Powermat uses electromagnetic induction to transfer energy between a transmitter (Powermat Charging Spot) and receiver (phone with embedded wireless charging or Powermat Ring). Inductive charging has been around for decades. It is commonly used for charging electric toothbrushes and other small electronics. Inductive charging capacity has since increased, and we are now able to charge smartphones and tablets. In the near future we will also be able to charge laptops. This technology is very efficient and safe compared to regular wires in traditional power cables.
