Most power cords and chargers in your home carry an electric field whenever they are plugged in, even when nothing is switched on. Two-prong chargers and unshielded cords running behind a desk or under a bed keep that field next to your body for hours a day.
The cords, power strips and chargers in this collection wrap their conductors in a grounded shield, or use a true grounded three-prong design, so the field is drained to ground instead of extending into the room. They work as intended only on a properly grounded outlet.
Curious how electric fields differ from the high-frequency noise on your wiring? Read our dirty electricity guide, or see what wireless chargers emit. Looking for earthing mat cords instead? See Grounding Cords.
