Claim 0:
1. A power transmitter comprising:
a communicator circuit, wherein the communicator circuit is arranged to communicate with a power receiver;
a negotiator circuit, wherein the negotiator circuit is arranged to negotiate a guaranteed power level with the power receiver;
a determiner circuit,
wherein the determiner circuit is arranged to dynamically determine a maximum acceptable available power level in response to an operating parameter,
wherein the maximum acceptable available power level is a power level that can be provided by the power transmitter; and

a power controller circuit,
wherein the power controller circuit is arranged to control a power level of a power transfer signal in response to at least one power control message(s),
wherein the at least one power control message(s) is received from the power receiver,
wherein the power controller circuit is arranged to increase the power level above a minimum power level in response to the at least one power control message(s),
wherein the power controller circuit is arranged to reduce the power level regardless of the at least one power control message(s) in response to a detection that the power level exceeds the maximum acceptable available power level.
