Yes, you can. If you’re wondering whether it’s safe or effective to plug your grounding sheet into a power strip or an extension cord, the answer is yes—as long as it’s a grounded (three-prong) outlet. Both power strips and extension cords with grounding conductors allow energy to travel through the earth wire, extending the reach of your grounding setup without compromising its benefits.
But there's more to know if you want to ensure maximum safety and effectiveness. Let’s explore how it works, what to avoid, and why checking your connection matters.
Why Grounding Sheets Work Through Power Strips
Grounding sheets, such as those featured in our Best Grounding Sheets of 2025 guide, connect you to the earth’s natural electric field via your outlet’s grounding system. That third prong—the round one—isn’t just decoration. It’s a direct line to the grounding rod outside your home.
As long as your extension cord or power strip is three-pronged and properly grounded, it can carry that earth connection the same way a wall outlet does. Grounding sheets don’t draw electricity; they simply channel the earth's neutral charge to your body.

Key Safety Tips for Using Extension Cords with Grounding Products
Using a power strip may be convenient, but make sure you're doing it right. Here’s what you should keep in mind:
Do:
-
Use only 3-prong grounded cords
-
Test your outlet first using a multimeter or continuity tester—learn how in How to Test a Grounding Mat with a Multimeter
-
Keep cords in good condition with no frayed wires or cracks
-
Plug directly into a wall outlet—not another extension or surge protector
Don’t:
-
Use 2-prong cords or adapters
-
Assume grounding is working without testing
-
Use broken or damaged cords
-
Overload the power strip with multiple high-voltage devices

How to Check If Your Setup Is Properly Grounded
Before lying down and expecting better sleep, it’s smart to confirm your outlet is grounded. Even if the strip or extension cord looks fine, testing is essential.
You can:
-
Use a continuity tester
-
Try a basic outlet tester (available at most hardware stores)
-
Or use a multimeter if you’re more tech-savvy

Benefits of Flexible Grounding Setups
One of the biggest perks of using an extension cord or power strip is flexibility. You don’t need to rearrange your entire bedroom to reach a wall outlet. Whether you’re sleeping, working at a desk, or meditating on the floor, an extension cord lets your grounding sheet follow you anywhere.

And yes, if you’re curious—grounding sheets do work even without direct skin contact, although skin contact is ideal.
What About Safety Concerns?
Concerned about electric shock or interference? It’s a fair question. Grounding sheets don’t use electricity, but if you have faulty wiring or a misused extension cord, risks can appear.
