Claim 0:
1. A power transmitter for wireless power transfer, the power transmitter comprising:
a verification load;
a control and communications unit configured to:
provide power control signals to control a power level of a power signal configured for transmission to a power receiver,
provide a power request to an external power supply,
determine if the power signal at the verification load is compliant with the power request,
store a flag of non-compliance for the external power supply if the power signal is non-compliant with the power request,
determine if the flag of non-compliance was caused by a shutdown of the power transmitter or a brownout of the power transmitter if the power signal is non-compliant with the power request, and
continue to operate for wireless power transmission, if the power signal at the verification load is compliant with the power request;

an inverter circuit configured to receive an input direct current (DC) power from the external power supply and convert the input DC power to a power signal; and
a coil configured to transmit the power signal to the power receiver.
