1. A wireless power receiver comprising:

  • at least one antenna configured to;

    receive radio frequency (RF) waves from a wireless power transmitter; and

    convert energy from the received RF waves into an alternating current;

    a rectifier coupled to the at least one antenna and configured to rectify the alternating current into a direct current; and

    a charger, coupled to and distinct from the rectifier, the charger configured to;

    receive the direct current from the rectifier; and

    control, via circuitry included in the charger, distribution of current using one or more of a plurality of conduction paths;

    (i) to a load, and (ii) to and from at least one storage element coupled with the charger,wherein;

    the circuitry included in the charger is configured to select the one or more of the plurality of conduction paths based at least in part on;

    a respective power requirement of the load, a respective power requirement of the at least one storage element, and the direct current; and

    the at least one storage element is separate and distinct from the load.
