IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS – This manual will show you how to use
your inverter safely and effectively. Please read, understand and follow these
instructions and precautions carefully, as this manual contains important safety
and operating instructions.
WARNING: The inverter’s output is 120V AC and can shock or electrocute, the
same as any ordinary household AC wall outlet.
WARNING: Pursuant to California Proposition 65, this product contains
chemicals known to the state of California to cause cancer and birth defects or
other reproductive harm. Wash hands after handling.
•Do not cover or obstruct the inverter’s vents.
•Use the inverter in a well-ventilated area.
•This inverter is not intended for use by children.
•Do not expose the inverter to rain or snow.
•Ensure that the inverter is located away from normal trafc areas.
•Use only accessories recommended or sold by the manufacturer.
•Do not operate the inverter with damaged or undersized wiring.
•Do not operate the inverter if it has received a sharp blow, been dropped or
otherwise damaged in any way; take it to a qualied service person.
•Do not disassemble the inverter; take it to a qualied service person when
service or repair is required. Incorrect reassembly may result in a risk of re or
electric shock.
•Make sure the inverter is not close to any potential source of ammable
fumes, gases or clothing.
•Do not place the inverter in areas, such as battery compartments or engine
compartments, where fumes or gases may accumulate.
•Disconnect both AC and DC power from the inverter before attempting any cleaning.
•DO NOT operate the inverter if you, the inverter, the device being operated
or any other surfaces that may come into contact with any power source are
wet. Water and many other liquids can conduct electricity, which may lead to
serious injury or death.
•Do not place the inverter in direct sunlight. The ideal air temperature for
operation is between 50° and 80°F.
•Only connect the power inverter to a 12 volt accessory outlet or 12 volt battery.
•Do not attempt to connect the inverter to any other power source, including an
AC power source.
•Do not modify the AC or USB receptacles in any way.
•Do not try extending or otherwise changing the 12 volt power cord attached to
your inverter.
•Incorrect operation of your inverter may result in damage and personal injury.
•This device does not include an internal Ground Fault Circuit Interrupter
(GFCI). For GFCI protection, use a Coleman Cable 02822 GFCI outlet.

PERSONAL SAFETY PRECAUTIONS
•Wear complete eye and protective clothing when working near lead-acid
batteries. Always have someone nearby for help.
•Remove all personal metal items from your body, such as rings, bracelets,
necklaces and watches. A lead-acid battery can produce a short circuit current
high enough to weld a ring to metal, causing a severe burn.
•Never smoke or allow a spark or ame in the vicinity of the battery or engine.

BEFORE USING YOUR INVERTER
•This inverter 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 deepcycle battery, due to their high reserve capacity. Automotive batteries are
recommended for only a short period of time of an hour or less.
•Do not use the inverter with a product that draws a higher wattage than the
converter can provide, as this may cause damage to the inverter and product.
When you turn on a device or a tool that runs on a motor, the device goes
through two stages:
1. Start Up – Requiring an initial surge of power (commonly known as the
“starting” 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.
• 6 •
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x wattage.
In general, the startup load of the device or power tool determines whether
your inverter has the capability to power it.
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 750 watt 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 vehicle 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.
IMPORTANT: This inverter uses a modied sine waveform (diagram A) which
is not quite the same as power company electricity (diagram B). For the
following devices, we strongly recommend that you use caution and check the
device’s manual to make sure it is compatible with modied sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line lter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers
Using the inverter with any of these devices may cause the device to run
warmer or overheat.

IMPORTANT: 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.
CONNECTING INVERTER CABLES
The inverter and power source must be in the OFF mode.
IMPORTANT: Make sure you connect your inverter to a 12 volt power supply only.
INVERTER CONNECTION:
1. Locate the positive and negative plastic terminals located on the back of
the inverter 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 INVERTER CABLE TO A VEHICLE (100 watts maximum):
1. Remove the cigarette lighter from its outlet.
2. Push the 12 volt power plug rmly into the outlet.
CONNECTING INVERTER 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) inverter terminal cable to the power source
positive (+) or battery terminal. Make sure the connection is secure.
4. Connect the negative (black) inverter terminal cable to the power source
negative (-) or battery terminal. Make sure the connection is secure.
5. To disconnect the inverter, reverse the above steps.
NOTE: The internal speaker may make a brief “beep” when the inverter is
being connected to or disconnected from the 12V power source.
CAUTION: Failure to make the correct connections will result in blown fuses
and permanent damage to the inverter.
