!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.
