Abstract: An electrical apparatus system includes a tool battery used as a power source for an electrical tool, and an electrical apparatus having a battery-connecting portion configured to allow the tool battery to be electrically and mechanically connected thereto or disconnected therefrom. In a state in which the tool battery is electrically and mechanically connected to the battery-connecting portion of the electrical apparatus, the tool battery is exposed on a lower side of the electrical apparatus so as to support the electrical apparatus on an installation surface thereof as a base.

Abstract: It is an object of the invention to provide a technique for bringing a center of gravity of a battery-powered power tool closer to a working axis of a tool bit in the battery-powered power tool. The battery-powered power tool performs an operation by movement of a tool bit 119 in an axial direction of the tool bit. The power tool includes a battery 110, a motor 111 that is driven by power supply from the battery 110, a mechanical arrangement 113, 115, 117 that drives the tool bit 119 by rotative power transmitted from the motor 111, and a tool body 103 that houses the motor 111 and the mechanical arrangement 113, 115, 117 and has a front end region in which the tool bit 119 is disposed. A sum of weights of the motor 111 and the battery 110 is smaller than a weight of the mechanical arrangement 113, 115, 117.

Abstract: An air compressor may include a compressor unit and an external tank unit connectible with the compressor unit. The external tank unit may include an external tank and a battery. The battery may supply electric power to the compressor unit.

Abstract: A toolbox is configured to store at least one hand-held tool in a forward leaning position. A front end portion of a tool main body and a rear end potion of a handle are supported by a seat portion of the toolbox.

Abstract: A battery pack is provided with a plurality of battery modules; a pack main body that removably receives the plurality of battery modules; a movable member that prohibits the plurality of battery modules from being attached to and removed from the pack main body at a first position; at least one sensor that detects whether the movable member is located at the first position or not; and a controller that performs at least one predetermined processing based on detection by the at least one sensor.

Abstract: It is an object of the invention to provide a technique to further increase protection performance for a battery pack of power tool. A representative power tool may include a tool body to which a tool bit is coupled to perform a predetermined operation, a driving motor that is disposed within the tool body, a battery pack that supplies driving current to the driving motor, the battery pack being removably mounted to the tool body and placed on the outside of the tool body in an exposed state, and a protector that is removably mounted to the tool body to protect the battery pack. The protector may include a battery pack protection area that protects the battery pack mounted to the tool body when the protector is mounted to the tool body. The battery pack protection area is dosed on at least part of the outer surface of the battery pack with a clearance and prevents transmission of external force upon the battery pack protection area to the battery pack.

Abstract: An electrical equipment system may include a battery for an electrical power tool, an electrical equipment except for the electrical power tool, and an adapter that is capable of electrically and mechanically connecting the battery and the electrical equipment. The adapter has a battery side connecting portion that is capable of being detachably connected to the battery and an electrical equipment side connecting portion that is capable of being connected to the electrical equipment.
