     DETAILED DESCRIPTION OF THE INVENTION 
     With reference now to the drawings, and in particular to  FIGS. 1 through 5  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 5 , the wheelchair power supply system  10  generally comprises an electric wheelchair  12  that has an armrest  14 . A pouch  16  is provided and the pouch  16  is suspended from the armrest  14 . The pouch  16  has a plurality of apertures  18  extending into an interior of the pouch  16 . The pouch  16  has a bottom wall  20  and a perimeter wall  22  extending upwardly therefrom and the perimeter wall  22  has a distal edge  24  with respect to the bottom wall  20  defining an opening  26  into the pouch  16 . 
     The perimeter wall  22  has a front side  28 , a back side  30  and a first lateral side  32 . The back side  30  extends beyond the distal edge  24  with respect to the front side  28  and the first lateral side  32 . Additionally, the back side  30  is curled over onto itself to define a channel  34  and the channel  34  insertably receives the armrest  14 . The plurality of apertures  18  includes a first aperture  36  being positioned on the first lateral side  32 . Additionally, the plurality of apertures  18  includes a set of second apertures  38  being positioned on the front side  28 . 
     A power supply  40  is included and the power supply  40  is positioned in the pouch  16 . The power supply  40  has a charge port  42  and a plurality of outputs  44 . Each of the charge port  42  and the outputs  44  may comprise a usb port or the like. A charge cord  46  is provided and the charge cord  46  has a first plug  48  and a second plug  50 . The first plug  48  is selectively plugged into the charge port  42  and the second plug  50  is selectively plugged into a power source, such as a female electrical outlet, to charge the power supply  40 . 
     A first power cord  52  is provided and the first power cord  52  has a first plug  54  and a second plug  56 . The first plug  54  on the first power cord  52  is selectively plugged into a selected one of the outputs  44 . The second plug  56  on the first power cord  52  comprises an electrical plug that is matable to a power cord on the electric wheelchair  12 . Additionally, the second plug  56  on the first power cord  52  is selectively electrically coupled to the electric wheelchair  12 . In this way the power supply  40  serves as a backup power source for the electric wheelchair  12 . Additionally, each of the outputs  44  may have an electronic device electrically coupled thereto for charging. 
     A second power cord  58  is provided and the second power cord  58  has a first plug  60  and a second plug  62 . The first plug  60  on the second power cord  58  may be matable to the second plug  56  on the first power cord  52 . The second plug  62  on the second power cord  58  may comprise a cigarette lighter adapter or the like. The first power cord  52  and the second power cord  58  may be used in tandem to charge the electric wheelchair  12  from a cigarette lighter or the like. The power supply  40  comprises at least one rechargeable battery. The charge port  42  is aligned with the first aperture  36  when the power supply  40  is positioned in the pouch  16 . Each of the outputs  44  is aligned with an associated one of the second apertures  38  when the power supply  40  is positioned in the pouch  16 . 
     In use, the pouch  16  is suspended from the armrest  14  and the power supply  40  is positioned in the pouch  16 . The electric wheelchair  12  is selectively electrically coupled to the power supply  40  when the electric wheelchair  12  loses power. In this way the power supply  40  serves as a backup power source for the electric wheelchair  12 . Additionally, the electronic device may be charged with the power supply  40 . The second cord and the third cord are used together to facilitate the electric wheelchair  12  to be charged from a cigarette lighter in a vehicle or the like. 
     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, system 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.
