A4WP is making the distinction between direct induction and magnetic resonant induction where the two coils are tuned to resonate at a set frequency.
I understand this has benefits for efficiency of energy transfer.
I'm curious about this statement: "A4WP, which specifies the use of magnetic resonance technology, is capable of simultaneous charging of multiples devices and the flexible positioning of devices and a charging platter."
How is this different than what WPC is doing?
