Abstract: An improved jump starter system where at least one negative clamp/clip for the system is replaced with a magnet to allow a user to easily place the magnet on a dead metal area of the vehicle for an improved electrical connection. The improved jump starter preferably incorporates at least one grounding magnet to replace the conventional negative clamp. The grounding magnet provides for an alternative and improved way for making electrical connection by the negative/neutral cable. The improved jumper system is particularly idea for use in the automotive industry where a jump start system is used where the vehicle battery is depleted, as the improved jump starter system uses a magnet connection which improves the success for an engine start by providing a solid connection and closing the circuit between the jump starter and the vehicle battery.

Abstract: An electric vehicle (EV) to EV battery charger is provided, where a source EV provides electrical charge to a recipient EV to recharge the recipient EV's battery, without requiring a connection to a grid line. The battery charger includes an input port configured to couple to an electrical port of a source electric vehicle. A power control circuit of the battery charger receives a source power signal from the source electric vehicle through the input port. A converter circuit of the battery charger converts the source power signal to an output power signal according to power requirements of a recipient electric vehicle. The battery charger further includes an output port configured to couple to a charging port of a recipient electric vehicle. A microcontroller of the battery charger is configured to manage a transfer of the output power signal to the recipient electric vehicle through the output port.

Abstract: A charging system includes: an interface configured to removably and electrically couple to an external battery; a connector configured to removably and electrically couple to an on-board diagnostic (OBD) port of a vehicle; charge management circuitry electrically coupled to the interface and the connector; and a microcontroller unit (MCU) coupled to the charge management circuitry. The MCU is configured to execute computer readable program code for managing an output of current from the external battery to a vehicle battery of the vehicle through the electrical coupling of the connector and the OBD port. The charging system can be used to prevent a vehicle battery from becoming discharged during extended periods of storage.

Abstract: A sealed lead acid (SLA) battery jump starter system that charges and recharges via a single two-way USB, thus providing for a two-way power in/power out feature using a single USB port. The output is preferably provided with a ‘triple voltage select’ feature. In one non-limiting embodiment, the triple voltage select feature can allow for an output of either 5V, 12V or 20V. The system provides for higher power, a versatile design, and higher efficiency by integrating a USB charging circuit to recharge a lead acid battery in conjunction with drawing power from the lead acid battery to provide a preferred triple output switch mode selectable power. The system provides for a USB rechargeable charging circuit that can be capable of providing input low power to recharge lead acid batteries and also providing power out (preferably triple voltage and current choices) to recharge high output electronics.

Abstract: An auto safety jumper module to prevent accidental short circuits or wrong connections between a jump start system and a motor vehicle battery when jump starting such motor vehicle. The module can be fully automatic and capable of detecting when a motor vehicle battery is connected to it. The module, which can be integrated into or an external add-on to a jump start system, does not need an external sensing wire(s) to detect when alligator clamps of the jump start system are connected to a vehicle battery post or to detect when the alligator clamps are disconnected.
