Our Better Earthing Adapter is designed to safely conduct earth not electricity in Australian and New Zealand powerpoints. The top two prongs of Better Earthing adapter are plastic, instead of metal like a normal plug, so no a/c current from your electricity mains can pass through. Our adapters work with the powerpoint turned off (see more below).
You can safely use your Better Earthing Adapter with an extension cord, power board or standard double adapter, provided that they conduct earth. The best way to test this is with a multimeter.
Every Better Earthing Adapter contains two inputs so you can connect two indoor earthing products or a product and a multimeter for testing.
Please note this adapter must be used together with a Better Earthing Lead / cord which has the primary safety resistor built in. We do not sell adapters separately on their own for DIY purposes. A note also that USA brand and other Chinese made cords from Amazon etc use a 4.7mm banana plug connection and usually do NOT fit our Adapters, which have 4mm sockets. If you have any questions, please contact us.
