AI Verdict
This is a 700g, 18mm thick, full-size Bluetooth keyboard with scissor-switch keys, powered by ambient light for up to 10 years, designed for multi-device users who hate charging cables.
This keyboard is a strong fit if your primary concern is never having to charge a keyboard via cable and you work in a well-lit environment. Its 18mm thick profile and 700g weight make it portable, and multi-device Bluetooth connectivity is a plus for switching between a laptop, tablet, and phone. However, the lack of backlighting and adjustable typing angle means it won't suit everyone's ergonomic or low-light needs.
If backlighting is crucial, look for keyboards with adjustable key illumination, even if it means sacrificing the solar charging feature.

- Connects to up to three devices via Bluetooth, with dedicated Easy-Switch buttons for quick toggling
- Offers a comfortable and responsive typing experience with low-profile scissor-switch keys
- Weighs 700g and measures 18mm thick, making it a slim and relatively light full-size keyboard

- Features a full-size layout with a numeric keypad and includes both Windows and Mac legends on the keys
Cons
- Lacks backlighting, making it difficult to use in dim environments

- The standard version does not include a Logi Bolt USB receiver, which is an additional purchase or only included in a more expensive business variant
- May struggle to charge sufficiently in very dim artificial light or when stored in dark places
- Constructed with a plastic casing, which feels less sturdy than metal keyboards like the MX series
Dimension Scores
The low-profile scissor-switch keys provide a comfortable and responsive typing experience, similar to a laptop.
User reviews consistently report rock-solid Bluetooth connectivity with no lag or disconnects across multiple devices.
The keyboard completely lacks backlighting, making it unsuitable for use in dim or dark environments.
Made from recycled plastic, it feels durable enough for daily office use and has a slim profile, but it's not as sturdy as keyboards with metal casings.
Best For
- desk setups where you want to eliminate charging cables for your keyboard
- users who frequently switch between a laptop, tablet, and smartphone
- home office environments with consistent ambient light
- individuals who prefer a low-profile, laptop-style typing feel
Not Recommended For
- users who require backlighting for typing in low-light conditions
- anyone needing an adjustable typing angle for ergonomic comfort
- gamers or users who prefer mechanical key switches
- environments with consistently very low light levels
Watch Out For
- No backlighting means you'll be squinting in the dark, unlike many keyboards at this price point.
- The keyboard sits flat with no adjustable feet, so if you prefer an angled typing position, you're out of luck.
- Charging can be insufficient in rooms with less than 200 lux of light, potentially leading to low-power warnings if not exposed to enough light.
- The Logi Bolt USB receiver is not included in the standard $99.99 model, requiring an extra $10 for the business version or a separate purchase for RF connectivity.
- While Logitech claims silent keystrokes, user reviews indicate the keys are not silent, which might be a concern in quiet shared spaces.

What Buyers Say
The most surprising thing about this keyboard is how genuinely hands-off the charging experience is; users report never needing to plug it in, even under typical office lighting. The multi-device switching is also a standout, letting you jump between a laptop, tablet, and phone without a hitch. However, the lack of backlighting is a recurring complaint, making it a no-go for anyone who types in low-light conditions. Also, the fixed, flat typing angle is a dealbreaker for users who prefer an ergonomic tilt.
“Dude, I haven't touched a charging cable for this thing since I got it, and that's wild. But seriously, no backlight? My late-night typing is a total guess-fest.”
Common Praise
- Never having to charge the keyboard via a cable is a truly liberating experience
- Seamlessly switches between up to three paired Bluetooth devices with Easy-Switch buttons
- The low-profile scissor-switch keys offer a comfortable and responsive typing feel
- Its slim 18mm profile and 700g weight make it easy to integrate into a clean desk setup
- Customizable keys via the Logi Options+ app add useful shortcuts for productivity
- The connection is consistently stable with no reported lag or disconnections
Common Complaints
- No backlighting at all, making it impossible to see keys in the dark
- The keyboard has no adjustable tilt, forcing a flat typing position
- The Logi Bolt USB receiver is not included with the standard purchase, which feels like an oversight for the price
- Some users found it didn't charge effectively in very dim artificial light, leading to potential low-power warnings
- The plastic build, while durable, doesn't feel as premium as metal-clad alternatives
Ownership Tips
- The solar charging really works, even with just normal indoor office lighting, you genuinely forget about battery levels.
- Switching between my work laptop and personal tablet is instant, no annoying re-pairing or delays.
- The key travel feels surprisingly good for a slim keyboard, not mushy like some other low-profile options.
- You'll definitely miss backlighting if you ever work past sunset or in a dimly lit room.
- The lack of adjustable feet means you're stuck with a flat angle, which might strain your wrists after a few hours if you prefer a slight incline.

No, the Logitech Signature Slim Solar+ K980 does not feature backlighting.
How long does the battery last in the dark?

Buying Guide
When you're looking at keyboards, especially wireless ones, think about how and where you'll use it. Do you move it around a lot? Do you work in a brightly lit room or often in the dark? The 'solar-powered' bit here means you probably won't ever plug it in, which is a huge convenience, but it comes with trade-offs like no backlighting. Also, consider if you need to connect to multiple devices quickly, as some keyboards make that a pain.
Solar and Artificial Light Powered
This means the keyboard charges itself from any light source, so you theoretically never need to plug it in or replace batteries. It's like a tiny plant on your desk, constantly absorbing energy.
Multi-device Bluetooth Connectivity
If you use a laptop for work, a tablet for browsing, and a phone for quick replies, this lets you switch the keyboard between them with a button press, instead of needing separate keyboards or re-pairing every time.
Scissor-Switch Keys
This refers to the mechanism under each key. Scissor-switches are common in laptops, offering a shallower travel and a quieter, more stable feel compared to traditional membrane keyboards, but not as tactile as mechanical switches.
Alternatives
If you need backlighting or adjustable typing angles, look for keyboards that explicitly list those features, even if they require periodic USB charging.
