A voltage adapter system includes a voltage modifier to invert and regulate voltage. A primary female plug is mounted on the voltage modifier and is electrically coupled to the control actuator. The primary female plug is an electrical inlet. An electrical outlet is mounted on the voltage modifier and is electrically coupled to the control actuator. A pair of clamps is provided and each of the clamps is positionable on and electrically coupled to a pair of leads of a vehicle battery. A male plug is electrically coupled to the clamps. The male plug attached to the clamps is removably extended into and electrically coupled to the primary female plug to supply electricity to the voltage modifier from the vehicle battery. A plug from an electrically powered apparatus is extendable into the electrical outlet to receive electrical power from the voltage modifier.
