Uniform wireless charging device

A wireless charging device, comprising:

• a resonator having coil windings that include an inner winding having an inner coupling and an outer winding having an outer coupling,
• wherein the wireless charging device is configured to be selectively operable in:
• a first mode of operation in which the inner coupling is connectable to a power source to power to the resonator;
• and
• a second mode of operation in which the outer coupling is connectable to the power source to power the resonator.

A wireless charging device, comprising:

• a resonator including coil windings that include an inner winding having an inner coupling and an outer winding having an outer coupling, the resonator configured to generate a magnetic field;
• and
• a selectively configured feed connectable to:
• (a) the inner coupling and (b) the outer coupling, the feed being configured to connect to a power source to power the resonator, wherein:
• in a first mode of operation, the inner coupling are configured to connect to the feed to connect the inner coupling to the power source;
• and
• in a second mode of operation, the outer coupling are configured to connect to the feed to the power source.
