The Logitech K400 Plus is a compact wireless keyboard with an integrated touchpad — ideal for living‑room PCs, media centers, or any setup where you want keyboard + mouse functionality without extra devices. It brings convenience and comfort to browsing, streaming, typing, or casual work from the couch or desk, removing the need for a separate mouse.

Key Features

• Keyboard + built‑in touchpad: combines typing and pointer control in one device, eliminating the need for a separate mouse.

• Wireless 2.4 GHz connection (Logitech Unifying) with up to 10 m range: offers stable, lag‑free control over a decent distance.

• Long battery life — up to 18 months on 2× AA batteries: reduces maintenance and ensures long‑term use without frequent battery changes.

• Quiet keys and low typing noise (~ ≤ 55 dBA): comfortable for extended typing sessions or shared/home environments where you don’t want loud clicks.

• Compact, slim design & spill-resistant build: lightweight (~390 g with batteries), easy to place on lap or small desks — handy for media‑center or small‑space setups.

• Media and shortcut keys + easy plug‑and‑play setup: volume/mute keys, hotkeys compatible with Windows and Android, and simple setup via USB receiver — works right out of the box.

• Broad OS compatibility: works with Windows, Android, Chrome OS (and any device that supports external USB keyboards), making it flexible for laptops, desktops, or TV‑PC setups.
