Logitech K400 Plus Wireless Touch Keyboard, Black – Model 920-007119
The Logitech K400 Plus is a compact wireless keyboard with an integrated touchpad, built for controlling a laptop, desktop, smart TV, or tablet from a distance. A single Logitech Unifying receiver handles the connection over 2.4 GHz, holding steady up to 10 m (33 ft) away, which covers most living rooms and office layouts. The 3.5-inch touchpad on the right side delivers full cursor and click control, removing the need for a separate mouse. Power comes from 2 x AA batteries, rated for up to 18 months of use, and every key stays under 55 dBA, so typing doesn’t carry across a quiet room. It’s a practical pick for anyone who wants one device instead of two cluttering a desk or coffee table.
