Logitech 920-003070 Wireless Touch Keyboard K400 with Touchpad

The Logitech K400 is a compact wireless keyboard purpose-built for one specific use case: controlling a PC, HTPC, or media center connected to a television from across the room. Its defining feature is the integrated 3.5-inch multi-touch touchpad positioned to the right of the key field, which eliminates the need for a separate mouse and consolidates your entire input chain into a single lap-friendly device. Wireless connectivity is handled by Logitech's 2.4 GHz Unifying receiver, which plugs into a USB-A port and establishes a connection instantly with no software installation — the keyboard is operational as soon as the receiver is seated. The rated 10-meter range uses a robust RF protocol that does not require line-of-sight, making it reliable even when the receiving device is tucked inside a media cabinet.

The K400 measures 13.9 x 5.35 x 0.94 inches and weighs 12.7 ounces, making it compact enough to keep on a couch cushion or coffee table without dominating the space. The low-profile membrane keys are quiet — important in a living room environment — and feature bold, high-contrast character printing for readability at a distance. Dedicated media hotkeys provide quick access to volume and playback controls. Battery life is rated at 12 months from two included AA cells, supported by an automatic sleep mode that aggressively conserves power during idle periods. While the K400's official compatibility list covers Windows XP through Windows 8, its standard USB HID compliance means it functions on Windows 10, Windows 11, most Linux distributions, and many Android TV and Raspberry Pi setups. For users building a streamlined media center or simply wanting a no-fuss way to interact with a TV-connected PC, the K400 delivers the essentials without unnecessary complexity.
