Grounding Patches and the Testers That Prove Your Setup Works
Two very different kinds of gear share this page. Patches are a speculative, targeted way to ground one sore spot. Testers are the boring, essential tools that prove any of your grounding actually works. If you only buy one thing off this page, buy a tester. It is the cheapest item and the one that keeps you honest.
Testers: Buy These First
This is the least glamorous $10 you can spend on grounding, and the most important. A grounding mat or sheet connected to an ungrounded outlet does nothing. These two tools settle whether your setup is real. The full walkthrough is on how to test your grounding.
Outlet tester (Klein RT110)
Price: $9.97 (verified August 2026)
Does: confirms your outlet is correctly wired with a real ground
Best for: everyone grounding through a wall outlet
Plug it in, read the lights against the legend. If it does not show a correctly wired ground, that outlet is useless for grounding and worth fixing anyway. The Klein RT110 is under ten dollars and is the cheapest honest thing you can buy in this entire category. If you also want the GFCI trip test, the Klein RT210 is about $14. Either one does the job. Every grounding household should own one.
Check current priceContinuity tester or basic multimeter
Price: often included in grounding kits; standalone multimeters from about $15
Does: confirms the mat or sheet actually connects to ground
Best for: verifying gear on day one and retesting sheets over time
Hooga sells a purpose-built continuity tester for exactly this, and the Earthing Universal Mat Kit bundles an outlet checker. If yours did not, a $15 multimeter set to ohms tells you whether the conductive surface connects to ground with low resistance. This is how you catch a washed-out sheet or a dead cord before you waste weeks grounding to nothing.
See the purpose-built grounding testerHooga sells direct and offers HSA/FSA checkout through TrueMed, which can mean paying with pre-tax dollars if you qualify. How that works, and when it is not worth it.
Grounding Patches: The Speculative One
Patches are sticky conductive gel pads you place on a specific spot, a sore knee or heel, and wire to ground. The idea is targeted contact on the area that hurts. Be honest with yourself here: this is the most anecdotal use of grounding, with the least research behind it. Treat it as an experiment on one body part, not a treatment.
Earthing brand patches (Clint Ober / Earthing.com)
Price: $29.99 for 90, $59.99 for 180, $119.99 for 360 (verified August 2026)
Includes: the gel patches only. Accessories are not included
You also need: a grounding cord and an outlet tester, bought separately
Best for: people already grounding with this brand's gear who want the original patches
Correction, August 2026: this card used to describe a "Ground Therapy Patch Kit" at around $79 that bundled patches, cords, an outlet checker and Ober's book, and we recommended it partly because that bundled tester was a point in its favor. That product is gone. Earthing.com now lists patches only as refill packs, labelled "Accessories Not Included," at the prices above. So the one advantage we gave this card no longer exists, and the price we published was roughly two and a half times the real one.
What is left is a straightforward gel patch at about 33 cents each. That is a fair price and they are well made. But you are now buying patches the same way you would buy the generic ones below, minus a cord, minus a tester, from the brand that charges the most for everything else. If you already own a cord and a tester, buy on price.
Check current priceThis link goes straight to Earthing.com and we earn nothing if you buy from it. Earthing does not sell these refill packs through the Amazon storefront we can earn on, and we would rather send you to the right product than to a paying one that is not it.
Generic conductive gel patches
Price: about $27 for a 10-pack that includes a cord and adapter (verified August 2026)
Includes: reusable adhesive gel pads, a grounding cord, and a wall adapter
Best for: a cheap first try, because this is the version that comes with the cord
Worth knowing: the generic packs now commonly bundle the cord and adapter that the brand-name refills above leave out. Fewer patches for similar money, but you can actually use them out of the box. If you are trying patches for the first time and do not already own a cord, start here.
Just remember the patches are only as good as the ground they connect to. A patch wired to an ungrounded outlet is a sticker.
Check current priceHonest Priority Order
If you are shopping this whole niche for the first time: outlet tester first ($10), then a $25 mat, then, only if the mat earns it, a sheet. Patches are a later, optional experiment. Spend the least until grounding proves it does something for you, because the evidence has not proven it does something for everyone.
