Womier SK30 ワイヤレスメカニカルテンキー

This article covers the Womier SK30 wireless mechanical numpad in detail, including specs, connectivity and the practical pitfalls buyers run into.

Overview

The Womier SK30 is a 30-key wireless mechanical numpad supporting Bluetooth 5.0, 2.4GHz and USB-C wired connections.

Its 3000mAh battery allows long stretches of use without frequent charging, and it works with PCs, laptops, tablets and smartphones.

Position it as an upgrade from a cheap slim numpad rather than as a high-end custom board. Full POM linear switches on a gasket mount give a soft typing feel, switches are hot-swappable, and the PBT keycaps resist the shine that ABS caps develop over time.

The standout feature is the color multimedia display and metal knob in the top right. The display shows custom GIF images plus CapsLock status, connection mode and backlight settings, while the knob handles volume and mute.

How It Differs From an Ordinary Numpad

Most budget numpads use pantograph or membrane switches, a single wired connection, and no remapping. The SK30 separates itself on four points: mechanical switches, tri-mode connectivity, full remapping of all 30 keys, and hot-swap sockets.

The feature gap is real, but so is the trade-off: more height, more weight and more noise. If your actual requirement is "thin and quiet," a plain pantograph numpad answers that better.

The SK30 suits people willing to pay for feel and looks.

Compatibility Guide

Supported operating systems are Windows, macOS, iOS and Android, connecting via Bluetooth or the 2.4GHz receiver.

Because wired USB-C also works, you can fall back to a cable when pairing is flaky or when wireless is unavailable, such as in BIOS. That escape hatch is a genuine advantage over wireless-only numpads.

Dimensions are 12 x 10 x 3.5 cm.

The 12 cm width roughly matches the numpad section of a full-size keyboard, so parking it beside your board does not eat much mouse room. The 3.5 cm height, however, is distinctly mechanical, and it will sit taller than a low-profile keyboard.

Plan on a palm rest or a riser if the height mismatch bothers your wrist.

Hot-swap sockets accept both 3-pin and 5-pin switches with no soldering. If the POM linears do not suit you, tactiles or clickies drop right in — but budget for about 30 switches, which means three 10-packs.

On macOS and iOS, Windows-oriented layouts and shortcuts such as the calculator key may not behave identically. Configuration software in this price bracket is often Windows-only, so if remapping matters to you, confirm the software's OS support on the manufacturer's product page before buying.

Product Info

Key specs: 30 keys, Bluetooth 5.0 / 2.4GHz / USB-C connectivity, a 3000mAh battery, full POM linear hot-swappable switches, PBT keycaps, 16.8-million-color RGB backlighting, a gasket-mount structure, and 12 x 10 x 3.5 cm dimensions.

RGB effects are configurable through dedicated software.

As captured in June 2026, the price on Amazon.co.jp was ¥7,599; on Rakuten (Lien no Tsuhan) it was ¥10,551 as captured in August 2026.

Both are point-in-time figures that move with sales and stock. A gap of nearly ¥3,000 between stores for the same product makes comparison shopping worthwhile.

The eBay entry returned only a search listing with no concrete price, so do not treat it as a reference.

The Amazon rating is 3.8 out of 5 (76% positive) from 8 reviews as of June 2026.

To be blunt, 8 reviews is too small a sample. At that count, one defective unit swings the average outright.

Rather than reading the star rating as a verdict, decide based on whether the caveats below are acceptable to you.

Best Use Cases

• Accounting and data-entry work — all 30 keys remap freely and there is a calculator shortcut key. Simply relocating Tab and Enter to match your entry flow measurably cuts hand travel.
• TKL or 65% keyboard users who occasionally need digits — keep it off the desk and bring it out only when needed; wireless means no cable to manage.
• People building a desk aesthetic — RGB, custom GIF display and hot-swap in one small device is unusual at this price, and it adds character without replacing your keyboard.
• Anyone wanting a left-hand macro pad — full remapping makes it viable as a shortcut pad placed on the left side.

Things to Check Before Buying

It is mechanical, so it is not quiet. The gasket mount and linear switches make it softer than a cheap mechanical, but quietness is not the selling point.

For an open office or live calls, budget for silent linear switches or choose a pantograph numpad instead.

It is thicker and heavier than a slim numpad. A 3.5 cm height plus a 3000mAh cell is not commuter-friendly.

If you plan to carry it daily, consider the weight and the risk of keys being pressed inside a bag. Its real strength is being repositionable on the desk, not portable.

Battery life cannot be inferred from capacity. 3000mAh is generous, but running RGB and the color display continuously drains it fast.

Check whether the manufacturer's quoted runtime assumes backlight off or on. In practice, keeping lighting modest is the sensible compromise.

Assume the software is priced-accordingly. Remapping and RGB control depend on dedicated software, which at this tier may have limited localization or updates.

Choose it only if you would still be satisfied using the default layout without software.

Verify the listing details yourself. This article is based on Amazon listing information, but online product pages sometimes carry incorrect model numbers or manufacturer fields, and prices differ by thousands of yen between stores.

Before ordering, confirm the product images, title, key count (30) and connection modes match what is described here.

Remember the thin review base. With only 8 reviews, there is little accumulated data on durability or unit variance.

If post-purchase support matters, buy from a seller with clear return terms.

FAQ

Q. Does it work on a Mac? A.

macOS and iOS are listed as supported, so it functions as an input device. Whether the remapping software supports macOS is a separate question — check the product page if you plan to customize.

Q. How many switches do I need to swap them all?
A. Around 30, so three 10-packs. Both 3-pin and 5-pin switches fit.

Q. Should I use 2.4GHz or Bluetooth? A.

Use the 2.4GHz receiver for latency and stability; use Bluetooth to keep a USB port free or to switch between devices.

Wired USB-C remains available as a fallback.

Q. Can I put my own image on the display? A.

Yes, it supports custom GIF images, alongside CapsLock status, connection mode and backlight settings. Transfer method and supported image sizes depend on the bundled software.

Q. Where is it cheapest? A.

At capture time, ¥7,599 on Amazon.co.jp (June 2026) and ¥10,551 on Rakuten (August 2026).

Prices move a lot, so check current listings before buying.
