NumberPad 21-Key HotSwappable Numpad - Compact Bluetooth/2.4G/USB

In this review the NumberPad 21-Key hot-swappable numpad is examined for users who need a compact, flexible numeric keypad for office work, data entry, and creative setups. The bottom line: it is best for people who want a portable, attractive numeric pad with multiple wireless modes and a satisfying mechanical feel. The pad stands out for its trio of connection methods and the smooth Neptune switches, making it a practical add-on for laptops and desktops while offering long battery life and customizable RGB lighting.

Key Features

• Three connection modes: The pad supports Bluetooth 5.2, a 2.4 GHz wireless dongle and wired USB-A to C, so switching between devices is fast and reliable.
• Multi-device pairing: Users can pair up to three Bluetooth channels and switch between them with FN+1, FN+2 or FN+3, which simplifies working across a laptop, tablet and phone.
• Hot-swappable Neptune switches: TTC Neptune switches with 41gf actuation and 2.0 mm travel offer a smooth, stable feel that suits long numeric typing sessions.
• RGB and backlight control: Twenty-two lighting effects and five brightness levels let users adapt the aesthetic and see keys clearly in low light.
• Rechargeable battery: The built-in 800mAh battery recharges by USB-C and delivers multi-day use - roughly seven days with lighting and longer without.
• Durable keycaps: Five-sided sublimation PBT keycaps provide bright, oil-resistant legends and long-lasting color on the pink keyset.

Who It's For

The NumberPad is ideal for office professionals, accountants and anyone who regularly enters numbers on a laptop or tablet and wants a dedicated mechanical pad that stays in sync across several devices. It also suits creatives who like a compact, stylish accessory with RGB flair and a pleasant switch feel.

It is less appropriate for gamers who need a full macro suite or for users who require ultra-low-latency wired-only competitive performance; those users may prefer a larger keypad or a unit focused solely on wired operation and macro software.
