Jump starter

A jump starter comprising:

• a charger case that is sized, shaped and structured to be hand-held and to contain components designedly to provide a design selection of desired care of vehicle batteries;
• an AC input cord having electrical conveyance from an AC source to an AC-DC converter that is contained by the charger case;
• the AC-DC converter being an electrical transformer, rectifier and filter that is structured to convert AC line voltage to DC voltage required to operate a select battery-charger circuit that is contained by the charger case;
• an AC charger line in electrical communication from the AC-DC converter to a battery charger that is contained by the charger case;
• a DC input cord having electrical conveyance from a DC source to a DC-DC converter that is contained by the charger case;
• the DC-DC converter being a boost converter that is structured to convert DC input voltage to DC voltage required to operate a select battery-charger circuit;
• a DC charger line in electrical communication from the DC-DC converter to the battery charger;
• the battery charger being a regulator of charge voltage and current required to charge and then to maintain charge of a battery;
• a charging-indicator LED positioned externally on the charger case and having charging-indicator circuitry in electrical communication with the battery charger to cause the charging-indicator LED to indicate that a charge circuit is supplying normal charge to a battery;
• a charged-indicator LED positioned externally on the charger case and having uncharged-indicator control circuitry in electrical communication with the battery charger to cause the charged-indicator LED to indicate that a charged battery is charged and that a charging circuit is maintaining charge of the charged battery;
• function conveyance in electrical communication between the battery charger and a function-selector switch with which functions of DC output are selected;
• the function-selector switch having a first position that connects an output socket directly to an internal battery;
• an internal-battery line in electrical communication from the function-selector switch to the internal battery;
• the function-selector switch having a second position that connects the battery charger directly to a DC output socket;
• the DC output socket being connectable to DC accessories or, optionally, the DC output socket being connectable to an external battery to charge the external battery directly;
• jumper cables that are in electrical communication from poles of the internal battery to poles of an external battery;
• an output line in electrical communication from the internal battery to the function-selector switch for electrical output to the DC output socket;
• the charging-indicator LED being red and the charged-indicator LED being green;
• an external-battery line in electrical communication from the function-selector switch to the external battery;
• the jumper cables being connectable from poles of the internal battery to poles of an external battery;
• voltage of the internal battery is as high as the highest voltage of external batteries to be provided with electrical input from the jump starter;
• the charger case has a first-cable channel in a bottom wall of a first side and a second-cable channel in a bottom wall of a second side of the charger case;
• a first jumper cable in electrical communication from a first electrical pole is extended outwardly from the charger case at a relatively high portion of a front first side of the charger case;
• a second jumper cable in electrical communication from a second electrical pole is extended outwardly from the charger case at a high portion of a front second side of the charger case;
• in a non-use mode of the jump starter, the first jumper cable is routed first through the first-cable channel to a rear side and then routed to a relatively high portion of a first side of the charger case where a clamp connector positioned on a distal end of the first jumper cable is supportable by a nonconductive cleat-support member that is shielded by a first-side roof holster and first-side walls to deter contact by opposite clamp connectors and by extraneous objects;
• also in a non-use mode of the jump starter, the second jumper cable is routed first through the second-cable channel to a rear side and then routed to a relatively high portion of a second side of the charger case where a clamp connector positioned on a distal end of the second jumper cable is supportable by a nonconductive cleat-support member that is shielded by a second-side roof holster and second-side walls to deter contact by opposite clamp connectors and by extraneous objects;
• the first jumper cable and the second jumper cable have lengths that provide designedly tight connection between positions of extension from a front of the charger case and nonconductive cleat-support members to which clamp connectors on distal ends of the first jumper cable and the second jumper cable respectively are connected in non-use mode of the jump starter;
• the AC input cord and the DC input cord are extended through line orifices in respectively opposite sides of the charger case;
• the AC input cord and the DC input cord are wound onto wind-up spools on the respectively opposite sides of the charger case in non-use mode of the jump starter;
• and
• the charger case is waterproof and has a top handle.
