1. A new and improved system for providing a predetermined amount of electrical power in response to a deposited coin comprising, in combination:

  • a mounting post secured to the ground;

    an input head secured at the upper extent of the mounting post, the input head including a plurality of slots for the receipt of coins to be used for the electrical usage to be provided and a door secured thereto and openable with a key for collecting coins therefrom;

    a plurality of readouts coupled to the input head to indicate the amount of coins deposited, the time of electrical usage remaining for the deposited coins and a selected voltage, and a switch for selection of 110 voltage or 220 voltage;

    an output module located on the post beneath the input head, the output module including a pair of electrical receptacles, the first electrical receptacle rated at 110 volts and having three wires for the receipt of a 110 volt plug with two prongs and a grounding component and the second electrical receptacle rated up to 220 volts and having three wires for the receipt of either a 220 volt plug with a grounding component and a horizontal and a vertical leg, or a 110 volt plug with a grounding component and two vertical legs; and

    a microprocessor responsive to the inserted coins for illuminating the readouts for indicating time, money, and voltage, as well as, an output device formed of three power delivery switches coupled to the output module and coupleable to an external source of electrical power for supplying electrical power to the electrical receptacles at the selected voltage for a time as determined by the amount of coins deposited.
