Abstract: A battery charger has a case with multiple receptacles where each receptacle is configured to receive a battery. A filter is mounted within the case wherein the filter connects to a power line and is configured to reduce electronic noise. One or more printed circuit boards (PCBs) are mounted within the case and are coupled to corresponding receptacles. The printed circuit boards supply electric current from the power line to charge the batteries and are coupled to an output section of the filter. The PCBs are arranged in parallel to each other. The filter is positioned adjacent to the power line within the case. The battery electrically connects to the PCB via the receptacle by sliding across guide rails on the case.

Abstract: A charger is provided with a housing comprising an intake port and an exhaust port. A battery interface is disposed on the housing and is configured to removably receive the battery pack. A charging circuit is disposed within the housing and is configured to supply charging power to a battery pack attached to the battery interface. A blower is provided for introducing air into the housing through the intake port and exhausting air from the housing through the exhaust port. The housing is configured to be mountable on a wall extending in a vertical direction. The exhaust port is located higher in the vertical direction than the intake port when the housing is mounted on the wall.

Abstract: In an electric power tool which houses a motor and a controller for controlling drive of the motor, the controller has a circuit board on which electric components are mounted and a heat radiation member which radiates heat of the electric components. The heat radiation member has a facing part which faces the circuit board in parallel to a board surface of the circuit board. The facing part is provided with steps by which a distance between the facing part and the board surface of the circuit board varies. Furthermore, the facing part of the heat radiation member is provided with a first facing part in which a relative distance with respect to the board surface of the circuit board is reduced.
