Manufacturer description
The Logitech K400 Wireless Touch Keyboard solves one problem well: driving a TV-connected laptop from across the room. Logitech pairs a full keyboard with a 3.5-inch multi-touch touchpad on a single low-profile deck, so you can type a search, scroll a page, and click a link without reaching for a mouse. The Logitech Unifying receiver plugs into a USB port and works without driver installation, and the 33-foot (10-meter) wireless range covers a typical living room, though Logitech notes range varies with environment and computing conditions. The keys are quiet and low-profile with bold…
SpecPicks Verdict
SpecPicks scored Logitech Wireless Touch Keyboard K400 using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. Logitech's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
How far can I sit from the TV and still use the K400?
