Again we ask ourselves, “How do we know how much power we actually use?” Because you know we can’t trust those darn, meddling power companies. The Saver Clip is designed to sense the electromagnetic filed pulsing through your power wires.
When you use power, an output is emitted from the wires in the form of electromagnetism. The more power you use, the higher intensity of the field produced. Saver Clip measures these fields and interprets it as stats which are shown on its display. — Andrew Dobrow
