IMPORTANT: Make sure you connect your inverter only to a 12V power supply 

(ordinarily an automotive battery).

1. Remove the protective cover or cigarette lighter from the accessory outlet in the 

vehicle passenger compartment.

2. Push the 12 volt power plug firmly into the outlet.

ATTENTION: Failure to make the correct connections will result in blown fuses 

and permanent damage to the inverter.

3. The LED indicator lights should glow GREEN, verifying the inverter is 

receiving power.

4. Make sure the device to be operated is turned OFF.

5. Plug the device into the inverter’s AC outlet or USB port.

6. Turn the device on.

7. To disconnect, reverse the above procedure.

NOTE: If more than one device is to be powered, start one device at a time, to 

avoid a power surge and overloading the inverter. The surge load of each device 

should not exceed the inverter’s Continuous Operation wattage rate.

Your average automobile or marine battery at full charge will provide an ample 

power supply to the inverter for approximately 2 hours when the engine is off. 

The actual length of time the inverter will function depends on the age and 

condition of the battery and the power demand being placed by the device 

being operated with the inverter.

Before starting the engine after using the inverter with the engine off, turn OFF 

the device plugged into the inverter and disconnect the inverter plug from the 

12 volt accessory outlet. To maintain battery power, start the engine every 1 to 

2 hours and let it run for approximately 10 minutes to recharge the battery.

Although it is not necessary to disconnect the inverter when turning over the 

engine, it may briefly cease to operate as the battery voltage decreases. While 

the inverter draws very low amperage when not in use, unplug it to avoid 

battery drain.

There are two stages involved in transforming 12 volt DC (battery) power into 

120 volt AC (household voltage):

STAGE 1: The power inverter uses a DC to DC transformer, to increase the  

12 volt DC input voltage from the power source to 145 volt DC.

STAGE 2: The inverter then converts the 145 volt DC into 120 volt AC 

(household voltage) using advanced MOSFET transistors in a full bridge 

configuration. A “modified sine wave” waveform is generated by this conversion.
