Signature Slim Solar+ wireless keyboard K980 - Graphite - English US (QWERTY) — Graphite
FAQs
Does it require direct sunlight to charge?
The keyboard is built with Logi LightCharge technology, meaning it charges using any light source, including indoor office lighting, desk lamps, and indirect natural daylight. It requires a minimum ambient light level of roughly 200 lux to continuously sip power while you work
What happens to the battery if I work in total darkness?
If the keyboard is fully charged, it can operate for up to 4 months in complete darkness. Under normal office or home lighting conditions, the battery continuously tops itself off, resulting in an expected internal battery lifespan of up to 10 years without ever needing a plug
Is there a USB-C or lightning port to charge it if the battery dies?
There are no charging ports or cables included. However, Signature Slim Solar+ features a durable built-in rechargeable battery that serves as a backup when light is not available. Once fully charged, it can last up to four months in complete darkness, ensuring uninterrupted performance even in low-light environments. Thanks to its built-in rechargeable battery, the keyboard is ready to use immediately out of the box, with no need for a charging cable. This also enables longer usage in low-light environments and ensures the keyboard retains power even after extended periods of inactivity, such as returning from a holiday. It's a more practical and reliable solution that delivers true, hassle-free performance without compromising on design or convenience.
Does the K980 have backlit keys?
No, it does not have backlighting. Adding LEDs under the keys would drain power far faster than the built-in solar panels could harvest it.
What is Logi LightCharge technology?
Signature Slim Solar+ is equipped with the unique Logi LightCharge technology which can deliver a true hassle-free power experience with light compared to other keyboards which are using Alkaline batteries or recharged by cable.
Can it connect to multiple devices at the same time?
Yes. It features Logitech's Easy-Switch technology, allowing you to pair the keyboard with up to three separate devices (e.g., your PC, Mac, and iPad). You can instantly jump typing focus between them by pressing the dedicated 1, 2, or 3 channel keys on the function row.
How do I track the solar charging status and battery health?
To see exactly how much energy the solar panel is pulling, you need to download the Logi Options+ software. The app allows you to access the lighting conditions and will tell you if your current desk setup has "sufficient illumination" to charge the battery. You can see the battery charge level in Logi Options+ app as well.
Does it charge when the keyboard is turned off or when I am using it?
Yes, the keyboard is charging all the time when the lighting conditions are optimal (you can check if lighting conditions are optimal in Logi Options+ software). The app will tell you if your current desk setup has "sufficient illumination" to charge the battery. You can see the battery charge level in Logi Options+ app as well.
Can you adjust the typing angle/height of the keyboard?
The K980 is built with a fixed, ultra-slim profile. While there is a slight built-in wedge at the top rear (housing the solar panels) that props it up slightly
What is the typing experience like?
It feels very similar to a modern laptop keyboard. It uses low-profile membrane scissor switches with a slightly scooped keycap design. Keystrokes are highly muted and quiet
