The Logitech® Wireless Touch Keyboard K400 Plus lets you experience PC-to-TV entertainment the way you Watch video, browse the web, chat with friends and much more. The all-in-one keyboard with touchpad ends the hassle—and clutter—of multiple devices. And a 10-meter (33-foot)¹ wireless range ensures your fun won’t be interrupted. Comfortable, quiet keys and a large (3.5-inch) touchpad make navigating entertainment effortless. Even setup is a snap thanks to the tiny, plug-and-play Unifying receiver. The 18-month² battery life means you might even forget the keyboard needs batteries. 1 Wireless range may vary depending on operating environment and computer setup. ² Assumes up to two hours typing per day. Actual battery life will vary with use, settings and environmental conditions.
