Yunzii has launched the AL21 Wireless Aluminium Mechanical Numpad, a compact 20% layout companion for users who want dedicated number input without sacrificing desk space. Built with a premium CNC-machined aluminium case featuring a sandblasted finish and oil-free coating, the AL21 combines durability with a refined aesthetic. It offers tri-mode connectivity including Bluetooth, 2.4 GHz wireless, and wired USB, allowing seamless switching between up to five devices such as PCs, laptops, tablets, and smartphones.

A 1500mAh battery provides approximately 90 hours of use with RGB off or 10 hours with backlighting on after a 3-4 hour charge. The numpad includes a multifunction knob for volume, RGB brightness, or ESC key functions, and supports hot-swappable 3-pin and 5-pin mechanical switches for customizable typing feel without soldering. Full N-Key Rollover ensures accurate keystroke registration.

Customization is handled via a web-based driver for key remapping and RGB control. Available in multiple colors, the AL21 targets spreadsheet work, gaming, studying, and minimalist desk setups.
