Logitech Signature Slim Solar+ K980 — Light-Powered Wireless Keyboard, US International, Graphite
Solar poweredNo batteries, no cableEasy-Switch ×3AI launch key
The Logitech Signature Slim Solar+ K980 (920-013764) is a full-size wireless keyboard that never needs charging: Logi LightCharge harvests energy from daylight and ordinary indoor lighting, so as long as the room is lit you simply type. Logitech rates the reserve at up to four months in complete darkness, and the strip needs at least 200 lux to charge — about the light level of a normal working desk. It is 20.2 mm thin with laptop-style typing, a full number pad, multi-OS printed legends for Windows, macOS and ChromeOS, a customisable Action key and a dedicated AI launch key that opens Copilot on Windows or Gemini on ChromeOS. It pairs over Bluetooth Low Energy and switches between three devices. This part number is the US International layout in graphite. In the box: keyboard and documentation.
Compatibility — check before buying:
This keyboard is Bluetooth Low Energy only — no receiver is included; a Logi Bolt USB receiver is sold separately for computers without Bluetooth. It works with Windows 10/11, macOS 12+, Linux, ChromeOS, iPadOS/iOS 15+ and Android 12+. There is no battery to replace and no charging port: it needs light. In a windowless room or a very dim office the reserve runs to about four months, then it needs a lit desk again. The AI key opens Microsoft Copilot on Windows or Gemini on ChromeOS where available — the AI service itself may need its own account, and the key can be remapped in Logi Options+. Layout: US International QWERTY is the layout most people in Cyprus type on: wide Enter key, @ above 2. If your current keyboard is UK layout, the Enter key changes shape and a few symbols move, but letters and numbers are identical.

Frequently Asked Questions
Does it need direct sunlight?
No. Logitech specifies 200 lux, which a normally lit desk or office already provides. Direct sun is not required.
What happens if I work in the dark?
It runs from its reserve, which Logitech rates at up to four months of complete darkness. Put it back under normal light and it recharges itself.
Can I use it without Bluetooth?
Not out of the box — it is Bluetooth Low Energy only. A Logi Bolt USB receiver is available separately for computers without Bluetooth.
What does the AI key do?
It opens Microsoft Copilot on Windows or Gemini on ChromeOS if available on your device; the AI service may need its own subscription. The key can be remapped in Logi Options+.
Singular Expert Insight
The Solar+ K980 answers the one real annoyance of a wireless keyboard — power. If your desk has daylight or normal office lighting, this is the board you never think about again. If you want backlighting or mechanical feel instead, look at MX Keys S or MX Mechanical. See our
keyboards and pair it with a Signature mouse from our
wireless mice; tell us the layout you type on and we will confirm the code.
Buyer’s Guide
Buy it if
You want a full-size wireless keyboard that charges itself from room light, switches between three devices and never needs a cable or batteries, in US International layout.
Skip it if
You need backlighting, a USB receiver in the box, mechanical switches, or you work in a genuinely dark room for months at a time.
Also consider
Logitech MX Keys S for a backlit full-size keyboard, or the Signature Slim K950 combo with a mouse included.
