In a contactless charging system charging energy is transferred across an inductive coupler to charge a battery (

21

) of a portable device, such as a two-way radio, cellular phone, paging device, or wireless communicator. The inductive coupler also provides a way for communicating at least one signal, such as to improve the charging process and the transfer of charging energy. Charging efficiency is improved by voltage regulation using feedback through the inductive coupler, or via a wireless RF link, and a controller (

11

) in-circuit with the primary side (

12

) of the inductive coupler. The controller (

11

) may communicate information signals via inductive coupling, or via a wireless RF link, for communicating with other devices such as smart cards and microphones or for control or data transfer.
