Abstract: A charger includes a housing with an interface positioned in a front wall and configured to engage a battery pack. The interface includes charging terminals positioned between a first rail and a second rail, a first groove positioned between the first rail and a wall of the housing, and a second groove positioned between the second rail and the wall of the housing. The interface is in communication with an interior of the housing. A fan is coupled within the housing adjacent the interface, and an air passage member includes a hollow body that has a first end coupled to the fan and a second end spaced apart from the first end extending through another wall of the housing. The fan is operable to suck an air flow into the housing from outside the housing and guide the air flow through the air passage member to the interface.
