BEFORE USING YOUR POWER INVERTER2.
When you turn on a device or a tool that runs on a motor, the
device basically goes through two stages:
Start Up – Requiring an initial surge of power (commonly 1.
known as the “starting or peak load”).
Continuous Operation – Power consumption drops (commonly 2.
known as the “continuous load”).
The wattage (WATTS) or amperes (AMPS) can normally be found
stamped or printed on most devices and equipment, or in the
user’s manual. Otherwise, contact the manufacturer to nd out
• 2 •
whether the device you want to use is compatible with a modied
sine wave.
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x WATTS. In
general, the start up load of the device or power tool determines
whether your inverter has the capability to power it.
To calculate the continuous load: Continuous Load = AMPS x 120
(AC Voltage).
Always run a test to establish whether the inverter will
operate a particular piece of equipment or device. In the event of a
power overload, the inverter is designed to automatically shut down.
This safety feature prevents damaging the inverter while testing
devices and equipment within the wattage range of the inverter.
When using the vehicle’s 12 volt accessory port, this
inverter is designed to supply 60 to 70 watts when the vehicle is
not running. With the vehicle’s engine running, it can supply up to
100 watts. To use the full output, you must connect the inverter
directly to your battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings
for all vehicles. Some vehicles may allow the full output. If the
fuse blows when you switch on the device you are trying to use,
you have to either use a smaller device or you must connect the
inverter directly to the battery.
This inverter uses a nonsinusoidal waveform. Therefore
we do not recommend you use it to power the following devices:
Switch Mode Power Supplies1.
Linear Power Supplies2.
Class 2 Transformers3.
Line Filter Capacitors4.
Shaded Pole Motors5.
Fan Motors6.
Microwave Ovens7.
Fluorescent and High Intensity Lamps (with a Ballast)8.
Transformerless Battery Chargers9.
Doing so, may cause the device to run warmer or overheat.

CONNECTING INVERTER CABLES3.
The inverter and power source must be in the OFF mode.
Make sure you connect your inverter to a 12-volt
power supply only.
Inverter connection:
Locate the positive and negative plastic terminals located on the 1.
back of the inverter and remove the terminal caps completely.
Install the positive (red) cable ring lug onto the positive (red) 2.
terminal screw. Install the negative (black) cable ring lug onto
the negative (black) terminal screw. Tighten each terminal so
that the cable cannot come loose.
Connecting inverter cable to a vehicle (100 watts maximum):
Remove the cigarette lighter from its outlet.1.
Push the 12-volt power plug rmly into the outlet.2.
Connecting inverter cables to 12v battery or 12v power
source:
Keep hands, hair, clothing and jewelry clear of battery terminals.1.
Wear eye protection and clothing protection.2.
Connect the positive (red) inverter terminal cable to the 3.
power source positive (+) or battery terminal. Make sure the
connection is secure.
Connect the negative (black) inverter terminal cable to the 4.
power source negative (-) or battery terminal. Make sure the
connection is secure.
To disconnect the inverter, reverse the above steps.5.
NOTE: The internal speaker may make a brief “beep” when the
inverter is being connected to or disconnected from the 12-volt
power source.
Failure to make the correct connections will result in
blown fuses and permanent damage to the inverter.

wattage used by the device. To change the digital display,
press the Display button.
To disconnect, reverse the above procedure.6.
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 inverters
Continuous Operation wattage rate.
If there is a short circuit or power surge in the
device, will display and the alarm will sound. Press the ON/
OFF switch to turn off the alarm. If the displays after several
attempts, there is a short circuit or the device requires more
“starting” or “peak” load than the inverter is capable of providing.
NOTE: After two events the inverter will go into a mandatory 10
second cool down period before it will turn on again.
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.
NOTE: You can use an extension cord from the inverter to the
device without signicantly decreasing the power being generated
by the inverter. For best operating results, the extension cord
should be no longer than 50 feet.

Using the Inverter to Operate a TV or Audio Device:
The inverter is shielded and ltered 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 1.
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 2.
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 3.
running from the 12-volt power source to the inverter.
Afx one or several “Ferrite Data Line Filters” to the television 4.
power cord. Ferrite Data Line Filters can be purchased at
most electronic supply stores.
NOTE: You may hear a “buzzing” sound being emitted from
inexpensive sound systems when operated with the inverter. This
is due to ineffective lters 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 lter.
POWER SOURCE5.
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
before starting the engine. To maintain battery power, start the
engine every 2 to 3 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 briey cease to operate as the
battery voltage decreases. While the inverter draws very low
• 6 •
amperage when not in use, it should be unplugged to avoid
battery drain.

The inverter will automatically restart after the voltage drops
below 15.0-volts.
• – The continuous load demand from the device exceeds
the inverter’s wattage output.
• – The inverter is overheated and automatically turns off
for a period of 1 to 3 minutes to cool. Make sure the inverter is
well ventilated. It will automatically restart after it cools.
• – The vehicle’s battery voltage is less than 10.5-volts.
• – Short circuit, power surge or overload in the device.
IF THE INVERTER FUSE BLOWS7.
Your power inverter is tted with a fuse, which should not have
to be replaced under normal operating conditions. A blown fuse
is usually caused by reverse polarity or a short circuit within the
device or equipment being operated.If the fuse does blow:
1. Disconnect the device or equipment immediately.
2. Find the source of the problem, and repair it.
3. Install a new fuse, 15-amp. The fuse can be found on the end of
the plug on the inverter.
4. Do not tighten the fuse cap too tight; nger tight is sufcient.
