Abstract: A power supply device includes an electrical connector and a power interrupt system. The electrical connector is configured to facilitate electrically coupling an electronic device to a power source to at least one of charge and power the electronic device. The power interrupt system selectively couples the power source to the electrical connector. The power interrupt system is configured to (a) provide energy to the electrical connector in response to at least one of (i) a first user request and (ii) a determination that the electronic device is coupled to the electrical connector, and (b) limit the energy provided to the electrical connector at least one of (i) in response to a second user request, (ii) in response to a determination that the electronic device is decoupled from the electrical connector, and (iii) after a threshold elapsed time.

Abstract: A battery pack includes a housing, one or more battery cells disposed within the housing, a power interface including one or more connectors, the one or more connectors configured to engage with an interface of an external device to at least one of charge the one or more battery cells and provide power from the one or more battery cells to the external device, and switching circuit. The switching circuit includes a limited flow circuit and a bypass circuit arranged in parallel between, and at least selectively electrically coupling, the one or more battery cells and the power interface. The limited flow circuit includes a resistor configured to at least selectively limit a current flow between the one or more battery cells and the power interface. The bypass circuit includes a switch configured to selectively place the one or more battery cells in direct electrical communication with the power interface.

Abstract: A portable energy storage and power supply system includes a first housing member, a second housing member coupled to the first housing member, a gasket coupling the first housing member with the second housing member, a battery, and a connector assembly coupled to the battery. The first housing member and the second housing member define an internal space. The battery is disposed within the internal space and configured to store electrical power. The connector assembly includes a shield having an open end and a closed end, a grommet disposed around an outer surface of the shield, and a cap disposed over the closed end of the shield and coupled to the grommet. The grommet is configured to reduce moisture penetration into the internal space of the first housing member and the second housing member.

Abstract: An energy storage and power supply system includes a body having a first end and an opposing second end, a battery pack disposed within the body, a first connector disposed at the first end of the body and electrically coupled to the battery pack, the first connector including a male connector configured to receive electrical power to charge the battery pack, a second connector disposed at the opposing second end of the body and electrically coupled to the battery pack, the second connector including a female connector configured to provide a power output from the battery pack, and a collar slidably coupled to the opposing second end of the body and movable between an extended position and a retracted position. The collar is configured to engage with and thereby retain an accessory when selectively reoriented into the extended position.

Abstract: An energy and power supply device includes an energy storage unit configured to store electrical energy, an output coupled to the energy storage unit and configured to provide an output electrical current to a load, and a current limiting system configured to selectively limit the output electrical current according to a current protection profile.
