ABSTRACT:
A booster apparatus is provided for applying electrical power to a device in which a power source having positive and negative terminals is disposed in a housing, with electrical cables extending from respective positive and negative or grounded terminals to exterior of the housing, with an electrical switch interposed in one of said electrical cables interior of the housing manually actuable from outside of the housing, with an electrical circuit operatively coupled to one of the cables and the electrical switch, whereby the electrical circuit effects automatic closing of an electrical switch upon imposition of a predetermined minimum voltage to the cables, and effects opening of the electrical switch upon the second cable having a voltage less than the predetermined minimum voltage, and with a voltage comparator and its associated circuitry to indicate a level of charge for the power source. Hence, the portion of the cables extending exteriorly of the housing are not live unless and until connected with a device having a voltage greater than a predetermined voltage, such as provided by a depleted automobile battery.
