2. BEFORE USING YOUR POWER CONVERTER
NOTE: This converter is designed to be used with a single battery,
up to group 31 (130 Ah or smaller). The recommended source of
power is a 12 volt deep-cycle battery, due to their high reserve
capacity. Automotive batteries are recommended for only a short
period of time of an hour or less.
• 3 •
NOTE: Do not use the converter with a product that draws a higher
wattage than the converter can provide, as this may cause damage
to the converter and product.
When you turn on a device or a tool that runs on a motor, the device
basically goes through two stages:
1. Start Up – Requiring an initial surge of power (commonly
known as the “starting load” or “peak load”).
2. Continuous Operation – Power consumption drops (commonly
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 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 converter 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 converter
will operate a particular piece of equipment or device. In the event
of a power overload, the converter is designed to automatically
shut down. This safety feature prevents damaging the converter
while testing devices and equipment within the wattage range of
the converter.
When using the vehicle’s 12 volt accessory port, this
converter 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 converter
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
converter directly to the battery.

Doing so may cause the device to run warmer or overheat.
3. FASTENING THE CONVERTER TO A FLAT SURFACE
For convenience, your converter can be fastened to a at
surface, horizontally or vertically. The area where the converter
is to be fastened must be dry, well ventilated and away from any
combustible material or fumes.
1. Turn off and disconnect the converter.
2. Place the back of the converter with the mounting bracket
against a secure and at surface.
3. Attach the converter to the at surface using corrosion-
resistant screws.
4. CONNECTING CONVERTER CABLES
The converter and power source must be in the OFF mode.
Make sure you connect your converter to a 12V
power supply only.
Converter connection:
1. Locate the positive and negative plastic terminals located on the
back of the converter and remove the terminal caps completely.
2. Install the positive (red) cable ring lug onto the positive (red)
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 converter cable to a vehicle (100 watts maximum):
1. Remove the cigarette lighter from its outlet.
2. Push the 12V power plug rmly into the outlet.
Connecting converter cables to 12V battery or 12V
power source:
1. Keep hands, hair, clothing and jewelry clear of battery terminals.
2. Wear eye protection and protective clothing.
3. Connect the positive (red) converter terminal cable to the
power source positive (+) or battery terminal. Make sure the
connection is secure.
4. Connect the negative (black) converter terminal cable to the
power source negative (-) or battery terminal. Make sure the
connection is secure.
5. To disconnect the converter, reverse the above steps.
NOTE: The internal speaker may make a brief “beep” when the
converter is being connected to or disconnected from the 12V
power source.
Failure to make the correct connections will result in
blown fuses and permanent damage to the converter.
5. OPERATING INSTRUCTIONS
1. Connect the converter (see “CONNECTING CONVERTER
CABLES” section).
2. Make sure the device to be operated is turned OFF.
3. Plug the device into the converter’s AC outlet.
4. Switch the converter’s ON/OFF switch to the ON position.
5. Turn the device on.
6. 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 converter.
The surge load of each device should not exceed the converter’s
Continuous Operation wattage rate.
If you are using the power converter 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 converter immediately.
• 6 •
NOTE: You can use an extension cord from the converter to the
device without signicantly decreasing the power being generated
by the converter. For best operating results, the extension cord
should be no longer than 50 feet.
Using the converter to operate a TV or audio device:
The converter 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.
1. Make sure the television antenna produces a clear signal
under normal operating conditions (i.e. at home plugged into a
standard 120V AC wall outlet). Also, ensure that the antenna
cable is adequately shielded and of good quality.
2. Try altering the position of the converter, antenna cables,
and television power cord. Add an extension cord from the
converter to the TV, to isolate its power cord and antenna
cables from the 12V power source.
3. Try coiling the television power cord and the input cables
running from the 12V power source to the converter.
4. Afx one or several “Ferrite Data Line Filters” to the television
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 converter.
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.
Using the USB Port:
The USB Port provides up to 2.1A at 5V DC.
1. Plug the device into the USB port.
2. Turn the USB device on.
3. Reverse these steps when nished using the USB port.
The converter draws power, even when the
switch is OFF. To avoid battery drain, disconnect
the converter when not in use.

6. POWER SOURCE
To get the best performance out of your converter, we recommend
that you use it with the vehicle’s engine running.
Your average automobile or marine battery at full charge will
provide an ample power supply to the converter for approximately
3 hours when the engine is off. The actual length of time the
converter will function depends on the age and condition of the
battery and the power demand being placed by the device being
operated with the converter.
If you decide to use the converter while the engine is off, we
recommend you turn OFF the device plugged into the converter
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 converter when
turning over the engine, it may briey cease to operate as the
battery voltage decreases. While the converter draws very low
amperage when not in use, it should be unplugged to avoid battery
drain.
7. LED INDICATOR AND SHUTDOWN PROTECTION
The LED glows GREEN when the switch is on, and under the
following conditions:
1. When the power input from the vehicle’s battery drops to
approximately 10 volts, low battery shutdown occurs and the
converter shuts off. The Green and Red LEDs are on, with a
buzzer. Solution: Recharge or Replace the battery.
2. When the power input from the vehicle’s battery exceeds 15
volts, high voltage overload protection occurs. The Green
LED is on, but the buzzer will not sound. Solution: Reduce the
voltage range to between 12 volts and 14 volts.
3. The continuous load demand from the equipment or device
being operated exceeds the continuous load rating of the
converter being used. The output pulses ON and OFF; the
Green LED is on. Solution: Use a higher capacity converter or
lower rated device.
• 8 •
4. The case temperature becomes hot (exceeds 145°F). The
Green and Red LEDs are on, with a buzzer. Solution: Allow
the converter to cool. Do not block the cooling slots or air
ow over and through the converter. Reduce the load on the
converter to the continuous rated output.
RESET: To reset after shutdown occurs:
1. Disconnect the converter from the 12V power source.
2. Check the source of the problem and correct.
3. Reconnect the converter to the 12V power source.
NOTE: If the red LED is lit and the green LED is not, see the
Troubleshooting section.
8. IF THE CONVERTER FUSE BLOWS
Your power converter 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 (25A). The fuse can be found on the back of
the converter.
Do not install a fuse with a higher amp rating than
the original fuse, as this may damage the converter and any
product you use with the converter. Make sure to correct the
cause of the blown fuse before using the converter again.
