A4Tech Fstyler FBX55C Dual-Mode Bluetooth Wireless Keyboard

The A4Tech Fstyler FBX55C is a dual-mode wireless keyboard that lets you type over Bluetooth or a 2.4GHz connection and switch between up to 4 devices. If you move between a laptop, desktop, and other devices during the day, you can keep working on one keyboard instead of reaching for a different one each time.

It charges over USB Type-C and uses a 300mAh lithium battery, so there are no disposable batteries to replace. Built-in lighting and a choice of black or white make it a practical fit for a home desk or an office workspace.

If you are comparing an A4Tech keyboard for everyday typing, the FBX55C covers the essentials: flexible wireless connectivity, rechargeable power, and support for both Windows and Mac.

Key Features

• Dual connectivity (Bluetooth + 2.4GHz): Pair over Bluetooth for a receiver-free setup, or use 2.4GHz for a dedicated wireless link. You can choose whichever suits your device and workspace.
• Switch between up to 4 devices: Keep several devices paired and move between them without re-pairing each time, which saves time when you work across more than one screen.
• USB Type-C rechargeable battery: The 300mAh lithium battery recharges over a common USB Type-C cable, so you avoid buying replacement batteries and can use a charger you probably already own.
• Fast, responsive wireless performance: A4Tech describes this keyboard as ultra fast wireless, built for typing in the office and gaming sessions alike. The 125 Hz polling rate suits everyday work and general use.
• Built-in lighting: The keyboard includes lighting, which helps you see the keys in dim rooms or at night.
• Windows and Mac support: One keyboard works across both systems, which helps if your home or office setup mixes the two.
• Black or white finish: Pick the color that matches your desk and your other peripherals.
• Slim 437 x 133 x 18 mm body: The 18 mm height keeps the keyboard low-profile on the desk.
