Outlet Grounding Tester

For the Earth Goddess — first, make sure the outlet is holding up its end of the bargain.

Every grounding practice begins at the wall. Plug this little tester into any standard US outlet and its indicator lights report whether the wiring is properly grounded — so your earthing mat or sheet connects to the real thing, not wishful thinking.

Check the bedroom before setting up grounding sheets, or tuck it in a travel bag to vet hotel outlets. Reliable, reusable, and refreshingly unambiguous.

Fits 110–125V AC three-prong US outlets · Indicator lights detect wiring faults and grounding issues · Compact, portable, and built to last.
