1. A receptacle assembly for mounting in a wall for charging a selectable charge receiving device powered by a DC battery, the assembly comprising:
- a housing adapted to be secured to the wall;
a cover plate attached to the housing;
at least one multiple voltage output receptacle provided in the housing and adapted to provide a default level of voltage and a device selected predetermined level of voltage that is greater than the default level of voltage for charging the selectable charge receiving device;
wherein the housing and cover plate enclose;
a control circuit that communicates with the selectable charge receiving device that is adapted to be charged at the predetermined level of voltage and that provides a charging level signal;
a voltage switching circuit that receives the charging level signal;
a variable output DC/DC converter circuit controlled by the voltage switching circuit that is configured to provide the predetermined level of voltage to the selected charge receiving device; and
at least one single voltage receptacle is provided with a fixed output DC/DC converter circuit that provides a fixed voltage level to at least one fixed charge receiving device connected to the single voltage receptacle.
