1. A system to provide charge to a portable electronic device under an Extended Power Profile (EPP), the system comprising:

  • a memory configured to comprise a program and a processor configured to execute the program, wherein the program enables the processor to;

    determine whether the portable electronic device can support wireless charging;

    if the portable electronic device can support wireless charging, determine whether the portable electronic device can support being charged under the EPP;

    if the portable electronic device can support being charged under the EPP, conduct a handshake with the portable electronic device;

    based on the handshake, provide a negotiated rate of charge under the EPP to the portable electronic device via a wireless charging module comprising a cooling mechanism;

    measure a temperature of a power storage unit of the portable electronic device to ensure a safe amount of charge is being delivered to the portable electronic device;

    compare the temperature to a temperature threshold;

    when the temperature exceeds the temperature threshold, incrementally reduce the negotiated rate of charge under the EPP until the temperature is below the temperature threshold;

    when the temperature exceeds the temperature threshold, activate the cooling mechanism so as to help reduce the temperature; and

    wherein the EPP is the Qi Standard power profile allowing a power transfer up to and including 15 watts.
