Logitech Just Launched a Solar-Powered Wireless Keyboard That Doesn't Require the Sun

Logitech has reintroduced solar-powered keyboards with the launch of the Signature Slim Solar Plus K980. Priced at $99.99, this keyboard relies solely on light for power, similar to its predecessor, the K760. It lacks a USB port or replaceable batteries, instead using a cell that transforms solar or artificial light into energy. Logitech claims the battery can last up to 10 years and function in darkness for four months once fully charged.

The K980 is available on Amazon, Best Buy, and Logitech's website. When asked about the battery's replaceability, Logitech spokesperson Melvin Dilanchian confirmed it is user-replaceable due to its plastic casing, with spare parts provided by iFixIt. The keyboard features a standard full-size layout with Windows and macOS key labels, directional keys, and a numpad.

Customisation and Connectivity

The function row of the K980 is pre-set for media control, screen brightness, and volume adjustments. Users can customise these functions or disable them entirely using the Logi Options Plus app for Mac or Windows. Additional keys include a mic mute key, camera toggle, and an Action key that can be programmed through the app.

A new AI Launch key is included in the K980. On Windows PCs, it defaults to launching Copilot (Gemini on ChromeOS), but users can customise it to open ChatGPT or an AI prompt builder via Logitech's app. Alternatively, users can assign one of Logitech's Smart Actions to this key.

Design Variants and Pairing Options

The graphite version of the K980 is universal with key labels for both Windows and macOS. North American Mac users have an off-white option without Windows labels at the same price. The keyboard supports pairing with up to three Bluetooth devices, allowing easy switching between them with a button press.

Although it can connect to computers with a Logitech Bolt USB transmitter, one isn't included in the package. Unlike previous models with LED indicators for light sufficiency, the K980 uses a simple power LED that changes from green to red when more charge is needed.

Comparisons and Market Trends

In 2025, companies seem to be revisiting solar technology as Lenovo introduced its self-charging wireless keyboard at CES 2025 for $99.99. Although I haven't tested it yet, Lenovo's model offers features like adjustable legs for tilt and spill resistance that are absent in the K980. It also includes a USB-C charging port as an alternative power source.

Logitech's previous Solar K750 model from 2010 had playful LED indicators showing if there was enough light for charging. The K980 requires installing Logi Options Plus to check light sufficiency instead of using such indicators.

This renewed interest in solar-powered keyboards highlights their potential benefits in sustainability and convenience by reducing reliance on traditional power sources while offering modern customisation options through apps.
