Harbor Freight Tools 38391 Operation, VDC Charging, Using the Jump-Start as a 12 VDC Power source

Note: The LED light will go on (when Switch is in the OFF position) to indicate a reverse polarity condition.

12 VDC Charging

Note: This system is equipped with a 12 VDC Cigarette Lighter Adapter so you can charge the Jump-Start from a vehicle or boat battery. This method of recharging will not charge the unit as fully as when using the 120 V~ charging method. Only use this method in an emergency situation, as this recharging method may shorten the life of the Jump-Start.

5.Take out your 12 VDC Cigarette Lighter Adapter (6). The adapter has a cigarette lighter plug in one end of the cord, and a round plug on the other end. Plug the round plug into the Recharging Receptacle (See Figure 3). Plug the cigarette plug into the vehicle or boat cigarette lighter receptacle.
