Keyboard A4Tech Fstyler FBX51C — RF Wireless + Bluetooth, Scissor switch, White

A4Tech Fstyler FBX51C is a compact, rechargeable wireless keyboard in white that offers dual connectivity via RF 2.4GHz and Bluetooth. Designed for general desktop and laptop use, it provides a low-profile typing experience with scissor-switch keys and supports multi-OS layouts for Windows, Mac, iOS and Android devices. The keyboard can pair with up to four devices (three via Bluetooth and one via the 2.4GHz nano receiver) and includes on-board storage for the nano receiver for easy transport.

Advantages

The keyboard combines Bluetooth and RF wireless modes for flexible connection options and quick switching between paired devices. Scissor-switch keycaps with a 1.5 mm actuation point deliver a consistent tactile response and reduced key chatter, while the low-profile chocolate-style keycaps support comfortable typing during extended use. A rechargeable battery charged via USB-C reaches full charge in about 2.5 hours, and the compact footprint saves desk space while allowing a close mouse position.

How to use

Charge the keyboard using the supplied USB-C cable until the battery is full (about 2.5 hours). To connect via the 2.4GHz nano receiver, insert the receiver into a USB port on the host device; store the receiver in its on-board compartment when not in use. To pair via Bluetooth, enable Bluetooth on the target device and follow the keyboard’s pairing procedure to add up to three Bluetooth devices. Switch between paired devices using the keyboard’s device selection method. The keyboard supports layout swapping for different operating systems, so select the appropriate layout for Windows, Mac, iOS or Android as needed.

Usage recommendations

For reliable performance, keep the nano receiver unobstructed and within typical wireless range of the keyboard. Charge the keyboard regularly to maintain connectivity and replace long periods of inactivity with a short charge cycle before use. When using multiple paired devices, label or note the pairing order to ease switching between devices and select the OS layout that matches the active device for correct key mapping.
