    Abstract: A jump starting apparatus for boosting or charging a depleted or discharged battery having a positive polarity battery terminal and a negative polarity battery terminal includes a rechargeable battery, an output port, a battery cable assembly, and a safety control system or circuit. The battery cable assembly includes a positive battery cable having a positive polarity battery terminal connector for connecting the jump starting apparatus to the positive polarity battery terminal of the depleted or discharged battery, a negative battery cable having a negative polarity battery terminal connector for connecting the jump starting apparatus to the negative polarity battery terminal of the depleted or discharged battery, and a plug connector coupled to the positive battery cable and the negative battery cable, the plug connector configured to plug into the output port, wherein the output port and the plug connector are dimensioned so that the plug connector will fit into the output port only in one specific orientation. The safety control system is configured for detecting when the jump starting apparatus is properly connected to the depleted or discharged battery and then switching on power from the rechargeable battery to the depleted or discharged battery only when the jump starting apparatus is properly connected to the depleted or discharged battery.
