No, the Logitech K400 is not Bluetooth. The K400 and K400 Plus use a USB wireless receiver, so you connect the receiver to the computer instead of pairing the keyboard through Bluetooth settings.
That distinction matters if you're using a TV, mini PC, or tablet. A device without a compatible USB port may need an adapter or a different keyboard.
Is the Logitech K400 Bluetooth or wireless?
The Logitech K400 is wireless, but it does not use Bluetooth. Its connection runs through a USB receiver, which needs to be plugged into the device you want to control.
The original K400 uses a Logitech Unifying receiver. The K400 Plus also uses a Unifying receiver, according to Logitech's product details.
Wireless describes the lack of a keyboard cable. Bluetooth is one way to connect wirelessly, while a USB receiver is another.
For a wired alternative, see our wired keyboard guide.
How do you connect a Logitech K400?
Plug the keyboard's USB receiver into a compatible USB port. Then switch on the keyboard and check that the device recognizes it.
For the K400 Plus, Logitech describes setup as plug-and-play with its Unifying receiver. The K400's instructions also describe plugging its receiver into a laptop.
If you can't find the receiver, check the keyboard packaging and any storage areas indicated by its instructions. The K400 Plus information notes that a receiver may be inside a mouse's battery compartment or attached within the packaging.
Don't keep searching for the keyboard in Bluetooth settings. The K400 won't show up there because its receiver handles the wireless connection.
Can you pair the Logitech K400 in Bluetooth settings?
No, the Logitech K400 cannot be paired through Bluetooth settings. Its USB receiver is the required connection method.
If you need a keyboard that connects directly through Bluetooth, compare options such as a large print Bluetooth keyboard. Check the keyboard's supported devices and operating systems before choosing one.
Will the K400 work with a mini PC or TV?
It can suit a mini PC or computer connected to a TV if the device supports the receiver and keyboard. The K400 Plus is designed for PC-to-TV control and has a built-in touchpad for pointing without a separate mouse.
The K400 Plus supports Windows, Android, and Chrome OS according to its product details. Logitech lists Windows versions for the original K400, so check compatibility against your specific computer before buying.
A USB port is part of the setup. If your mini PC has only USB-C ports, check whether a compatible adapter will let it recognize the receiver.
For help with the keys and touchpad after connecting, see how to use a Logitech K400 Plus keyboard. Our Logitech K400 Plus keyboard review covers that model in more detail.
Which Logitech K400 should you consider?
Choose based on the exact model and your device's compatibility. Both K400 options below use a USB receiver rather than Bluetooth.
The K400 Plus is aimed at PC-connected TV use and includes a built-in touchpad. The original K400 also combines a keyboard with a touchpad and uses a USB receiver.
The K400 and K400 Plus are related models, but their details differ. See Logitech K400 vs K400 Plus to compare them.
What should you do if the receiver is missing?
Find the exact keyboard model before looking for a replacement receiver. A receiver that fits another Logitech keyboard may not work with your K400.
Check the model label on the keyboard or its packaging, then compare the receiver type and compatibility. Our guide to Logitech K400 dongle replacement explains what to check.
If you'd rather replace the whole setup, consider how you'll use the keyboard and pointing device. A silent wireless mouse can suit a separate mouse setup, while the K400's built-in touchpad avoids needing one.
Is the Logitech K400 Bluetooth?
For anyone asking, “is the Logitech K400 Bluetooth?” the answer is no: it connects through a USB receiver. Choose the K400 if your device can use that receiver; choose a Bluetooth keyboard if direct Bluetooth pairing is a requirement.
