Running on conventional current, a Powercaster™ element generates a safe energy field designed to be a few millimeters or centimeters deep. A matching Powerharvester™ element entering the field captures energy and generates useful current, even if the elements are separated by open space or solid matter. That current can recharge a battery or directly power an electronic device.

At efficiencies nearing 90%, patented Powercast technology transfers power between compact components that fit inside products without adding bulk.
