Abstract: An auxiliary electrical power system includes a housing that has a top wall, a bottom wall and a perimeter wall attached to and extends between the top and bottom walls. A battery for storing an electric charge is mounted within the housing. An inverter is mounted within the housing and is electrically coupled to the battery. A power cord is electrically coupled to the inverter and extends through the housing. The power cord has a distal end with respect to the housing. The distal end comprises a female plug configured to supply electricity to an electrically powered device from the battery when the electrically powered device is plugged into the female plug.
