: 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 inverters
Continuous Operation wattage rate.
If you are using the power inverter to operate a battery charger, monitor the
temperature of the battery charger for about 10 minutes. If the battery charger becomes
abnormally warm, disconnect it from the inverter immediately.

You can use an extension cord from the inverter to the device without significantly
decreasing the power being generated by the inverter. Use a 18 gauge (AWG) (1.75mm

)
extension cord. For best operating results, the extension cord should be no longer than 50 feet
(15 meters).
Using the Inverter to operate a TV or Audio device:
The inverter is shielded and filtered to minimize signal interference. Despite this, some interference
may occur with your television picture, especially with weak signals. Below are some suggestions
to try and improve reception.
Make sure the television antenna produces a clear signal under normal operating

conditions (i.e. at home plugged into a standard 120-volt AC wall outlet). Also, ensure that
the antenna cable is adequately shielded and of good quality.
Try altering the position of the inverter, antenna cables, and television power cord. Add

an extension cord from the inverter to the TV so as to isolate its power cord and antenna
cables from the 12-volt power source.
Try coiling the television power cord and the input cables running from the 12-volt power

Affix one or several “Ferrite Data Line Filters” to the television power cord. Ferrite Data

: You may hear a “buzzing” sound being emitted from inexpensive sound systems when
operated with the inverter. This is due to ineffective filters in the sound system’s power supply.
Unfortunately, this problem can only be resolved by purchasing a sound system with a higher
quality power supply or higher quality filter.

When operating a device that draws approximately 60 watts, your average automobile or marine
battery at full charge will provide an ample power supply to the inverter for approximately 3 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.
If you decide to use the inverter while the engine is off, we recommend you turn OFF the device
plugged into the inverter and disconnect the inverter’s plug from the 12-volt accessory outlet before
starting the engine. To maintain battery power, start the engine every 2 to 3 hours and let it run for
approximately 30 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, it should be unplugged to avoid battery drain.
