1. A method for wireless transmission of power to a cordless power tool, comprising:

  • establishing, by a transmitter that is coupled to at least two antennas for transmitting power transmission waves to a plurality of cordless power tools, a connection with a power source that is used to charge a battery of the transmitter;

    determining, by the transmitter, whether the battery has a charge level that is above a threshold charge level;

    in accordance with determining that the battery has the charge level that is above the threshold charge level, identifying, by a communication component of the transmitter that is distinct from the at least two antennas of the transmitter, a cordless power tool of the plurality of cordless power tools that requires wireless charging;

    receiving, by the communication component of the transmitter, information that identifies a power requirement of the cordless power tool and a location of a receiver that is coupled to the cordless power tool; and

    transmitting, by the transmitter, a plurality of power transmission waves through the at least two antennas in response to the received information, wherein the plurality of power transmission waves are transmitted so that the plurality of power transmission waves converges to form a pocket of energy in proximity to the location of the receiver.
