Logitech K400 Plus Wireless Touch TV Keyboard for PC-Connected TV - Black

Bottom line: The Logitech K400 Plus Wireless Touch TV Keyboard for PC-Connected TV ($29.99 on Amazon as of 2026-11-07 11:20 UTC): Built-in 3.5-inch touchpad replaces a separate mouse on the couch; main trade-off: keys are not backlit, so dark-room typing is guesswork.

SpecPicks Verdict

SpecPicks scored Logitech K400 Plus Wireless Touch TV Keyboard for PC-Connected TV 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

Does the K400 Plus work without Bluetooth?

Yes. It connects through the included Logitech Unifying receiver, which plugs into a USB port and works immediately with no Bluetooth pairing. Bluetooth is not supported on this model; the K830 offers USB and Bluetooth if you need it.

How long does the battery last and what type does it take?

Logitech rates battery life at up to 18 months, and there is an on/off button to extend it further. The batteries are user-replaceable rather than rechargeable, so no charging cable is required.

Will it work with my smart TV or Mac?

Official compatibility is Windows 7, Windows 8, Windows 10 and later, Android 7 or later, and Chrome OS. It is designed for a PC connected to your TV rather than a standalone smart TV, and macOS is not on the supported list.

How far away from the PC can I sit?

Wireless range is rated up to 33 ft (10 meters), which covers a typical living room from couch to media cabinet. Walls and cabinet doors between the receiver and keyboard can reduce that figure.
