How to Use

STEP 1: Test Your Three-Prong Wall Outlet
Plug the Outlet Checker into the wall outlet or power strip that you'd like to test.

STEP 2: Two Amber Lights = Grounded
When the center and right lights are illuminated together, your outlet is properly grounded.

Other Light Combinations = Ungrounded and Unsafe
Try testing other outlets if the first one isn't grounded. If you don't have any grounded outlets in your home, then you will need to order an Earthing Ground Rod to use your Earthing product, or call an electrician to fix your outlets.

Please Note: If your wall outlets only have two prongs, then there is no Earth/ground present. In this case, you must use an Earthing Ground Rod or have an electrician come in and ground your outlets.

Materials & Care Instructions

Store your Earthing Outlet Checker in a safe place when it's not being used.

Grounding 101

What is grounding?

The earth beneath your feet provides you with food and water. It gives you a surface to sit, stand, walk, run, swim, climb, play, and build on. It also provides you with something very surprising - electrons. When you touch the ground, the electrons flow into you. This is called being “grounded.” Earthing® products connect you to the earth's electrons while you're inside sleeping, working, and relaxing. Connecting to the ground by using our products indoors is called ‘Earthing.’

Is grounding a new concept?

No, it's not. Throughout practically all of history, humans have walked barefoot on the Earth. They have sat and slept on conductive animal skins, and fashioned those skins into footwear. Living like this enabled our predecessors to absorb the Earth’s natural energy into their bodies at all times. Over time, as we've "advanced" as a society, we've disconnected ourselves more and more from touching the Earth. Today, everyone is chronically disconnected from ground and as a society, we largely live our lives indoors. At Earthing®, we're committed to spreading the message that we all need to reconnect. We encourage everyone to get outside and put their bare feet on the ground whenever possible. We've created products that allow you to be connected to the Earth while you're sleeping, working, and living your life indoors.

Why do I need Earthing products® if I can just go barefoot on the Earth?

Earthing® products are a convenient and safe way to ground yourself for more hours each day. Our ancestors walked barefoot on the earth, wrapped their feet in conductive leather, and slept on animal hides on the ground. Such practices were part of the ordinary way of life throughout history. Our ancestors were always grounded. This is the ideal, but no longer how we all live. We rarely go outside barefoot save for when we are at the beach. We wear insulated shoes and we sleep on elevated beds inside our insulated houses.

Can I be grounded too much?

No, it's impossible to be grounded too much. (You can definitely be UN-grounded too much though!)

How quickly will grounding work?

Your body is a good conductor of free electrons. We have seen that when people are grounded in experiments with Earthing® Patches placed on the bottom of their feet (simulating standing barefoot on the Earth), they sometimes feel a tingling sensation moving up the legs. We associate this with the movement of electrons from the Earth up into the body. People say they often feel the same sensation when walking barefoot along the wet sand at the beach. In our research, we have “clocked” the speed of this activity. It takes about 20 to 30 minutes to reach the upper body, such as your shoulder. A knee would be reached faster as it is closer to the grounded feet. The effects on the body can vary depending on the individual, the method of grounding, and the condition you're hoping to improve. While some people may start feeling the effects almost immediately, it might take a few days or weeks of regular grounding sessions for others to notice the effects of grounding.

Earthing good!

Thanks for the prompt delivery of our package.
My wife has neuropathic issues with her feet and ankles. She's 59 yrs old and can hardly walk. It would be great if I could get her in or near the water.
