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.

Pros & Cons

👍 Pros

Solar charging via any ambient light source genuinely eliminates battery management — no swapping, no charging cables, no dead-keyboard surprises
The Unifying receiver consolidates up to 6 peripherals onto one USB port, cutting dongle clutter to zero on a desk setup
At just 1/3-inch thick, the K750 feels noticeably sleeker than standard-profile desktop keyboards without sacrificing key travel comfort
Concave key caps reduce finger fatigue during extended typing sessions and improve keystroke accuracy versus flat-top designs
Full-size QWERTY layout with standard key spacing means no adaptation period for touch typists switching from any conventional keyboard

👎 Cons

Windows-only official support makes the K750 a poor fit for Mac users or cross-platform households
No keyboard backlighting — dim environments require external lighting or well-practiced touch typing
A keyboard stored face-down or left in a persistently dark workspace will slowly drain the reserve over weeks, requiring a deliberate recharge session
2.4 GHz via USB dongle permanently occupies one USB-A port — a real constraint on laptops or systems with limited USB real estate
No onboard media controls or dedicated shortcut keys beyond the standard layout, limiting workflow customization for power users

Frequently Asked Questions

Does the K750 actually charge under regular indoor office lighting?

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.

How long does the battery reserve last in complete darkness?

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.

What's the wireless range, and does it need a clear line of sight to the receiver?

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.

Can I consolidate other Logitech devices onto the same Unifying receiver?

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.

Does the K750 work with macOS or only Windows?

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.
