I needed a universal wireless keyboard for different devices. I was looking for an option that could work simultaneously via Bluetooth and USB. I need USB connect to, for example, enter the BIOS of PC before the OS started.
I would also like the keyboard to be able to charge via USB-C. It would be perfect if the keyboard could also function as a regular wired USB keyboard.
As a result of my searches, I found a suitable option.
This is OKLICK 835S.
Pros of this model:
-works with Android, Windows, iOS (mode switching is provided for this)
-works over a radio channel using a USB receiver
-works via Bluetooth with three devices (switching between three devices is provided for this)
-not a high cost, just only $16 USD
-built-in battery and charging via USB-C
-clear operating algorithm, indication and marking
-sleek design and compact dimensions
-looks reliable
-keyboard layout is convenient for me
Cons of this model:
-Quicharge and Poverdelivery chargers are not supported (chargers simply do not see the keyboard and you need to use a computer or some pre-tested 5V power supply)
-it’s not clear which Bluetooth connection of three is active
-it is not clear which OS compatibility mode is active at the moment
-low production standards and assembly quality (casting defect, similar to a crack and some piece of the membrane sheet sticking out of the gap between the halves)
-the legs are glued weakly, the glue is smeared, one leg is already leaving its place
The keyboard is produced, as expected, made in China by Nippon Click Systems Limited.
Overal, its pretty good tool, if you need one keyboard to your "home lab" or like EDC for IT guy.
