Techniques for wire-free charging

A method, comprising:

• producing a coupler signal with a radio frequency (RF) coupler coupled to a contact stripe structure of a wire-free power source based on an incident signal in the wire-free power source, the incident signal comprising an RF signal generated by a device in contact with a charger pad of the wire-free power source;
• identifying that the coupler signal includes a target characteristic indicating interference by the RF signal with operation of the wire-free power source to charge the device with an RF detection circuit;
• and
• altering an operational parameter of the wire-free power source.

One or more computer-readable media to store instructions that when executed by a processor circuit causes the processor circuit to:

• receive a coupler signal generated by a radio frequency (RF) coupler coupled to a contact stripe structure of a charger pad of a wire-free power source based on an incident RF signal generated by a device in contact with the charger pad;
• identify that the coupler signal includes a target characteristic indicating interference by the RF signal with operation of the wire-free power source to charge the device;
• and
• alter an operational parameter of the wire-free power source based on the coupler signal including the target characteristic.
