Overview

The Arkidyn Plus NK622D-B-JPH is a standalone numeric keypad built for laptops that ship without a number pad. What sets it apart from the usual budget numpad is the connector setup: the body carries both a USB-C and a USB-A plug, so a MacBook, a Surface Pro, or an older desktop with only rectangular ports can all connect without a dongle in between.
The layout is an 18-key arrangement with a white LED indicator that shows Num Lock status at a glance. A 15-degree incline keeps the wrist at a more natural angle during long data-entry sessions, and the scissor-style switches are tuned for quiet, low-noise typing rather than loud mechanical feedback.
On top of the keypad itself, the unit integrates a three-port USB 2.0 hub. That means a mouse or a flash drive can plug directly into the keypad instead of reaching for the laptop chassis, which helps tidy up a cramped desk.

Connectivity & Compatibility

Setup is plug-and-play with no driver installation required. Connect through either the USB-C or the USB-A plug and the keypad is recognized immediately. Supported operating systems are Windows, Chrome OS, Linux, and macOS, covering the main desktop environments.
One caveat applies on macOS: only the numeric keys work, and the function keys are not supported. If you simply want to add number entry to a Mac, that is fine, but anyone who expects full function-key behavior should look elsewhere.
The built-in hub follows the USB 2.0 standard and offers three ports. It suits keyboards, mice, and flash drives rather than high-speed storage, so do not expect fast transfers from an external SSD through this keypad. It works equally well as an add-on for a numpad-less laptop, a Surface, an iPad, or a desktop that needs extra ports.

Product Info

Positioned as a practical entry-to-mid tier accessory, the NK622D-B-JPH combines a keypad and a USB hub in one body.Check the retailer's page for the latest price. Availability is centered on domestic online retail.
Quiet scissor switches, the 15-degree tilt, and the LED indicator cover the basics, while the dual USB-C/USB-A plugs and three-port hub add flexibility for small desks where one device has to do several jobs.

Best Use Cases

  • Laptop users who crunch spreadsheets or handle bookkeeping: the keypad adds number entry and frees a USB port for a mouse, so no separate hub is needed. Not for gamers chasing mechanical key feel.
  • People shuttling between home and office: the dual USB-C and USB-A plugs mean no adapter to carry when the host machine changes. Mac users who rely on function keys will find it limited.
  • Anyone tidying a messy desk: peripherals can be consolidated on the keypad side, simplifying cable runs. Not ideal if you regularly attach a fast external SSD, since the hub is USB 2.0.
