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;
• 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 configured to mate with the socket;
• and
• iii. each adaptor plug further configured to mate with a style of electrical wall socket;
• and
• c) a power converter module.

A universal adaptor for use with a rechargeable handheld communication device comprising a power module including:
