Abstract

A battery charging apparatus for charging batteries of fixed voltage charge receiving batteries and flexible voltage charge receiving batteries. A wall receptacle charger outlet, an “all-in-one” vehicle or home charger, a hands-free docking station charger, a wall mountable USB charging strip and a holder for multiple charger receiving devices that includes a charger are disclosed.

Claims

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.

2. The receptacle assembly of claim 1 further comprising:

at least one single voltage receptacle provided on the cover plate that is adapted to provide a fixed voltage level for a fixed charge receiving device that may only be charged at a fixed voltage level.

3. The receptacle assembly of claim 2 wherein the at least one single voltage receptacle is provided with a fixed output AC/DC converter circuit that provides a fixed voltage to fixed charge receiving devices connected to the single voltage receptacle and is enclosed by the housing and cover plate.
