Operation 
 
Equipment Power Usage 
It is important to use only products that draw less than the power rating of the power inverter.  Use of 
products greater than the rated power rating may either cause the protection circuitry of the power 
inverter to shut down or the fuse to blow.  Repeated use of excessive power draw can cause failure of 
the power inverter. 
How to calculate power usage.  Most products have a power rating on them such as 45 watts.  Others 
may be marked with their current draw, such as .9 amps.  To convert the current to watts multiply the 
current by 115.  (Example:  .9 amps x 115 = 104 watts)

Some products draw a high surge current to start up.  If the appliance does not operate and the 
inverter turns off, you may need a larger inverter.  Also, check that the battery and the 12 volt wiring 
to the inverter is large enough to handle the current draw and that the battery is fully charged. 
 
Important:  The power inverters may not operate some appliances designed to produce 
heat such as hair dryers, heaters, toasters and coffee makers.  Always check the power 
rating before using these kinds of products to be sure they do not exceed the power 
capability of the inverter. 
 
 
Battery Life 
Important:  The power inverter can draw lots of amps from your car’s battery when operating.  If you 
are using it for extended periods of time, you will want to operate your car occasionally to maintain 
the charge in your car’s battery.  In addition, the power inverter will also draw a small current, less 
than 0.1 amp, when turned off and not operating.  Therefore, it should be disconnected from your 
car’s battery if your vehicle will not be used for more than a day.  The following chart shows typical 
operation time for typical car batteries with the engine not running for various loads.  Check the size 
of your battery.
