1. A method of providing battery charge current to a portable electronic device having a rechargeable battery, the method comprising the steps of:
- providing a power adaptor which connects to a power supply and converts power from the power supply into a battery charge current;
providing a cable operative to deliver the battery charge current from the power adaptor to the portable electronic device to charge the rechargeable battery, the cable comprising at least one pair of electrical conductors for delivering the battery charge current; and
providing radio frequency (RF) signals induced onto the at least one pair of electrical conductors of the cable to an RF receiver input, the RF receiver input being configured to receive the RF signals induced onto the at least one pair of electrical conductors, wherein the cable serves as an antenna while simultaneously the at least one pair of electrical conductors delivers the battery charge current.
