Manufacturer description

The Logitech K780 Multi-Device Wireless Keyboard is a full-size, type-on-everything board built for people who move between a computer, a phone, and a tablet all day. Three Easy-Switch keys let you jump between paired devices instantly, and OS Adaptive layouts mean the keyboard automatically recognizes Windows, macOS, iOS, Android, or Chrome OS and remaps its keys and hotkeys to the layout you expect.

Frequently Asked Questions

How many devices can the Logitech K780 connect to at once?

Three. The K780 pairs with up to three devices and switches between them using the dedicated Easy-Switch keys, so you can move from a computer to a tablet to a phone without re-pairing.

Does the K780 work with a Mac, iPad, and iPhone?

Yes. Listed compatibility covers macOS X 10.10 or later, iOS 5 or later, Windows 8 or later, Android 5.0 or later, and Chrome OS. The OS Adaptive feature detects each device and maps keys and shortcuts to that platform's familiar layout.

What does Renewed mean for this keyboard?

Renewed units are pre-owned, inspected, and tested rather than new in retail packaging, so cosmetic condition and included accessories vary. Check the seller's listing for the current renewed guarantee terms.

How long does the battery last and do I have to recharge it?

Logitech quotes roughly two years of battery life, calculated on an estimated two million keystrokes per year in an office environment, and states user experience may vary. It runs on batteries rather than a recharge cycle, so there is no cable to manage.

Do I need a Logitech mouse to use the K780?

No. The K780 works on its own as a standard wireless keyboard. A compatible Logitech FLOW mouse is only required for the cross-computer feature that lets you type, copy, paste, and move files between linked computers, and that mouse is sold separately.
