     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to  FIGS. 1 through 6  thereof, a new power supply device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral  10  will be described. 
     As best illustrated in  FIGS. 1 through 6 , the portable power supply assembly  10  generally comprises a housing  12  that has a top wall  14 , a bottom wall  16  and a peripheral wall  18  attached to and extending between the top wall  14  and the bottom wall  16 . The bottom wall  16  has a well  20  extending upwardly therein and the top wall  14  has a pair of electrical sockets  22  positioned thereon. The electrical sockets  22  may be electrically coupled to an external electronic device  24 . The external electronic device  24  may be a laptop computer, a smart phone or any device requiring electrical power. A plurality of feet  26  is coupled to the housing  12  and the feet  26  are positioned on the bottom wall  16 . The feet  26  engage a support surface  28 . 
     A cord  30  is positioned within the housing  12  and the cord  30  is electrically coupled to the electrical sockets  22 . The cord  30  has a distal end  32  with respect to the housing  12  and the distal end  32  has a male plug  34  electrically coupled thereto. The male plug  34  may be electrically coupled to a power source  36  to supply the external electrical device  24  with power. The power source  36  may be an electrical outlet. 
     A spool  38  may be positioned within the housing  12  and biased in a conventional manner to rotate in a retracting direction. The spool  38  is urgeable to rotate in a releasing direction and the cord  30  is coupled to and wrapped around the spool  38 . The cord  30  may be selectively drawn outwardly from the spool  38  such that the cord  30  extends outwardly from the peripheral wall  18  of the housing  12  when the spool  38  is urged to rotate in the releasing direction. The cord  30  is selectively retracted into the housing  12  when the spool  38  rotates in the retracting direction. A door  40  is hingedly coupled to the peripheral wall  18  of the housing  12 . The door  40  covers the cord  30  when the cord  30  is retracted into the housing  12 . 
     A power supply apparatus  42  is positioned within the housing  12  and the power supply apparatus  42  is electrically coupled to the electrical sockets  22 . The power supply apparatus  42  may be electrically coupled to the power source  36  to charge the power supply apparatus  42 . The power source  36  may provide power to the external electronic device  24  when the cord  40  cannot be electrically coupled to the power source  36 . A control circuit  44  is positioned within the housing  12  and the control circuit  44  is electrically coupled to the electrical sockets  22 . The control circuit  44  converts a DC voltage to an AC voltage. The control circuit  44  may comprise an inverter of any conventional design. 
     A battery  46  is removably positioned within the well  20  and the battery  46  is electrically coupled to the control circuit  44  when the battery  46  is positioned within the well  20 . The battery  46  may be a Lithium Ion battery or the like. An actuator  48  is coupled to the housing  12  and the actuator  48  is electrically coupled to the control circuit  44  to actuate and de-actuate the control circuit  44 . 
     A light emitter  50  is coupled to the housing  12  and the light emitter  50  is electrically coupled to the control circuit  44 . The light emitter  50  emits light when the battery  46  is charged. The light emitter  50  may comprise an LED or the like. A charger  52  is provided that may be electrically coupled to the power source  36 . The charger  52  may have the battery  46  electrically coupled thereto after the charger  52  is electrically coupled to the power source  36  such that the charger  52  charges the battery  46 . The charger  52  may be a battery charger of any conventional design. 
     In use, the charger  52  is electrically coupled to the power source  36  and the battery  46  is electrically coupled to the charger  52  until the battery  46  is fully charged. The battery  46  is removed from the charger  52  and placed within the well  20 . The housing  12  may be transported to a remote location. The external electronic device  24  is electrically coupled to one of the electrical sockets  22  to supply electrical power to the external electronic device  24 . The cord  30  is electrically coupled to the power source  36  when the housing  12  is not in a remote location. The cord  30  supplies electrical power to the electrical sockets  22  while the cord  30  is electrically coupled to the power source  36  thereby allowing the housing  12  to be utilized in the convention of a power strip. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure. 
     Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
