1. A wireless power transfer system for computer peripherals, comprising:

  • a source magnetic resonator, integrated into a source station and connected to a power source and power and control circuitry;

    a device magnetic resonator, integrated into a computer peripheral;

    at least one additional device magnetic resonator, integrated into at least one additional computer peripheral;

    at least one additional source magnetic resonator integrated into the source station and connected to the power and control circuitry;

    wherein power is transferred non-radiatively from the source magnetic resonator to the device magnetic resonator, and the quality factors of the source and device resonators, Qs and Qd, satisfy the relationship, √

    {square root over (QsQd)}>

    100.
