1. A system for providing universal or improved compatibility and transfer of wireless power to mobile devices and batteries, comprising:

  • a charger, including a charger coil and one or more coil drivers, microcontroller units, or other output current and/or voltage controlling components,wherein the charger includes a circuit or other components that measures the current through and/or voltage across the charger coil,wherein the coil driver, microcontroller unit, or other output current and/or voltage controlling components receives a communication signal from a detection/demodulation or communication circuit, and makes appropriate adjustments to the charger coil drive circuitry to achieve a desired voltage, current or power at a receiver output, for using in powering or charging a mobile device and/or battery, andwherein the charger and the receiver initiate communication using a ping process which includes thatthe charger pings at a ping frequency associated with its charger type, andthe receiver determines the ping frequency of the charger and uses such information todetermine the charger type, wherein different charger types are associated with different charging protocols,select, from within the different charging protocols, a particular charging protocol to be used with the charger according to its charger type, andcommunicate with the charger, using the particular charging protocol, to power or charge the mobile device and/or battery, including communicating information to the charger for its use indetermining the receiver type, wherein different receiver types are associated with different charging protocols, andmaking the appropriate adjustments to the charger coil drive circuitry to achieve the desired voltage, current or power at the receiver output.
