Where enabled devices automatically charge when within range of a transmitter, Powercast’s contactless charging technology provides over-the-air power at a distance to multiple devices – no wires, charging mats or direct line of sight needed. A transmitter sends RF energy to Powercast’s Powerharvester® receiver embedded in a device, which converts it to direct current (DC) to directly power that device or recharge its batteries. Operating across a wide RF power (as low as -20 dBm) and frequency (10MHz to 6GHz) range, the Powerharvester receivers are designed to convert RF to DC with up to 80 percent efficiency.
Two long-range transmitters pair with the Powerharvester receivers to serve different markets. Powercast’s 120-foot-range Powercaster® transmitter was FCC- and ISED-approved in 2010 (FCC ID: YESTX91501, IC #: 8985A-TX91501) for commercial and industrial applications. Powercast’s smaller PowerSpot® transmitter for consumer electronics can be a standalone charger, or be built into other consumer products that then become “PowerSpots” able to charge multiple enabled devices around them. The goal is for consumers to simply place enabled items for recharging within range of a PowerSpot in their home or public places.
