Introduction to the Logitech K400 Plus
The K400 Plus is not just a wireless keyboard; it’s a fully integrated media control device. Designed for living room entertainment, this keyboard combines a compact QWERTY layout with a large touchpad, making it a favorite among home media center enthusiasts and casual computer users alike.
Key Features at a Glance:

- Built-in multi-touch touchpad
- Media control hotkeys
- Plug-and-play USB receiver
- Long battery life
- Comfortable, quiet keys
- Lightweight and portable
Design and Build Quality
One of the standout attributes of the K400 Plus is its ergonomic and space-saving design. Weighing only 390 grams and measuring 14 x 5.5 inches, it fits comfortably in your lap, on your desk, or on a couch armrest.
Aesthetic Appeal
The keyboard sports a minimalist look, with rounded corners and a matte black finish. The keys are low-profile and quiet, designed to provide satisfying tactile feedback without being too noisy.
The trackpad is positioned on the right-hand side, offering an intuitive setup for right-handed users. However, left-handed users may require some adjustment time.
Wireless Performance
The K400 Plus offers robust wireless functionality using Logitech’s Unifying Receiver. With a range of up to 10 meters (33 feet), it ensures strong, consistent connectivity without lag or interference.
This makes it ideal for:
- Home theater PC setups
- Conference room presentations
- Wall-mounted computers
- Situations where desk space is limited
Plug-and-Play Simplicity
Installation is as simple as plugging the tiny USB dongle into your computer or smart TV. There’s no need to install drivers or software, though you can use Logitech Options software for customization if desired.
Integrated Touchpad
One of the most significant features of the K400 Plus is its built-in multi-touch touchpad. At 3.5 inches wide, it offers ample space for gestures like scrolling, pinch-to-zoom, and tapping.
Benefits of the Integrated Touchpad:
- Eliminates the need for a separate mouse
- Enhances portability
- Intuitive for web browsing and app navigation
- Works well on smart TVs and Android boxes
The trackpad is responsive, though it lacks the precision of premium standalone touchpads. However, for casual use and media browsing, it performs more than adequately.
Key Layout and Functionality
Despite its compact size, the K400 Plus doesn’t feel cramped. The key travel is moderate, offering a good typing experience. Keys are well-labeled and feature a soft rubber finish that aids in grip and comfort.
Shortcut Keys
The keyboard includes dedicated media control keys such as:
- Play/Pause
- Volume Up/Down
- Mute
- Brightness Control
- Home and Back
These are especially useful for media center environments, letting users control playback without switching screens or grabbing a remote.
Battery Life
Logitech claims up to 18 months of battery life with standard AA batteries—and they aren’t exaggerating. Real-world usage shows that the K400 Plus is remarkably power-efficient. It also features an on/off switch to help conserve battery when not in use.
Some users have reported using the keyboard for over a year without needing to change batteries, depending on usage frequency.
Compatibility
The K400 Plus is highly versatile when it comes to compatibility. It works out of the box with:
- Windows 10, 11, 8, 7
- Chrome OS
- Android TV
- Raspberry Pi
- Some macOS functions (limited touchpad support)
- Smart TVs with USB keyboard support
Unfortunately, it doesn’t support iOS or iPadOS, and some macOS gestures are not recognized due to driver limitations.
