An electrical plug assembly includes a secondary plug assembly which releasably mates with a rotatable default plug assembly. The default plug assembly is moveable between a storage position and a deployed position and includes a plurality of default prongs of a first physical configuration. A casing associated with the default plug assembly includes a recess for receiving the default plug assembly in the storage position. The distinct secondary plug assembly includes a main body and a plurality of secondary prongs of a second physical configuration extending from the front of the main body. The secondary plug assembly attaches to the default prongs to assume a mated position, such as by sliding the secondary plug assembly rearwardly over the default prongs. A suitable latch and catch arrangement is used to releasably secure the secondary plug assembly to the default plug assembly. Preferably, the only connection between the secondary plug assembly and the casing is via the default plug assembly. In the mated position, the secondary plug assembly rotates with the default prongs and the secondary prongs are in electrical contact with the default prongs. The recess in the casing is preferably of a size and shape to substantially contain the secondary plug assembly in the mated position when the default prongs are rotated to the storage position. Accordingly, the secondary plug assembly may remain installed over the default prongs even when the default prongs are moved to the storage position, thereby lessening the likelihood that the secondary plug assembly will be lost and making it more convenient for carrying with the secondary plug assembly attached.
