Overview

The Arkidyn Plus NK622-D-2.0-HE is a wired numeric keypad built for laptops and compact keyboards that leave out the number pad. What sets it apart from a plain keypad is the pair of host connectors and the three USB 2.0 ports built into the body, so it adds digits and extra ports at the same time.
You can connect over either USB-C or USB-A, which means a MacBook or Surface Pro and a conventional desktop tower both work without a dongle in between. The layout is 18 keys with a white LED indicator that shows the Num Lock state at a glance.
Scissor switches keep the typing quiet, and the chassis sits at a 15-degree angle that keeps the wrist in a more natural position. It is aimed at people who spend long stretches entering figures, whether that is bookkeeping, spreadsheets, or numeric work while coding.

Connectivity & Compatibility

This is a wired USB keypad with no driver installation required. It works with Windows, macOS, Chrome OS, and Linux, and it is ready as soon as it is plugged in.

  • Both USB-C and USB-A plugs are built in, so the host port shape does not limit you
  • The three onboard USB 2.0 ports accept a mouse, flash drive, or similar peripherals directly
  • On macOS only the number keys work; function keys are not supported
  • Typical hosts are laptops without a number pad, Surface devices, iPads, and desktops
    The hub section runs at USB 2.0 speed. That suits keyboards, mice, and flash storage, but it is not the right choice if you expect fast transfers from high-speed drives.

Product Info

At a price in the low 2,000-yen range, it sits in the entry-to-mid tier, and the value comes from combining a keypad and a port expander in one unit rather than buying them separately. The 18-key layout, 15-degree tilt, and quiet scissor switches point to office and study work rather than competitive gaming.
The Num Lock indicator is a small but practical touch, since it removes the guesswork that causes mistyped figures when the mode is wrong.

Best Use Cases

  • Laptop users who enter figures all day for accounting or spreadsheets: the keypad adds the missing digits while the spare ports take a mouse or flash drive, cutting down on gear to carry.
  • Anyone whose desktop USB ports are already full: three ports sit right beside the keyboard, so you can tidy the cabling without adding a separate hub.
  • People typing late in a shared room: the quiet scissor action and angled body ease long sessions, though anyone chasing mechanical feel or gaming-grade response should look elsewhere.
