The key feature of the KM-B9 Wireless Keyboard is versatility. Keyboard works with devices based on Windows, Android and iOS system. Pairing KM-B9 Keyboard with devices (with different systems) is very easy. Just turn ON your keyboard, and on the tablet, smartphone, TV Box or other device turn on bluetooth. In addition, on the KM-B9 Keyboard you need to press the combination of buttons: Fn (function key) + C. After pairing, the LED (in the right corner) lights up in blue. Also on the keyboard, there are keys that in conjunction with the function button (Fn) adapt the keyboard to work in the system: Android (Q), Windows (W) and iOS (E).

We tested the keyboard with various devices (smartphone, tablet, Windows mini PC, Android TV Box) and various systems (Android and Windows), and we didn’t have a problem with the keyboard and push keys as well as the combination of buttons (with the function button). Another advantage is also the built-in 140mAh battery, which allows you to use the keyboard for about 160 hours. The only drawback is that the keyboard has an English layout or recognizing only English letters, so in another language, you will not be able to write properly.

If you are looking for a good universal keyboard that will work with many systems and devices, KM-B9 is certainly for you. It is very well made (aluminum alloy) and looks very aesthetic. It’s also small for easy portability, but you can not forget the mouse. That’s right, we lack the built-in touchpad. Then it would be enough to pack the keyboard into the backpack and that’s it. Of course, if you use the touch screen (tablet, smartphone) you can navigate your finger. If you use a mini PC / TV Box the mouse (air mouse) is indispensable. Of course, this does not change the fact that we recommend AUKEY KM-B9 Wireless Portable Bluetooth Keyboard.
