After more than a decade of waiting, Logitech has unveiled its latest solar-powered keyboard, the Signature Slim Solar Plus K980. Priced at $99.99, this innovative keyboard continues the legacy of the K760, relying solely on light for power. Unlike traditional keyboards, the K980 does not feature a USB port or swappable batteries. Instead, it is equipped with a solar cell capable of converting both solar and artificial light (with a minimum of 200 lux) into energy to charge its battery.
The K980 boasts an impressive battery life, with Logitech claiming that it can last up to 10 years on a full charge. Even in complete darkness, this keyboard remains functional for up to four months. For users curious about battery maintenance, Logitech spokesperson Melvin Dilanchian confirmed to The Verge that the K980’s battery is “safely user-replaceable,” which means you can easily replace it with spare parts provided by iFixIt.
Beyond its efficient solar charging capabilities, the K980 features a standard full-size layout, complete with Windows and macOS key labels, directional keys, and a numpad. Its function row comes pre-programmed to manage media playback, screen brightness, and volume control. Users can customize secondary features or disable them altogether using the Logi Options Plus app available for both Mac and Windows platforms.
One of the standout features of the K980 is the addition of an AI Launch key. By default, this key opens Copilot on Windows PCs and Gemini on ChromeOS. However, users have the flexibility to customize this key to launch ChatGPT, an AI prompt builder, or assign it to one of Logitech's Smart Actions for quick access to tools like Perplexity. Additionally, the Action Key and several others can be programmed to execute macros, allowing for a personalized typing experience.
The K980 supports pairing with up to three Bluetooth devices, enabling users to switch seamlessly between them with a simple button press. It can also be connected to computers equipped with a Logitech Bolt USB transmitter, although it is worth noting that this transmitter is not included in the package. This multi-device functionality enhances productivity for users who frequently switch between devices.
Unlike previous Logitech models, which featured playful LED indicators for ambient light levels, the K980 uses a straightforward power LED that shifts from green to red when it requires more charging. This design choice encourages users to install the Options Plus app, which provides a detailed indicator of whether there is sufficient light for charging.
As 2025 approaches, the trend toward solar-powered keyboards is gaining traction. Recently, Lenovo introduced its own self-charging wireless keyboard at a similar price point of $99.99, which was first showcased at CES 2025. While the Lenovo model has features that appeal to some users, such as adjustable legs and a spill-resistant design, it lacks the extensive customization options that the K980 offers. Moreover, it includes a USB-C charging port for added convenience.
In summary, the Logitech Signature Slim Solar Plus K980 represents a significant advancement in solar-powered keyboard technology, combining sustainability with user-friendly features. Its long battery life, customizable keys, and multi-device support make it a compelling option for both casual and professional users alike.
