Abstract

An electronic device (10), such as a radiotelephone, is connectable to a variable-level power source (16). Circuitry of the electronic device (10) generates power-source control signals to select the power levels of the signal generated by the variable-level power source (16). When the electronic device (10) comprises a radiotelephone having a rechargeable battery pack carried therewith, the variable-level power source (16) is operative to recharge the battery cells (70) of the battery pack when the transmitter circuitry of the radiotelephone is not being operated. When the transmitter circuitry of the radiotelephone is being operated, the battery cells (70) of the battery pack are not recharged and the power level of the signal generated by the variable-level power source (16) is of a level to power the transceiver circuitry of the radiotelephone.
