Method and apparatus for providing supplemental power to an engine

A method for delivering supplemental power from a portable jump starter to an engine comprising the steps of:

• positioning said portable jump starter proximate the engine;
• temporarily manually connecting conductive leads from said portable jump starter to the electrical system of the engine;
• automatically selecting a voltage output of one or more system batteries housed in said portable jump starter and one or more system capacitors housed in said portable jump starter,
• verifying the polarity of the conductive leads;
• providing an alert if said polarity is incorrect;
• assessing the voltage level of said electrical system;
• applying power from said system batteries and said system capacitors to said electrical system;
• monitoring the current output of said system batteries and said system capacitors;
• measuring one or more voltage levels to determine one or more fault conditions;
• examining the current through a shunt cable;
• and
• electrically disconnecting said conductive leads from said electrical system when the engine starts.
