Compact 20-key numpad for data entry

The Epomaker EK21 is a 20-key mechanical numpad built with a gasket-mounted structure and hot-swappable linear switches. An aluminum alloy knob adds tactile control for volume or custom functions. RGB backlighting and dye-sub PBT keycaps complete the compact 3.66 by 5.43 inch frame. It targets users who need a portable, programmable number pad separate from their main keyboard.

Suits spreadsheet users.

Accountants, analysts and gamers who want a dedicated numeric cluster with VIA programmability will benefit from the triple-mode connectivity and 1000 mAh battery. The single knob and 20-key layout limit complex macro layers, so users who rely on extensive multi-key shortcuts or a second full macro pad should look at larger programmable keypads instead.

VIA programmability decides fit

The decisive specification is the VIA-compatible QMK firmware that allows per-key remapping and macro creation through a web interface. If your workflow depends on custom key codes, layer switching or software-driven lighting profiles, the EK21 supports that natively. If you only need a standard plug-and-play numpad without remapping, the programmability adds complexity you will not use.

How often will the 1000mAh battery need recharging under daily wireless use?

With typical mixed Bluetooth and 2.4 GHz use the 1000mAh cell lasts several weeks; recharge via the wired USB connection when the indicator shows low power.
