The Logitech K400 Plus is a mediocre wireless keyboard with an integrated trackpad designed for using with a smart TV or HTPC. The all-plastic board shows quite a lot of flex and torsion, and its ABS keycaps feel slippery, but it feels light to type on. It isn’t a good choice for programmers or gamers due to the lack of programmable keys and backlighting, but it’s decent for office use as its typing noise is very quiet. Also, it has dedicated volume control keys and a built-in trackpad, which is helpful for use with a TV or HTPC.
Our Verdict
6.0
Gaming
The Logitech K400 Plus isn’t designed for gaming. Although it has a low pre-travel distance and it doesn’t require much force to actuate each key, it has no macro-programmable keys or backlighting, and its latency is fairly high.
Pros
-
Decent ergonomics.
See our Gaming Recommendations
3. 4
Mobile/Tablet
The Logitech K400 Plus doesn’t support Bluetooth, so it isn’t suitable for mobile devices.
7.1
Office
The Logitech K400 Plus is a decent keyboard for the office. Its low profile design shouldn’t cause much fatigue, but the small spacing between keys may cause a lot of typos. On the plus side, it’s very quiet and shouldn’t annoy those around you.
Cons
-
Compact and tight key layout.
-
No multi-device pairing.
-
Poor software support.
See our Office Recommendations
6.0
Programming
The Logitech K400 Plus is inadequate for programming. Although it has decent ergonomics, it lacks backlighting and you can’t program macros to any of the keys. On the upside, it’s compatible with macOS and Linux, although only partially.
Pros
-
Decent ergonomics.
See our Programming Recommendations
3.4
Entertainment / HTPC
The Logitech K400 Plus scores low for home theatre PC setups since it doesn’t have Bluetooth or backlighting. However, if you don’t care about those features, the Logitech K400 Plus has a built-in trackpad to easily navigate your PC without a mouse. Also, it has volume control buttons and media hotkeys. There’s a left mouse click button on the top left of the keyboard, so you can navigate the trackpad with your right thumb and click with your left.
Cons
-
No backlighting.
-
Doesn’t support a Bluetooth connection.

No multi-device pairing.

Differences Between Sizes And Variants
The Logitech K400 Plus keyboard is available in both black and white, but the white model seems to only be available in some regions. Although we tested the black variant, we expect the white one to perform the same. You can see our unit’s label here.
Compared To Other Keyboards
The Logitech K400 Plus serves its purpose as a wireless media keyboard with a trackpad, and it’s designed to use on the couch while connected to a smart TV. It’s very similar to the AmazonBasics K4R and the Corsair K83 Wireless, but it might provide better value for some users. For other options, see our recommendations for the best keyboards, the best wireless keyboards, and the best keyboards for writers.

The Logitech K380 is a better keyboard than the Logitech K400 Plus. The K380’s compact size is easier to travel with, and it can connect to any mobile device with Bluetooth support, unlike the K400 Plus. However, the K400 Plus does have a trackpad which makes it more ideal for a smart TV set up.

The Logitech MX Keys is a better keyboard than the Logitech K400 Plus. The MX Keys has a rechargeable battery and can pair with up to three devices at once via Bluetooth, unlike the K400 Plus that uses AA batteries and doesn’t support Bluetooth. The MX Keys also has a built-in brightness sensor that will turn on backlighting to help you type even in darker rooms. However, the MX Keys has a Numpad instead of a trackpad, so you would need to have an accompanying mouse if you wanted to use it with a home theater setup.

The Logitech K780 is overall a better keyboard than the Logitech K400 Plus. Unlike the K400, the K780 can pair with up to three devices at once via Bluetooth. The K780 also features a built-in stand for phones or tablets, making it the better choice for typing on a mobile device. On the other hand, the K400 Plus is better for a home theater setup thanks to its integrated trackpad and is designed to be used on your lap.

