Logitech K750 Wireless Solar Keyboard


Our Score:


The reason for this comfort is twofold. The first is the incurve. While most keyboards dip heavily in the middle the K750 keys are more subtle - as if you'd pressed your finger tips gently into a soft surface. This makes them cushion your fingers better and you feel a grip for the keys earlier.

The second element is the action of the keys themselves. For such a thin keyboard there is a remarkable amount of travel, not too much (about 5mm), and the keys then quietly spring back in such a manner than your fingers don't lose contact with the key on the way back up.

The effect this creates is an ability to dance from key to key, there is no stabbing action from one to another. For touch typists this is perfect because the extra duration of contact means your fingers spend less time airborne meaning less chance of losing your positioning and consequently making mistakes. Heavy typists will also be keen to learn that the traditional keyboard weakspot, the space bar, is just as well balanced as the rest of the keys.

Needless to say this review was written on the K750 and while it may be little over 1,000 words, I would have been happy to go on for another 1,000.

All of which doesn't mean the K750 is completely flawless. With its design you'd think it would be targeting an Apple audience, but Logitech has yet to offer Mac drivers. It will work on a Mac, but without the useful Solar App. Furthermore at £69.99 the K750 isn't cheap. That said for what is on offer I wouldn't say it is extortionate, particularly for heavy typists.


The Logitech K750 Solar Keyboard is a wonderful example of smart design, innovation and practicality all combining to make a class leading product. Given the low power consumption of keyboards it is surprising in hindsight that a truly independent, high class wireless design had yet to surface. Now it has we'll find it very hard to go back to wires or batteries. It is hard to admit, but we're genuinely excited about this keyboard. Take one home and we're sure you'll feel exactly the same.

Hey, that's actually really impressive.

Ask them to make an ergonomic version for me, could you? I like a bit of ergo curve on my keyboards.

I absolutely love the idea of this - I can't believe nobody has really nailed this idea before. With feverish excitement, I started to visualise a future where not only the did the panels charge the keyboard, but they wirelessly dripfed back to the PC, which when switched off would return energy to the network, probably making me around £0.02 per annum based on the size of those solar cells.

Anyway, dreamland over, it looks great, the solar doesn't appear to be a gimmic - what's not to like? Well, if they'd added in a backlit keyboard then that would have been 10s across the board for me, especially with user defined colours.

If solar cells can be used so elegantly here, and crucially fairly cheaply here, admittedly for a low drain device I wonder what other peripherals could benefit from a similar approach?

Technology changes, and so sho

Could you elborate on a repeated word in the article?
How can it be Bluetooth and yet only compatible with six 'compatible' peripherals?
It may work on 2.4GHz, but it doesn't sound like Bluetooth.


March 23, 2011, 1:44 pm

Mac compatible?


March 23, 2011, 1:47 pm

No mouse to accompany this product that is also wireless, solar-powered and sexy?


March 23, 2011, 2:08 pm

Such a great idea.
I have to say the issue of having to constantly replace/charge batteries has deterred me from buying any wireless peripherals up to this point but this seems to solve that.
What are your thoughts on whether this technology could be applied to a mouse? Logistics aside (i'm imagining a fingerprint issue on the solar panels), could solar cells power the workings of an optical mouse?

@technology changes

I imagine that it's compatible with up to 6 at the same time through the one bluetooth dongle

I've been using the Logitech k340 wireless on 2aa batteries for over 6 months and they are still going strong.

I have the Logitech Illuminted Keyboard. Its wired but the design appears to be very similar but using an integrated palm wrist and backlit keys.
Typing action is really good. Best keyboard I've had! (and you can change the brightness of the backlight with a single button press)

Can it be used without drivers? I'm thinking about using one at work, and our pc's are locked down.
Also what about using two in close proximity? (we have two pc's at work, for reasons to daft to go into here:)


March 23, 2011, 3:22 pm

Are you sure it is Bluetooth? Sounds more like Logitech 'unifying' receiver technology. Based on my experience of Bluetooth peripherals to date dropping in and out all the time, Bluetooth would put me off. The Logitech wireless tech just works.

Looks amazing. A couple of questions:

1. Is there much input lag? Is it ok for gaming. I use a wireless mouse so I'm not going to go nuts over a couple of miliseconds, but something more substantial could be an issue

2. How does this measure up from a typing comfort perspective with a normal desktop keyboard. I hate typing on laptops and am very much used to typing on desktop keyboard where there is a bit of depth to the keys. Noted that you've said it compares very well to a laptop but how would you compare it to a desktop keyboard?


March 23, 2011, 4:10 pm

Looks superb, really good.

Mac version please Logitech!

Any good for gaming on?
I'm in the market for a good wireless keyboard and mouse (preferbly a combo package)


March 23, 2011, 4:41 pm

As a logitech keyboard user this interests me greatly.

I want one NOW.

Like others allready mentioned, the BT and 2.4GHz doesn't compute... The Logitech Unifying receiver works on RF. Also no BT mentioned on the Logitech site.
Does this keyboard work normaly in the BIOS and during POST?
would you consider this keyboard also good for HTPC (comfortably enough to type while having the board on the legs)?

From Logitech's website:

* Logitech Unifying receiver
* Wireless extender
* Cleaning cloth

@all - apologies for the delay in replying chaps. I've been away much of the day.

In no particular order:

Those who spotted 'Bluetooth' were right. It is indeed Logitech's unifying wireless tech. Apologies it is now corrected and I have added in a line about the input lag after trying it out against some games in response to Energizer Bunny's query. In short: it was excellent.

I mention there is no Mac support at present, but it will still work - just without the app. I've asked this question of Logitech and will update when I get an answer. Whether is will work without any drivers at all (in relation to cjb110's comment) I very much doubt. It's driverless in that is installs itself, but a PC that is locked down is unlikely to allow that.

The keyboard works fine in the bios of the laptop and desktop I tested. That said be sure to check if you have older machines since even USB keyboards can have trouble on some.

As for a mouse... that's an interesting question. I think it presents a bigger challenge. For a start you cover the solar panels when you use it. Secondly a keyboard is a series of tiny inputs whereas a mouse is a long stream of input each time it is used, which I suspect is far more draining. That said I'm sure Logitech will be looking at it if the K750 is the success it deserves to be. I haven't asked it this question because, quite simply, it won't reveal its upcoming product strategies that easily ;)

Finally Deamwalker - yes I think you'd find it ideal in that scenario.


March 23, 2011, 9:52 pm

@Gordon - thanks for the reply/update.

I'm building a new HTPC and I will add this keyboard to my shopping list, so thanks for the review and well done Logitech.


March 23, 2011, 10:49 pm

@Gordon - just tell logitech:

Make it in Mac style Alu and White

Include normal Mac keyboard layout (but include num pad)



March 23, 2011, 10:52 pm

@Kempez I wouldn't be surprised if Logitech isn't keeping its powder dry for a dedicated Mac version.


March 23, 2011, 11:22 pm

Damm you! I just bought a Logitech Dinovo for my home cinema / htpc set up. As I could not find anything else that suited. Still,at least the Dinovo has dual functionality and backlights....


March 24, 2011, 12:29 am

Hope so, I'd buy one! :-)


March 24, 2011, 1:57 am

Such a shame it uses Bluetooth and not their normal unifying receiver! I recently got an Anywhere MX mouse and i don't want another USB port occupied, simply don't have any more on the rig I need it for.


March 24, 2011, 3:02 am

This is one of the very few Logitech keyboards with a decent key layout. The most of Logitech k/bs are just horrible.
