An electrical charging system including an electrical charger assembly with a charger base coupled to an electrical power source. There is a first male terminal member terminating in a first electrical contact with at least two curved external surfaces and one flat surface. There is a second male terminal member terminating in a second electrical contact with at least two curved external surfaces and one flat surface. There is a cavity formed between the first male terminal member and the second male terminal member having an opening between the first and second electrical contacts. The cavity is defined by the flat surface of the first male terminal member and the flat surface of the second male terminal member. The flat surface of the second male terminal member has a flared surface portion proximate the opening of the cavity and angled relative to the second axis.