The Lenovo ThinkPad TrackPoint Keyboard II and the Logitech K400 Plus are compact boards with integrated mouse controls. While the Logitech uses a trackpad to move the cursor, the Lenovo uses a rubber pointing stick above the B key like Lenovo laptops tend to have. The Lenovo is better for use with mobile devices and tablets thanks to its Bluetooth support, but unfortunately, it can only pair to one device via Bluetooth and one via USB receiver, which may not be enough for some people. Neither board has backlighting, which isn’t ideal if you need to use it in the dark.
Searching

The AmazonBasics K4R and the Logitech K400 Plus both have a built-in trackpad in place of a Numpad. They’re very similar keyboards, but the Logitech requires less force to actuate a key, and it has a second left-click button on the top left of the keyboard. Also, unlike the AmazonBasics, the Logitech has a companion software that allows you to make some customizations to the keyboard.
Searching

The Corsair K83 Wireless is a better multimedia keyboard than the Logitech K400 Plus. The Corsair looks and feels better built, and, unlike the Logitech, it has backlighting and Bluetooth support. However, the Logitech might provide better value for some users since it’s more budget-friendly.
Searching
Finding Store
The iClever Tri-Folding Keyboard BK08 is better than the Logitech K400 Plus for mobile devices, thanks to its Bluetooth support and better portability. The Logitech isn’t designed for mobile devices, but it has better ergonomics due to its slight incline and it has a companion software that allows you to make some customizations to the keyboard.

The Logitech K480 is better than the Logitech K400 Plus for mobile devices thanks to its Bluetooth support and its cradle for phones and tablets. However, the K400 Plus is better for office uses due to its better ergonomics and typing quality, and its better suited for home theater setups thanks to its built-in trackpad.

This keyboard is similar in size to most TKL keyboards, but it includes a built-in trackpad like other entertainment keyboards. It’s fairly light and is small enough to use on your lap when connected to a smart TV.
Keycap Material
ABS
Update 10/29/2021: We downgraded the build quality score from 7 to 6 because its build feels more like the AmazonBasics K4R, and it feels cheap.
The build quality is mediocre. Its plastic frame gives a lot of flex and torsion, which isn’t great, but it doesn’t feel as though it’s going to snap in half. The keys aren’t stable, the spacebar rattles, plus the left and right trackpad buttons feel loose.
Note: While there are many reports of people having issues with the trackpad not scrolling well and registering double clicks, we didn’t experience any issues with the trackpad while testing the Logitech K400 Plus. If you own it and have experienced issues, let us know in the discussions.

The ergonomics are decent. Although there aren’t any incline settings or an included wrist rest, its low-profile design shouldn’t cause much fatigue. The keys are quite close to each other, but your hand should still feel comfortable and not too cramped.

The Logitech K400 Plus has dedicated volume control keys, and it uses hotkeys for media control. There’s also a left-click button on the top left so you can navigate the trackpad with your right thumb and click with your left. Although there’s no Windows Key lock button on the keyboard, you can disable it in the Logitech Options software. However, you need to open the software each time you want to toggle the lock on or off since you can’t remap any of the hotkeys to do it. If you want a board with a TrackPoint instead of a trackpad, check out the Lenovo ThinkPad TrackPoint Keyboard II.
This keyboard also has an integrated trackpad. Some people have reported experiencing issues with it, but we didn’t experience them during testing, though we don’t test the trackpad as part of our test bench.

The Logitech K400 Plus keyboard uses rubber dome switches that feel like scissor switches and require a bit of force to actuate, though the overall feeling remains light. Due to the membrane switches, pressing a key can feel a bit mushy.
The typing quality is okay. The ABS plastic keycaps feel slippery, and they also feel a bit mushy to type on due to the membrane switch. There isn’t much space between each key, so the risk of typos is high since it might be hard to tell when your finger is in-between two keys. On the plus side, the keys feel pretty stable and the low profile design shouldn’t cause much fatigue.

