Keychron B1 Pro Ultra-Slim Wireless Keyboard

The B1 Pro is particularly useful if your workday involves more than one computer. You can pair three devices through Bluetooth and connect another using the dedicated 2.4GHz receiver.

For example, you could use Bluetooth with a MacBook, Windows laptop and tablet, while keeping the USB receiver connected to your desktop PC. Switch between supported connections using the keyboard's controls.

This is more convenient than repeatedly pairing a single-device keyboard, especially for hybrid workers and multi-computer setups.

The B1 Pro is not a mechanical keyboard. It uses low-profile scissor switches, similar in principle to those found in many laptop keyboards.

This gives it a different typing experience from Keychron's mechanical models.

Keychron B1 Pro	Typical mechanical keyboard
Low-profile scissor switches	Mechanical switches
Slim laptop-style typing	More varied key travel and feel
Lightweight ABS construction	Often heavier construction
425g	Depends on model
Compact office and travel focus	Typing, gaming or enthusiast focus

The B1 Pro is better suited to users who prefer short key travel, a slim design and portability rather than the feel or customisation options of mechanical switches.

Its gently concave keycaps help guide finger placement during everyday typing.

One of the B1 Pro's biggest advantages is how rarely it needs charging.

Keychron advertises up to 1,200 hours of wireless operation, equivalent to approximately eight months when used for five hours per day.

The integrated 800mAh rechargeable battery charges through USB-C in around 2.5 hours. You can continue typing while connected by cable, so a depleted battery does not necessarily interrupt your work.

Actual battery life depends on connection mode, usage and operating conditions.

The three connection modes serve different purposes:

• 2.4GHz wireless: Up to 1,000Hz polling with the included USB receiver, suitable for responsive desktop use.

• Bluetooth 5.2: Up to 90Hz polling, useful for laptops, tablets and multi-device switching.

• USB-C wired: Up to 1,000Hz polling while providing a reliable wired connection and charging.

For everyday office typing, Bluetooth is generally sufficient. The 2.4GHz connection is a useful alternative when you prefer lower input latency or a dedicated receiver.

The B1 Pro supports macOS, Windows, Linux, iOS and Android, making it useful across different operating systems.

Its Mac-oriented function and multimedia controls can be adapted for Windows through Keychron Launcher.

It also includes a dedicated emoji shortcut, using Fn + Shift on the supported layout.

For users who regularly work between an Apple laptop and Windows desktop, this cross-platform flexibility is one of the strongest reasons to choose the B1 Pro.

Pair it with suitable desktop accessories to create a cleaner workstation.
