Electrical chargers for batteries and battery packs are described. The chargers include a recessed region having input ports or connectors for receiving power cords providing electrical power to the charger. The input ports or connectors ensure that only one of two ports or connectors is used for electrical connection to a power cord. Thus, due to the configuration of the input ports or connectors, two ports or connectors can not be used concurrently.
