Abstract: A reconfigurable battery pack power system with interchangeable accessories has at least one modular, portable, rechargeable battery module having a first side, the first side having a first contour and a mounting port and a power output port, and at least one accessory module configured to receive power from the battery module. The accessory module has a second side with a second contour that mates with the first contour on the battery module, and has a power coupling connector and a fastener. The accessory module is interchangeably mateable with the battery module with the first and second contours nested together, and with the power output port engaged with the power coupling connector and with the fastener engaged with the mounting port, so that the battery module and the accessory module form a single integrated and substantially rigid structure.

Abstract: A charging device includes a body having a rechargeable energy storage device and a housing, an interface pivotally coupled to the housing, the interface including a first conductor and a second conductor and configured to transmit power between the rechargeable energy storage device and a device connected to the interface, a first rigid post, a first pin, a first compressible element positioned to press the first pin against the first rigid post, a second rigid post, a second pin, and a second compressible element positioned to press the second pin against the second rigid post. The interface is configured to pivot about an axis defined by the first pin and the second pin.

Abstract: Charging devices, modular adapters, and circuits are provided. One charging device including a body including a rechargeable energy storage device and a housing. The housing includes at least one first coupling portion. The charging device further includes a modular adapter including a second coupling portion configured to be mated to the first coupling portion of the housing. When mated to the housing, the modular adapter is configured to be electrically connected to the rechargeable energy storage device. When the modular adapter is mated to the housing, the body and the modular adapter form a single integrated and substantially rigid structure.

Abstract: A positioning system for a solar panel includes a frame, a surface plate, an adjustable rail and a frame coupling. The surface plate is configured to secure the positioning system to a mounting surface and includes a connection for an axle. The axle links the surface plate with the frame coupling or with the adjustable rail. The frame coupling attaches to the frame and holds the frame in an operating position. A length of the adjustable rail may be increased or decreased for varying the angular orientation of the frame relative to the mounting surface. The frame is configured to be removable from the frame coupling without requiring the surface plate to be removed from the mounting surface.

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: A lantern lighting device includes a base portion defining a user interface, an upper portion coupled to the base portion and having an upper cover, an energy storage device disposed within at least one of the base portion and the upper cover, a first LED and a second LED coupled to the upper cover and configured to provide a first and a second light output, a divider coupled to the base portion and the upper cover, and a controller. The divider forms a partition between the first LED and the second LED that separates the first light output from the second light output. The controller selectively engages the first LED in a first operation mode to provide approximately 180 degrees of illumination or that engages both the first LED and the second LED in a second operation mode to provide approximately 360 degrees of illumination.
