Abstract
A battery charger device characterized by a pair of cigarette lighter plugs having their negative contacts coupled together by a conductor and having their positive contacts coupled together by a self-resetting circuit breaker. In use, one of the plugs is inserted into the cigarette lighter socket of a car having a discharged battery and the other plug is inserted into the cigarette lighter socket of another car having a good battery. If the discharged battery starts to draw current that is greater than a predetermined level the current flow is regulated by a rapid cycling on and off of the circuit breaker. When the current drawn by the discharged battery is less than the predetermined level the circuit breaker conducts current between the two batteries with only insignificant IR loss.
