num lock keypad

Common connection options are wired USB (USB‑C or Micro USB), Bluetooth, and 2.4 GHz / RF wireless (including proprietary 2.4G dongles).

Many numeric keypads list compatibility with Windows and Android. Some corded USB‑C models also note compatibility with Mac OS X and multiple Windows versions.

Setup is typically plug‑and‑play: USB/dongle models usually work when plugged in with no drivers required, while Bluetooth models pair with your device and often include simple controls such as sleep and on/off.

Some keypads offer a calculator mode, a dedicated Windows Calculator shortcut, and a retro LED numeric display—allowing them to function as both a PC numpad and a standalone calculator.

Many numeric keypads are slim and compact for easy transport. Wireless models run on batteries and are designed to fit in a bag for on‑the‑road use.
