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.
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.
Comfort is key with Logitech keyboards
2 million keystrokes. Every day.
Comfort Wave Design: Curve + Wave + Palm Rest
Your fingers vary in length—but most keyboards treat them all the same. Our Wave keyboards have a gradual wave-shaped contour to support the varying lengths of your fingers and keep the pressure off your fingertips.
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.
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.
Logitech® Unifying receiver
Plug it. Forget it. Add to it. You’ve got the Logitech® Unifying receiver.
And it’s easy to add a compatible wireless keyboard or mouse to the same receiver. Build your ideal combo. Add something. Replace something. It’s as simple as can be and you’ll use only one USB port.
Uniting your setup
Your laptop is convenient. You use it on the couch, in the kitchen, at the coffee shop—wherever you want. Logitech makes your laptop as comfortable as it is convenient with portable mice and notebook-ready keyboards.
Plug it in
With the tiny wireless receiver, there’s no need to plug and unplug when you’re on the move. Or deal with the hassle of multiple receivers. The tiny Logitech® Unifying receiver stays in your notebook and lets you add devices as you need them.
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
It’s fast and easy to add a compatible wireless mouse, keyboard, or number pad to your receiver. You can mix, match, upgrade, or replace up to six devices—now or in the future—using just one USB port.
To connect a new device, you simply open the connection software, click “Pair new device”, and turn the device off and on. That’s it.
A tiny dynamo
The Unifying receiver packs plenty of power. Built with Logitech® Advanced 2.4 GHz wireless connectivity, Logitech mice with the Unifying receiver give you the reliability of a cord—with the freedom of cordless. You’ll enjoy fast data transmission with virtually no delays or dropouts.
Compatible with Logitech® Unifying receivers
Looking for a mouse or keyboard (or number pad) that is Unifying compatible? We’ll help you find the right one.
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.
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.)
