YUNZII introduced the AL21, a compact digital numpad designed to expand typing setups without taking up much desk space. This device targets users who need dedicated number entry keys for spreadsheet work or gaming macros but prefer a standalone unit over a full-sized keyboard. The release targets users seeking compact input devices that provide a mechanical typing experience.
Compact aluminum numpad with tri-mode connectivity and hot-swappable switches
The AL21 features a rigid aluminum alloy body constructed through CNC machining, providing a sturdy base for the internal components. It supports tri-mode connectivity, allowing users to switch between wired USB, 2.4GHz wireless, and Bluetooth connections depending on their device and preference. The device features a dedicated layout for numbers and navigation keys to maintain a compact size.

Inside the chassis, the numpad utilizes a Gasket mount structure to isolate the PCB from the case, which helps reduce vibration noise. The switches are hot-swappable, meaning users can replace them without soldering. YUNZII pre-installs Snow Top Coffee V2 switches, which the source describes as having a linear feel and a 'stone-like' sound due to their PC top housing, POM stem, and nylon base construction. The keycaps are made of PBT material with dye-sublimation printing in the CHERRY height profile.
The device includes south-facing RGB LEDs to illuminate the keys without blocking the light from reaching the keycaps. A 1500mAh battery powers the unit, offering up to 90 hours of wireless battery life. The AL21 is available in pink, white, and black color options. YUNZII lists the price at 49.99 USD (around $49.99) for the global market.
