Product Description

The Yunzii AL21 is a compact wireless mechanical numpad suited for users who need versatile connectivity and customizable input in a small footprint. It fits well for professionals handling numeric data across multiple devices, hobbyists who swap switches, and users wanting a portable keypad with adjustable lighting and macro support. Its tri-mode connection and hot-swappable switches offer flexibility, while the built-in knob adds quick control options.

Key Features

Tri-mode connectivity (Bluetooth, 2.4GHz wireless, and wired USB-C) allows easy switching between up to five devices, supporting desktops, tablets, and smartphones.
1500mAh battery provides extended use, around 90 hours without backlight and 10 hours with RGB lighting active, reducing frequent charging.
Customizable RGB lighting with nearly 20 presets and macro programming enables tailored workflows and visual feedback.
Full N-Key Rollover (NKRO) ensures every keypress registers accurately, useful for fast data entry or gaming.

Build Quality

CNC-machined aluminum case with sandblasted finish offers durability and a premium feel.
Dye-sublimated PBT keycaps resist fading, maintaining legend clarity over time.
Gasket mount with sound foams cushions keystrokes, reducing vibration and hollow sounds for a quieter typing experience.

Typing Experience

Hot-swappable sockets support both 3-pin and 5-pin switches, allowing users to customize switch type and feel without soldering.
The included YUNZII Cocoa Cream V2 linear switches provide a smooth keystroke, but users can replace them to suit personal preferences.
The multifunction aluminum knob enables volume and RGB brightness control or acts as an ESC key, adding convenience without extra keys.

Compatibility and Software

Works across Windows, macOS, Linux, Android, and iOS without driver installation, simplifying setup on multiple platforms.
Software and web-based customization tools allow key remapping and macro recording, enhancing productivity and personalization.

Trade-offs

The compact 20% layout limits the number of keys to 19 plus the knob, which may not suit users needing a full numeric keypad or additional function keys.
Battery life with RGB lighting active is significantly shorter, requiring more frequent charging during heavy use of backlighting.
Switch options are limited to the included linear type unless replaced by the user, which may require additional investment and effort.
