Inspired by the classics

The SOEWIOU 8BitDo Retro 18 Mechanical Numpad M Edition is a 2-in-1 device that works as a PC numpad or a standalone calculator. It connects to Windows 10 (1903) and above or Android 9.0 and above via Bluetooth 5.0, 2.4G wireless, or wired USB. The dedicated Windows Calculator shortcut button switches modes instantly. Kailh Box White switches V2 on a hot-swappable PCB with n-key rollover suit typists who want mechanical feel in a compact form.

Companion to the 8BitDo Retro Mechanical Keyboard

The numpad adds 18 keys without occupying a full-size board footprint. Top-mount construction and dye-sub PBT keycaps (M Edition) match the aesthetic of the main keyboard. Three connection options let you pair with a desktop over 2.4G, a laptop over Bluetooth 5.0, or a tablet via USB cable. The nine-digit seven-segment LED display shows calculator output independently of the host device. Hot-swappable sockets allow switch changes without soldering.

160 use hours on a single charge

Battery life reaches 160 hours and recharges in 4 hours over the included USB cable. Wired operation continues while charging, so workflow is not interrupted. Kailh Box White switches V2 produce an audible click; the top-mount plate amplifies sound compared with gasket-mounted alternatives. No active cooling is present, so thermal output is negligible. The independent LED display draws minimal power and can be read in low light without backlight bleed.
