A battery booster for jumpstarting a vehicle having an external battery. The battery booster may include a processor, a set of terminal connectors, a power supply, and a power-management circuit. The set of terminal connectors may be configured to couple with the external battery or an engine that is electrically coupled with the external battery. The power supply may include a lithium battery configured to supply a starting current to jump start an engine. The external battery may have a first nominal voltage, while the lithium battery may have a second nominal voltage that is greater than the first nominal voltage. The power-management circuit operatively coupled with the at least one processor, wherein the at least one processor is configured to transfer power selectively between the external battery and the power supply. The processor is configured to perform a pre-charge function and/or a back-feed function via the power-management circuit, which may employ a pulse width modulation (PWM) driver.

Charging connector

A battery charger and method is disclosed for detecting when a battery has a low state of health while simultaneously charging or maintaining the battery. A battery charger includes a processor; a non-transitory memory device; a power management device to receive an input power and to output a charging current; a pair of electrical conductors to electrically couple with a battery, and a display electrically coupled to the processor. The display being configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.

Describes is a battery booster for jumpstarting a vehicle having an external battery. The battery booster comprising a set of electrical conductors, a power supply configured to supply a starting current to jump start the vehicle via the set of electrical conductors, a boost switch positioned in-line between the power supply and a set of battery clamps on one of the set of electrical conductors; and at least one processor configured to output a control signal to close the boost switch as a function of one or more parameters of the power supply, the external battery, or the vehicle. The set of electrical conductors are configured to couple with the external battery or with an engine that is electrically coupled with the external battery via the set of battery clamps. The set of electrical conductors comprises a positive electrical conductor and a negative electrical conductor. The power supply comprises a plurality of lithium battery cells arranged to form a lithium battery having a positive terminal and a negative terminal.

A flashlight having a housing, a light-end assembly, and a user interface. The light-end assembly, which may be coupled to an end of the housing, may comprise a flexible light component having a proximal end and a distal end. A first plurality of light emitting diodes (LEDs) may be distributed on the first flexible light component between the proximal end and the distal end. The flexible light component may include a flexible, semi-rigid structure to maintain the flexible light component in a desired shape or position.

An interconnect device is disclosed for detecting whether an vehicle on-board diagnostics (OBD) data port includes a blocking diode or equivalent, that prevents back feeding of power through the OBD data port. If a diode is detected, the interconnect device alerts the user that the power cannot be back fed through the OBD II port connector. In such a condition, an alternate means is used to preserve the data mentioned above. If a diode is not detected by the interconnect device, the interconnect device displays this fact to the user. The interconnect device includes circuitry for detecting and displaying whether a diode is connected in series with a power pin of the OBD II port connector.
