Overview

The Logitech K750 Wireless Solar Keyboard solves a mundane but persistent annoyance: dead batteries at the worst possible moment. The solar panel built into the top face of the keyboard harvests energy from any ambient light source — overhead office fluorescents, a nearby LED desk lamp, or natural window light — keeping the internal reserve continuously topped up. Logitech rates the stored charge for a minimum of 3 months of operation in complete darkness, which means evenings, weekends, and extended absences pose no risk of a dead keyboard on return. Wireless connectivity runs over 2.4 GHz through the tiny Unifying USB receiver at up to 33 feet, with the same low-latency reliability as a corded connection.

Build-wise, the K750 is genuinely slim at just 1/3-inch thick — a real aesthetic and ergonomic upgrade over standard desktop keyboards. The Logitech-exclusive concave key caps cup each finger strike slightly, which translates to quieter, more accurate typing and reduced fatigue over long sessions. The full-size QWERTY layout means zero relearning curve from any conventional keyboard. One Unifying receiver handles up to 6 compatible Logitech peripherals simultaneously, so pairing a matching wireless mouse eliminates the last USB dongle from your desk. The K750 is squarely a Windows machine — Mac users will find limited official support and key-mapping inconsistencies that make it the wrong choice outside a PC environment.

Frequently Asked Questions

Yes, reliably. Any light source works — fluorescent ceiling fixtures, LED desk lamps, or a window nearby. Logitech's downloadable Solar App lets you monitor charge levels in real time so you always know where you stand.
At least 3 months per Logitech's specification. That means weekends, vacations, or leaving the keyboard in a drawer won't leave you with a dead board when you return.
The Logitech Unifying receiver provides up to 33 feet of range and operates reliably through desks and obstacles — no line-of-sight required at typical desktop distances.
Yes. One Unifying receiver supports up to 6 compatible Logitech peripherals simultaneously — a mouse, presenter, or other keyboards can all share a single USB port.
The K750 is officially designed and supported for Windows 10/11 and later only. While it may function as a basic HID keyboard on macOS, Windows-specific keys won't map correctly and full feature support is not guaranteed.
