Abstract
A method and device for wireless power transfer is provided. The device includes a plurality of charging holders positioned adjacent to each other. The method includes generating a first magnetic field using a first transmit coil in a first charging holder. The method further includes generating a second magnetic field using a second transmit coil in a second charging holder positioned adjacent to the first charging holder. The method further includes magnetically coupling the first and second magnetic field to a receive coil of a portable electronic device, wherein magnetically coupling includes transferring power from the first and second magnetic field to the receive coil of the portable electronic device, the first magnetic field and the second magnetic field configured to have a synchronized phase.
