Abstract: A portable power supply assembly includes a housing that has a pair of electrical sockets positioned thereon and the electrical sockets may be electrically coupled to an external electronic device. A cord is positioned within the housing and the cord is electrically coupled to the electrical sockets. The cord has a distal end with respect to the housing and the distal end has a male plug electrically coupled thereto. The male plug may be electrically coupled to a power source to supply the external electrical device with power. A power supply apparatus is positioned within the housing and the power supply apparatus is electrically coupled to the electrical sockets. The power supply apparatus may be electrically coupled to the power source wherein the power supply apparatus is charged. The power source may provide power to the external electronic device when the cord cannot be electrically coupled to the power source.