Packaging and Contents
Keyboard comes in standard teal box . On the front surface there is an image of the keyboard, as well as information that the device can work up to 18 months without replacing batteries, and that it is compatible with OS Windows / Chrome OS / Android.
On the back there is some information about the main advantages of the device.
Inside the box is a Logitech K400 plus keyboard, an external USB module (Logitech Unfying), instructions and a warranty card.
Of course, you can’t call a rich delivery package, but we have everything you need to start working immediately after removing the device from the box. The manufacturer even put two AA batteries so that the user can start using the device immediately after unpacking.
Design
The Logitech K400 plus has no frills in design, it looks nice and simple. The keyboard is made of fairly durable, textured plastic, without glossy inserts, plain gray, with the exception of two yellow inserts. I liked that such plastic does not particularly collect dust.
Form factor – rounded rectangle. The side faces are also rounded.
The keyboard uses membrane type buttons, the keycaps themselves have the following dimensions:
Alphanumeric buttons – 17×17 mm, and this is at the base, and the contact part has a size of 15×15 mm;
Top row of function keys – 16 x 10 mm (at the base), 14 x 9 mm (contact part)
Pressing the buttons is silent, with a well-defined tactile feedback.
Logitech K400 plus is a multimedia keyboard, in which, in addition to the main keys, there are several additional ones to control the audio player, below which there is a fairly large touchpad. At the bottom of the touchpad, separated by a yellow line, are two mechanical control buttons (imitating the left and right mouse buttons).
The back of the keyboard is made of matte gray plastic, it has 4 rubber feet that prevent the device from sliding on the table surface, fixing the cover, 6 fixing screws and printed model name “K400+”.
At the top there is a special ledge, inside which the manufacturer placed a container for two AA batteries and a compartment for storing the Logitech Unfying receiver.
Virtually all ends of the keyboard are absolutely clean, with the exception of the front. They don’t have any switches.
There is an on/off switch on the front of the keyboard. The manufacturer says that if you use this power button, you can increase the battery life up to 18 months.
In general, the Logitech K400 plus is a pretty well thought out device. It has fairly small dimensions (354.3×139.9×23.5 mm) and low weight (380 g), but the manufacturer was able to maintain the full size of the keys. There are no special complaints about the build quality of the keyboard, no visible defects were found during visual inspection. I would like to say that the assembly and execution are good, as befits Logitech.
At work
The process of pairing the keyboard with the computer did not cause any difficulties. You just need to install the module in the USB port and turn on the keyboard.
The range of the keyboard is very large, the device can be controlled from almost anywhere in a fairly large room.
It should be noted right away that there are some inconveniences associated with typing. Still, the manufacturer of this keyboard pursued other goals for its use. It is more convenient for me to type text on a full-fledged keyboard, although there are no particular difficulties with the Logitech K400 plus. The keys work almost silently and softly.
In order to expand the functionality of the keyboard, the manufacturer has installed several additional keys, the main purpose of which is to automate the performance of certain functions.
So, the keyboard has the [Fn] key (in place of the [Left Windows] button), the key combinations with which can perform the following actions:
- [Fn] + [Left Arrow] – start screen;
- [Fn] + [Right Arrow] – end;
- [Fn] + [Up arrow] – scroll the page up;
- [Fn] + [Down Arrow] – scroll down the page.
- [Fn] + [Backspace] – screenshot;
- [Fn] + [Ins] – sleep mode;
- [Fn] + [Caps Lock] – scroll lock;
If desired, in the proprietary Logitech Options application, you can reassign these keys.
In addition, there is a volume control unit and an additional yellow button that performs the function of the left mouse click.
And, of course, the touchpad is the most important element of the keyboard, because it is with its help that you can conveniently control the cursor on the screen. Undoubtedly, it is much more convenient to drive the cursor with the help of an air mouse, but the possibilities of the mouse are limited, because. it does not have a full-fledged built-in keyboard, and as a result, it is not as versatile and practical as a keyboard with a touchpad.
Advantages
- Compact size of the device, but the full size of the keys;
- Large and responsive Touchpad with multi-touch support;
- Decent build quality;
- Wireless;
- Instant install;
- Functionality;
- Autonomy;
- Range;
- Logitech Unfying receiver;
- Ability to reassign function keys.
Disadvantages
- Lack of informative LED indicators (CapsLock, power, battery level).
Conclusion
As mentioned at the beginning of the review, the main purpose of the Logitech K400 plus keyboard is to work in conjunction with multimedia devices, and it copes with this task perfectly.
