A contactless power supply is provided. The contactless power supply includes two or more primary coils for generating a region of cooperative magnetic flux generally therebetween. A portable device having a secondary coil can be positioned proximate this region of magnetic flux to receive wireless power from the contactless power supply. The spaced-apart primary coils can be wound in alternating directions about a common axis and driven in phase, or can be wound in a single direction about a common axis and driven approximately 180 degrees out of phase. The contactless power supply can include a plurality of primary coils in an adjustable array to accommodate multiple portable devices each with different secondary configurations and power consumption needs.
