Operating tips

The total wattage of all items plugged into 

the Power Inverter must not use more than 

750 watts during continuous operation, 

otherwise the Inverter may overload.
If an alarm sound is heard, turn off the appliances 

and check the Troubleshooting Tips section 

to correct the issue before continuing.

Caution:

 Some rechargeable appliances may damage 

the Power Inverter or the appliance.  When first using a 

rechargeable device, check the inverter’s temperature 

for the first 10 minutes.  If it becomes abnormally 

hot, do not use this device with the Inverter.

Caution:

  It is recommended that the vehicle be 

running when you first connect the Power Inverter. 

Thereafter the engine can be on or off. If you run the 

Power Inverter with the engine off it is recommended 

that you start and run the engine every hour for at 

least 10 minutes to recharge the battery.  Doing this 

will help prevent any unexpected shutdown of the 

equipment.  This will also help ensure that there will 

be enough battery power to start the vehicle.

  Due to 

the risk of carbon monoxide inhalation, do not run 

the vehicle’s engine within an enclosed area.

You should not use your car battery to power 

the Inverter for extended periods of time with 

appliances requiring high continuous load 

levels. The battery may become drained to the 

point that it will not be able to start your car.

note:

 Deep cycle (marine and RV) batteries  can be 

charged more times than a car battery, and are a better 

choice for repeated use of the Power Inverter.  

 

Do not discharge your car battery more than 

10% of its total capacity, and deep cycle batteries 

more than a 50% discharged state.
