This article covers パナソニック(Panasonic) OAタップ 接地15A抜け止め形 4コ口・グレー 5mコード付 マグネット付 WCH2454H (× 4) in detail.

Overview

The Panasonic OA Tap WCH2454H is a four-outlet power strip rated 15A / 125V / 1500W. Its defining traits are locking outlets, a 5m cord, and a magnet on the body that lets you mount it on a steel desk leg, a rack, or the side of a machine.

The short verdict: this is not a consumer strip chasing looks or USB charging. It is a work-oriented product for places where a plug must never come out on its own.

The spec sheet lists a release date of December 1, 2002, making it a long-running staple. You could call the design dated, but in the power-strip category, staying on sale for two decades is itself evidence of low failure rates and stable supply.

This listing is a four-pack, aimed at people fitting several desks or racks at once. If you only need one unit, it is clearly overkill — more on that below.

Compatibility Guide

Per the compatibility data, the input is a grounded 2P+E plug (NEMA 5-15P equivalent) and the four outlets are the matching grounded type (NEMA 5-15R equivalent). Assume it is meant for a wall outlet that actually provides a ground.

Older two-prong outlets without a ground pin will either not accept the plug or require an adapter, so check the wall outlet at the install location before buying.

Locking outlets typically work by inserting the plug and turning it roughly 90 degrees to hold it in place. That stops vibration or a snagged foot from pulling the plug out, but the feel differs from an ordinary strip, so frequent plugging and unplugging becomes a small chore.

The payoff is greatest for gear meant to stay powered continuously — NAS units, recorders, measurement instruments, shop dust collectors.

The 1500W limit is the total across all four outlets, not per outlet. Two high-draw appliances — a kettle, a heater, a heat gun — will blow past it easily.

Typical always-on IT gear (PC, monitors, router, NAS) usually totals a few hundred watts, leaving comfortable headroom.

Physically, the 5m cord is the differentiator. It reaches from a corner outlet to the far side of a desk.

Long cords should not be run tightly coiled, though, since coiling traps heat — leave any excess loosely gathered. The magnet grips steel desks, server racks, and metal benches, but not wood, aluminum extrusion, or plastic.

Confirm your mounting surface first.

On pricing: as captured on August 24, 2026, Amazon.co.jp listed it at ¥22,328 for the four-pack, or roughly ¥5,580 per unit.

The same figure was captured on July 15, 2026, suggesting a fairly stable price, but stock and sales move prices — check the product page for the current figure. The eBay entry is only a search link with no confirmed price, so it is not a useful reference.

Reviews stood at 5 ratings, 3.5 out of 5 stars (70% positive) as captured on July 15, 2026.

Five ratings is thin evidence, and judging by stars alone would be a mistake here; a multi-unit pack at this price simply attracts few reviewers. Panasonic's track record in wiring devices and the rated electrical specs are the more reliable basis for a decision.

Market position is mid-range. It costs far more than a generic strip, and that premium buys the locking outlets, the ground pin, the magnet, and the long cord.

How It Compares

Strips in this price range split into three camps. First, surge-protected models focused on shielding gear from spikes.

Second, USB PD models for charging phones and laptops from the strip itself. Third, wiring-device style strips like this one, built around locking, grounding, and mounting.

WCH2454H sits firmly in the third camp, and surge protection, switches, and USB ports are not part of its listed specification. It is not a do-everything unit.

If lightning protection matters where you live, pair it with a surge-protected device upstream or a UPS. On the other hand, very few strips combine locking outlets with magnetic mounting, so substitutes are genuinely hard to find.

How It Actually Gets Used

The first setting is under an office desk: stick it to the steel underside and the classic accident — kicking a floor-bound strip and dropping a PC offline — stops being possible. The second is a workshop, where 5m reaches a distant wall outlet and the locking outlets keep tool cords from cutting power when tugged.

The third is around racks and instruments, where always-on gear benefits most from a plug that stays put.

At home, behind a TV stand or under a study desk is realistic. The gray, utilitarian look is not something you want on display in a living room, so aesthetics-first buyers should look elsewhere.

Best Use Cases

  • Office and SOHO users tidying desk power — magnet-mount it under the desk and cut floor clutter. The four-pack suits kitting out several desks.
  • Workshop, DIY, and studio users — 5m removes outlet-location constraints, and locking outlets survive a snagged cord.
  • Anyone running always-on gear like a NAS or recorder — the longer something stays plugged in, the more the locking mechanism pays off.
  • Facility refreshes — four identical units make standardizing hardware across a site easy.

Things to Check Before Buying

Remember this is a four-pack. The ¥22,328 captured on August 24, 2026 covers four units, which is far too much for someone who needs one.

If a single-unit or two-unit listing of the same model exists, that is the sensible buy. Do not read this price as a per-unit street price, and verify the quantity marker (× 4) on the product page.

Locking outlets are not for everyone. The insert-and-turn action adds friction if you unplug often for cleaning or swap devices regularly, and some plug shapes seat less securely than others.

As with any strip, four bulky AC adapters side by side may also crowd each other.

Do not misread the grounding. The unit has a ground pin, but it does nothing if the wall outlet has no ground.

Appliances that use a screw-down ground wire — washing machines, microwaves — use a different arrangement entirely and should be grounded at the wall terminal.

No surge protection, switches, or USB. If you want lightning protection or per-outlet standby cutoff, this product will not deliver it; choose a surge-protected strip or a UPS instead.

Respect the 1500W total. Filling all four outlets with high-draw appliances is unsafe.

Heating devices can draw around 1000W each, so avoid running two at once, and do not daisy-chain strips — it makes the total load impossible to track.

Watch for listing mismatches. Manufacturer names, model numbers, ASINs, and images on shopping pages are linked automatically and occasionally pull in data from a different product.

Before ordering, confirm with your own eyes that the title, images, and quantity all say WCH2454H and four units — pack-size variants of the same model number often sit side by side.

Finally, keep the 2002 release date in mind. The design is mature and dependable, but there is no USB-C delivery and no power monitoring.

Old but sure is the character of this product.

FAQ

Q. Can ordinary plugs go into locking outlets? A.

Standard locking outlets accept a normal plug and then hold it once you rotate it. Inserting works fine; securing it requires the turn.

How well it seats varies by plug shape, so test with the device you plan to leave connected.

Q. How much can I connect in total? A.

Up to 1500W across all four outlets. A desktop PC, two monitors, a router, and a NAS generally fit with room to spare.

Heating appliances consume most of the budget on their own, so avoid running several together.

Q. Does it include surge protection? A.

The supplied specification does not list any. For lightning protection, consider a product that explicitly advertises surge suppression, or a UPS.

Q. Will the magnet stick anywhere? A.

Steel desks, server racks, and metal benches, yes. Wood, aluminum, and plastic surfaces, no.

Check your intended mounting surface in advance.

Q. I don't need four. Is a single unit available? A.

This article covers the four-pack. If single or smaller-quantity listings of the same model exist, they will cost less overall.

Check the quantity marker before ordering.

Q. Is it safe to use the 5m cord while coiled? A.

Tightly coiled cord carrying heavy load traps heat. Gather excess loosely so it can shed heat rather than binding it into a tight bundle.
