The Keychron B1 Pro is an ultra-slim wireless keyboard designed for portability and versatility. It supports multiple connection modes, including 2.4 GHz wireless, Bluetooth, and wired connections, catering to a variety of user preferences. The keyboard is equipped with ZMK customization, allowing users to connect to multiple devices—such as phones, tablets, PCs, and Macs—simultaneously using three Bluetooth connections and one dedicated 2.4GHz dongle. The B1 Pro boasts a rapid 1000 Hz polling rate for peak performance, particularly in gaming scenarios. Additionally, it offers long battery life, with up to 1,200 hours of continuous use, and can be operated even while charging.
This is a unique product as it is a paper-thin wireless battery-powered keyboard, which is often used for on-the-go office work, but from a premium manufacturer of mechanical keyboards, rather than an office hardware brand. The Keychron B1 Pro is listed at $39.00 and is available directly from Keychron. The product comes in two colors; Space Gray and Ivory White.
