Abstract: A mobile power source that has a battery pack including at least two battery cell assemblies each having frame that has a first support member and a second support member, each of the first and second support members including a plurality of cylindrical recesses that receive the plurality of battery cells to support the battery cells. Bus bars are coupled to the first support member via injection molding and each is configured to electrically connect to at least two battery cells. The bus bars each include an elongated conductive body that has a base and fingers extending laterally away from the base. Each of the fingers extend within a first plane, and the base extends within a second plane that is parallel to the first plane and offset therefrom.

Abstract: A portable charging station including a housing, a handle coupled to the housing and extending along a height axis of the portable charging station, a charging circuit disposed in the housing, a power tool battery pack interface electrically connected to the charging circuit, and a door including a hinge connected to the housing. The charging circuit includes a rechargeable battery. The power tool battery pack interface defines an insertion axis. The insertion axis extends along the height axis. The door is pivotable between an open position and a closed position. The door is intersected by the insertion axis in the closed position.

Abstract: A mobile power supply includes a frame, at least one battery pack supported by the frame, a clamp assembly coupled to the frame, and a handle removably attached to the frame. The handle has two elongate members that are spaced apart from one another and a cross-member extending between the two elongate members. The clamp assembly is configured to capture the cross-member with the handle in an operation configuration, release the cross-member to move the handle from operation configuration to a storage configuration, and capture the cross-member with the handle in the storage configuration.

Abstract: An electrical device capable of emitting or absorbs energy relative a surrounding environment. The electrical device includes a housing, an interior volume defined in the housing, an energy sensor at least partially exposed to the surrounding environment, a first material having a first absorptivity, and a second material having a second absorptivity lower than the first absorptivity. The first material is nearer to the surrounding environment than the second material is at an energy sensor reading below a threshold energy range, and the first material is farther from the surrounding environment than the second material is at an energy sensor reading above the threshold energy range.
