The Logitech K400 Plus is a wireless keyboard with a built-in touchpad, designed to control a TV-connected PC from the couch across a room-size distance. A 2.4GHz Logitech Unifying receiver plugs into a USB-A port on the PC and pairs with the keyboard for a wireless range of up to 33 feet. Battery life on two AA cells reaches 18 months of average use before a swap. Media hotkeys, an on/off switch, and spill resistance round out the design.

The perfect keyboard for use with your TV and beyond
The category the K400 Plus fits into is the HTPC keyboard, meaning a keyboard designed for a home theater PC rather than a desk PC. A Mac Mini, an Intel NUC, or an old laptop plugged into a TV as a media server benefits from a keyboard-touchpad combo that works from the couch without a mouse pad on the coffee table.
The layout on the keyboard follows a compact laptop-style design with a full QWERTY keyboard, arrow keys, and media hotkeys for volume, mute, and playback control. A 3.5-inch touchpad is positioned above the right side of the keyboard, with a second dedicated left-click button on the top-left corner for two-handed navigation while typing. Quiet-touch keys keep typing volume below 55 dBA, which is important on a couch setup where anyone else in the room can hear every keystroke.
