The company's technology uses FCC-approved transmitters and receivers for over-the-air charging, transmitting a radio frequency (RF) whose energy can be "harvested" to power devices embedded with a small receiver. The Powerharvester receivers are designed to convert RF to DC with up to 80 percent efficiency, and the company's two long-range transmitters serve different markets. Powercast’s 80-foot-range Powercaster® transmitter was FCC- and ISED-approved in 2010 for commercial and industrial applications, while Powercast’s smaller PowerSpot® transmitter for consumer electronics can be a standalone charger or be built into other consumer products. The company has accumulated awards and created significant intellectual property (IP) surrounding RF-based wireless power, including 42 patents worldwide and 29 patents pending.
