This adapter connects your grounding cords to the earth of a North American wall outlet. It has two ports, so one outlet can serve two grounding products.

It must be a three-prong outlet

This is the one thing to check before ordering. A three-prong outlet — the rounded third hole below the two slots — carries an earth conductor. The older two-prong outlet still found in some North American homes has no earth at all, and no adapter can add one. If your room only has two-prong outlets, an outdoor ground rod is the alternative.

What it does, and what it does not

  • Region: USA and North America, Type A/B outlets
  • Model KA-EPL, dual-port earth connection adapter
  • Two ports for two grounding cords at once
  • Connects to the earth contact only — passive, draws no electricity
  • Requires a correctly wired, earthed three-prong outlet

How to use it

  1. Check the outlet has three holes, then test it for a working earth.
  2. Push the adapter fully into the outlet.
  3. Snap one or two grounding cords into the ports.
  4. Connect each cord to its sheet, mat or pad.

My outlet has three holes — is that enough?

Not by itself. The third hole can be present with nothing wired to it, which a tester shows at once. How to test a wall socket covers what the lights mean.

Can I use a two-prong-to-three-prong cheater plug?

No. Those adapters do not create an earth; they only change the plug shape, so there would be nothing for the cord to connect to.

Does it draw power?

No. It contacts the earth path only, never the live or neutral slots.

Which sheets does it work with?

All of them — the cord fitting is standard across the range. See the plugs and adapters collection for other regions.

Product features

  • USA & North American Standard: designed for Type A/B sockets found across the USA, Canada, and other North American outlets.
  • Dual-Port Connectivity: features two integrated sockets, allowing you to ground two separate items (e.g., a sheet and a mat) simultaneously from a single wall point.
  • Safety Design: engages only the earth pin of the socket; the live/neutral slots are non-conductive plastic for stability, ensuring no contact with live electricity.
  • Standalone / Spare Adapter: our own-stock fitted sheets already ship with their region’s plug attached — this is for anyone who needs an extra or replacement USA adapter, or wants to connect an additional grounding product.

Materials and care

  • Construction: durable, standard electrical plastic housing with plastic dummy pins for the live/neutral slots.
  • Maintenance: wipe clean with a dry cloth. Keep dry — do not immerse in water.
  • Installation: we recommend testing your wall socket with a compatible USA socket tester prior to use to ensure a functional earth is present.

Common Questions about Grounding

What is earthing and how does it work?

Grounding, or earthing, means connecting to the earth contact of a wall socket. Our products do that through a cord with a built-in ≈91 kΩ ±1% current-limiting safety resistor — only the earth contact, never the live or neutral contacts. We won't promise what it will do for you.

Is it safe to plug a grounding product into a wall socket?

Grounding products connect only to the earth contact of your wall socket — never to the live or neutral contacts, which carry electricity. Every cord has a built-in ≈91 kΩ ±1% current-limiting safety resistor.

Does skin contact affect how grounding works?

Direct skin contact gives the most reliable connection. A thin natural layer such as cotton still conducts; a thick or synthetic one does not.

How do I know my outlet has a working earth connection?

Use a simple socket tester (we stock them in our range) — it plugs directly into your outlet and uses a row of indicator lights to confirm whether the Live, Neutral, and Earth connections are all present and correctly wired. A proper earth connection is required for indoor grounding products to work.

How long does it take to notice a difference from grounding?

People choose grounding bedding for their own reasons. Ask ten people why, and you'll hear ten answers. We won't promise what it will do for you.
