Logitech Signature Slim Solar+ K980 FR: Solar Keyboard Review
- Logitech is betting on the sun with its K980 solar keyboard, a device designed for a decade of wireless use without the need for disposable batteries.
- The promise is compelling: Logitech claims just one hour of sunlight can power the keyboard for weeks.
- We subjected the keyboard to a two-week period of complete darkness, which depleted the battery to 15% and triggered a low-power warning.
Logitech’s Solar Keyboard: A Decade of Wireless Freedom, But Sunlight is Key
Logitech is betting on the sun with its K980 solar keyboard, a device designed for a decade of wireless use without the need for disposable batteries. Released with a minimalist package constructed largely from recycled materials – a clear nod to the company’s sustainability goals – the K980 distinguishes itself with an integrated solar cell capable of recharging from both natural and artificial light.
The promise is compelling: Logitech claims just one hour of sunlight can power the keyboard for weeks. Though, real-world performance reveals a more nuanced picture. Our testing, conducted throughout October and November 2025, demonstrated that light intensity is paramount.While a workstation positioned directly by a window received approximately 1,300 lux of light, a corner office location yielded less than 100 lux, even on a bright day. this difference significantly impacts charging efficiency.
We subjected the keyboard to a two-week period of complete darkness, which depleted the battery to 15% and triggered a low-power warning. The keyboard continued to function after this depletion, but as the days shortened leading into the winter season, it became unable to recharge adequately when positioned away from direct light. This highlights a critical consideration for potential buyers: placement is everything.
Notably, Logitech has eliminated the conventional USB charging port on the K980. Solar power is the sole method of replenishment, reinforcing the commitment to a long-term, environmentally conscious design. The company anticipates a ten-year lifespan for the keyboard,contingent on consistent light exposure. The included user manual provides basic guidance, but understanding the light requirements is crucial for maximizing the K980’s potential.
For those seeking a truly wireless and sustainable keyboard solution,the Logitech K980 presents an intriguing option.However,prospective users should carefully assess their workspace lighting conditions to ensure they can provide the necessary illumination for consistent operation. It’s a bold step towards a more sustainable future for peripherals, but one that demands a little planning.
