Universal adapter with interchangeable plugs

A universal adaptor apparatus for use with a handheld electronic device comprising:

• a) a case defining a socket, the socket having a plurality of first electrical contacts, the socket defining a first notch, a second notch, a first groove and a second groove, the first groove extending along a first side of the socket from the first notch, and the second groove extending along a second side of the socket from the second notch;
• b) a plurality of adaptor plugs,
• i. each adaptor plug having a plurality of recessed second electrical contacts each configured to communicate with a corresponding one of the first electrical contacts;
• ii. each adaptor plug having a first protrusion and a second protrusion;
• iii. each adaptor plug configured to mate with the socket by inserting the first and second protrusions into the first and second notches, respectively, and turning the adaptor plug to slidably engage the first and second protrusions with the first and second grooves, respectively;
• and
• iv. each adaptor plug further configured to mate with a style of electrical wall socket;
• and
• (c) a power converter module.

• and
• c) a power converter module, wherein the power converter module comprises a fuse, an input source, an electrical filter, a direct current (DC) transformer, a top switch feedback-loop, an output-rectified filter, a DC—DC converter, an output filter, an output and a voltage and current feedback controller.

A method of providing electrical power to a handheld electronic device comprising:

• a) providing an adaptor having a plurality of adaptor plugs, each plug of said plurality of adaptor plugs configured to couple to a different style of electrical wall outlet;
• b) selecting one plug of said plurality of adaptor plugs that is configured to mate with a desired electrical wall outlet style;
• and
• c) locking said one plug into said adaptor by inserting a protrusion on said one plug into a notched opening in said adaptor and turning said one plug so that said protrusion slidably engages a groove extending from said notched opening, thereby to configure said adaptor to couple to said desired electrical wall outlet and provide power to said handheld electronic device.
