Logitech Wireless Touch Keyboard k400

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.

Tap happiness

2 million keystrokes. Every day.

That’s how much the average person types every year, according to a study by Harvard. (Dennerlein 2006)

If you sit at your computer hour after hour, day after day, all those key presses can really add up. Fortunately, you can do something about it. Logitech keyboards have a variety of comfort features to help keep your body happy.

Zero Degree Tilt™: A real natural

Chances are your standard keyboard makes you take some non-standard positions. You see, traditional keyboards have higher keys in the back than the front, causing you have to angle your palms and fingers upward.

Our keyboards with Zero Degree Tilt™, on the other hand, have a flat design that lets your wrists stay in a more neutral position while you type. You won’t need to extend your wrists as much, either.

Perfectly PerfectStroke

Logitech PerfectStroke™ key system combines the benefits of a laptop keyboard with those of a stand-alone keyboard to give you a perfectly pleasant typing experience.

Clickety-clack. For those of you old enough to remember, it isn’t the sound of that old electric typewriter that you miss so much, it’s the way the keys felt under your fingers.

The Logitech® Unifying receiver takes convenience a step further.

The Logitech® Unifying receiver is a tiny, leave-in wireless receiver. Smaller than most coins, the Unifying receiver not only makes it easy to use a wireless keyboard, mouse, or number pad, it also works with up to six devices.

Plug it in

Forget about it

The Unifying receiver is small and always ready. So small, in fact, you can leave it plugged into your USB port when you’re on the move—without worrying about breaking or losing it.

Add to it

You can mix, match, upgrade, or replace up to six devices—now or in the future—using just one USB port.

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.*
