A contactless power supply for charging at least one device using magnetic field resonance includes an AC power supply, at least one circuit, a charging surface and at least one indicator to indicate a charging priority relative to the charging surface according to magnetic field strength. Devices placed near a region of the charging surface indicated as having a high priority by the indicators will charge more rapidly than an external device placed near a region of the charging surface indicated by the indicators as having a lower charging priority. Indication of the charging priority regions on the charging surface may be indicated by differing materials, patterns, shapes or offsets. In addition, the contactless power supply may have more than one region of high charging priority. |
