Living-room control

The Logitech Wireless Touch Keyboard K400 Plus combines a full-size key layout with a 3.5-inch touchpad so you can browse, stream and chat from the couch. It connects through a USB Unifying receiver using the 2.4 GHz band and runs on two pre-installed AA batteries rated for up to 18 months of use. The design targets anyone who wants a single input device for a TV-connected PC.

Setup requirements

A spare USB port on a Windows 7, 8, 10 or later machine, an Android 5.0 or later device, or a Chrome OS system is all that is needed to pair the receiver. The ten-metre wireless range lets you sit well back from the screen without signal loss. No separate mouse is required because the integrated touchpad handles cursor control and multi-touch gestures.

Sustained use

The keyboard weighs .86 lb with batteries installed, keeping it light enough for extended lap sessions. Keys are shaped for quiet, comfortable typing during long browsing or streaming periods. Battery life is measured in months rather than days, so the device stays ready for daily living-room use without frequent swaps.

Questions about this item

How long will the two AA batteries last before I need to replace them during daily couch use?

The keyboard runs on two pre-installed AA batteries rated for up to 18 months of typical use.

Does the integrated touchpad stay responsive and cool during extended TV sessions?

The 3.5-inch touchpad has no active cooling and draws minimal power, so it produces no noticeable heat or noise.

Which devices must already have a free USB port for the Unifying receiver to work?

A Windows 7/8/10 or later PC, Android 5.0 or later device, or Chrome OS machine with an available USB port is required.
