Powering your wireless keyboard

More power to you

No one likes to run out of batteries. It’s a hassle. Scouring the house for new ones. Finding two that still have juice. Even making an extra trip to the store. At Logitech, we’re doing everything we can to make the hassle of replacing batteries hassle-free. 


Batteries? What batteries?

Wireless keyboards let you avoid the inconvenience of cords. But unlike a corded keyboard (which is powered via USB and your computer), wireless keyboards use batteries, and batteries do run out of power. 

Don’t even want to think about changing batteries? We’ve got just what you need. You can choose a keyboard with a battery life of 15 months—or even three years—and practically eliminate the hassle and expense of changing batteries.*


Charge on

If rechargeable is more your style, we’ve got those too. You just put your keyboard in its charging base. It’s that easy. (Plus it’s good for the planet.)

Laser sensors: A controlling interest

Sensing the details

What does a mouse do? Fundamentally, it allows you to control your cursor. And the best measure of cursor control is the accuracy with which the mouse translates the movements you make with your hand. 

How precise is your mouse? Logitech mice use advanced sensors to make sure that whether you’re clicking links, dragging text, or opening new apps—that whatever you’re doing—your computing experience is seamless. 

We achieve precision by designing miniature sensors. These sensors take lots of little pictures of the surface below the mouse, interpret those pictures, and translate the movement your hand makes into movement on your screen.


Sensitive to your needs

Some people just need a mouse that works. Others need a mouse that can track on many surfaces. And gamers need a mouse that can give them game-changing precision at any hand speed.


Details, details

There are two kinds of sensors: optical and laser.

Mice with optical sensors track the surfaces beneath them using the available light and an LED lamp.

In 2004, Logitech introduced the first mouse with laser tracking. Laser sensors, compared to optical, produce far more illumination—both of the surface and of the contrast created by, literally, specs of dust on the surface—revealing a wealth of details even on glossy surfaces like highly polished wood. And that means your mouse can track motion precisely on many surfaces, without lags or jitter.


Glass. The final frontier.

Logitech mice that are built with Logitech® Darkfield Laser Tracking™ use the smallest possible details to create a micro-road map of the surface. That means these mice can track on glass.*

Gaming-grade control

If you’re an expert gamer, pixel-perfect tracking can mean the difference between victory and defeat. Our mice with gaming-grade laser sensors can track at speeds all the way up to 5700 dpi. So when the game is on the line, you’ll get maximum precision, blinding speed, and ultra-smooth tracking.

See all mice with a gaming-grade laser.


Track tested

We rigorously test all of our laser mice on a wide variety of surfaces to make sure your mouse is free of tracking flaws.

* Mice with Logitech® Darkfield Laser Technology cannot track on glass that is 4 mm thick or less, which is not much larger than the head of a pin. 


The keys to wireless convenience.

You can control your computer from across the room. And be more productive and comfortable on the go. Logitech wireless keyboards give you the freedom to do more, in more places—without the clutter of cords. From basic to Bluetooth, we’ve got plenty of options to choose from. But don’t worry—we’re here to untangle all the terminology and technology.

The power player: Advanced 2.4 GHz

For the best-of-the-best wireless connection, Logitech® Advanced 2.4 GHz wireless gives you the reliability of a cord with cordless convenience and freedom. Advanced 2.4 GHz wireless virtually eliminates delays and dropouts—even in the busiest wireless environments, such as a high-tech office. 

In addition, Advanced 2.4 GHz wireless is designed to optimize battery power. (Many of our keyboards with Advanced 2.4 GHz wireless can offer up to three years of battery life.) 

Your keyboard is automatically paired with your computer. So, you can use your keyboard with the most demanding applications and know that every keystroke you make will be carried out instantaneously. It uses less battery power than other wireless technologies, too

Check out all of our Advanced 2.4 GHz wireless keyboards.


Fast and reliable: 2.4 GHz

The predecessor to Advanced 2.4 GHz wireless, our basic 2.4 GHz wireless keyboards deliver wireless convenience you can count on. 

Thanks to its ability to transmit data in two directions, your keyboard can save power by turning itself off when your PC is dormant. Your keyboard can even sense if there’s wireless interference and change channels to establish the most secure connection.

Have a look at all 2.4 GHz wireless keyboards.


Back to basics: 27 MHz RF

An older favourite, you can use 27 MHz RF up to six feet away from your computer. 

It uses less battery power than devices that operate on higher-frequency bands. And it can keep a secret too—advanced encryption securely transmits your keyboard strokes to the computer.

Comfort Wave Design: The design of comfort

Typing is a big part of daily life. You do it automatically without really thinking about it. But, if you’re like most people, you’re feeling it. That’s what prompted us to rethink keyboard design and create a line of comfortable keyboards that don’t make you relearn how to type, unlike split keyboards.
See all Wave keyboards.

Watch the Wave video.


An idea right at our fingertips

We set out to create a keyboard that didn’t force you to conform to it—but rather one that conformed to you. The idea? A wave-shaped key frame with varying key heights to mirror the varying lengths of your fingers. 

The keys hit by your little fingers would be the highest. Those hit by your middle fingers would be the shortest. You’d be in a more natural position so you wouldn’t need to twist and bend your hands and forearms to type.

Curve + Wave + Palm Rest

Not ones to rest on our laurels, we looked at all of our options. We tried linear designs. Curved designs. Palm rests and no palm rests. And all the possible combinations. When we put them to the test, the clear favorite was the keyboard with curve + wave + palm rest. The Wave keyboard was born.

Details, details

Unlike other curved keyboards, we used consistently sized keys. The subtle 5-degree curve was designed to let your hands open up and take a natural position instead of forcing your wrists to bend. And because each key is the same size and same distance from one another, you wouldn’t need to relearn how to type.

The cushioned, contoured palm rest mirrored the wave-shaped key frame. We added gentle indents to position your hands comfortably on the keyboard and used padded, soft upholstery so you’d have a cushy place to rest your palms when you’re not typing.

Comfort at last

To bring all this comfort to the achy masses, we had to completely redesign nearly every element of the assembly process and our packaging. But the results were worth it. Independent studies show that the Wave keyboards significantly reduce the four major points of discomfort—without causing a noticeable change in typing speed or accuracy.* It’s comfort made easy.

According to studies by two U.S. universities.

    I have a box full of keyboards and mice that looked good until I worked with them for awhile and found reasons to discard them and try something else.
    Finally I found this combo and love it.
    The "Wave" is more comfortable than the Microsoft product I had tried. It really has a natural feel to it and I find problems with getting my fat fingers on the right keys to be greatly reduced.
    The built in palm rest is also superior to those on others that I have tried. It is firmly attached, not clipped on, so it does not flop around or fall off or worse have the clips broken. It is also very comfortable.
    I have also found the mouse to have great response and has a great feel to it.
    All in all, a GREAT combination.
    If I have any cons to post it would be that the overall depth of the keyboard does present some problems if you have limited space. But I would not change it as the advantage of the padded attached palm rest greatly outweigh the negative.

    Logitech's remote keyboard is the best I've been able to find, but that isn't setting the bar too high. I can't comment on their mouse because the last Logitech mouse I had that worked was the old roller ball model.
    In the interest of full disclosure, I am mildly disgraphic (weak nerve signals from finger tips to brain), so I am hard on keyboards. But still, I'd like for one to last three years.
    I work as a research analyst. Maybe Logitech isn't designed to handle that kind of workload?
