Once upon a time, there were two friends from two different worlds: the Electric Vacuum Cleaner and the Electric Outlet. The Electric Vacuum Cleaner needed energy and wanted to get this energy from the Electric Outlet. However, there was a problem. The plug of the Electric Vacuum Cleaner did not fit the Electric Outlet. They were both produced in different standards and could not communicate directly with each other. In this case, a hero emerged: the Adapter.
