Keychron B33-K9 Wireless Keyboard - Deep Black

Product Overview

The B33 is a wireless keyboard with a classic 80% TKL (Tenkeyless) layout, built for both versatility and comfort. Its silent typing and scissor mechanism deliver a smooth, quiet experience, while tri-mode connectivity—via 2.4 GHz, Bluetooth 5.2, and wired—ensures seamless use across multiple devices, whether you’re at home, in the office, or on the go.

Scissor Mechanism

The B33 scissor switch is equipped with a more innovative design than the traditional scissor mechanism. It is 59% taller than the standard ones, leading to a more accurate, stable and even quieter keystroke.

Silent Typing

Effortlessly switch between devices using Bluetooth 5.2, enabling smooth multitasking. Wired (USB-C) – for a stable, plug-and-play connection and charging at the same time.

Plug-and-Play Receiver

Continuous Usage

Our B33 keyboard is equipped with an 800mAh rechargeable battery, providing impressive long-lasting performance. With intelligent power management and efficient wireless connectivity, it can deliver up to 320 hours of continuous use on a single charge. You can rely on extended battery life—perfect for a truly wireless, uninterrupted experience.

Suitable For All Devices

The B33 has a system toggle to switch between Windows and macOS systems. And you can even configure different keymaps for both devices. Our Keychron Launcher web app is compatible with macOS, Windows, and Linux.

Ergonomic Support

The easily adjustable angles (6.5º/ 9º) bring out the best typing experience to provide long-lasting ergonomic support for your wrist. The slightly taller keycaps help prevent wobbling and reducing fatigue even during long typing sessions.

Convenient Shortcut Keys

The B33 is designed with user-friendly shortcut functionality, allowing you to easily switch between multimedia controls (like volume, play/pause, and brightness) and standard function keys (F1-F12). By pressing Fn + X + L for three seconds, you can seamlessly toggle between these two modes.
