Complete pairing in your device settings, press any key to wake, or charge for 15-20 minutes. Factory reset: Hold FN + BACKSPACE for 5 seconds.

How long does the battery last?

Approximately 48 hours with RGB enabled, 200+ hours with RGB disabled. Battery life varies based on RGB brightness and connection mode.

Can I use this while charging?

Yes, connect USB-C cable and continue typing. Charging takes approximately 3 hours to full capacity.

How many devices can I pair?

Three Bluetooth devices (FN + Q/W/E). Switch between them instantly using the same key combinations.

Does this work with iPad/Android tablets?

Yes, connects via Bluetooth or USB-C (with compatible adapter) to any device supporting external keyboards.

What's the difference between wired and 2.4GHz modes?

Wired provides unlimited power and zero battery concerns. 2.4GHz offers wireless freedom with gaming-grade latency (typically 1-3ms). Bluetooth adds multi-device switching but slightly higher latency (8-15ms).
