked cleaner and felt less cramped.

Switching it between laptop, tablet, and phone was straightforward, which helped when we moved from a standing desk to a coffee-table setup. The lack of a charging cable eliminated another tangle, though the light strip needs a bit of exposure to keep the battery topped—put it completely under a desk lamp and you might see slower charging.

Overall, it fit into small work areas nicely and kept our shared spaces tidy, but plan for consistent light if you rely on its solar charging.

Conclusion

After using the Slim Solar+ for several weeks, we found it reliable and low-maintenance. Charging from room light eliminated battery anxiety, and the slim profile made typing comfortable for long sessions.

We liked the quiet, laptop-like keys and the solid build, though some of us missed backlighting and wished key sensitivity felt a touch more consistent. Overall, it’s a sensible choice if you want a neat, rechargeable Bluetooth keyboard that largely just works.
