BEFORE USING YOUR POWER INVERTER3.
NOTE: This inverter is designed to be used with a single battery, up to group 31 type
and 130 Ah or smaller in size. Do not use with any larger battery type. Do not use
with multiple batteries connected in parallel.
NOTE: Do not use the inverter with a product that draws a higher wattage than the
inverter 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 basically goes
through two stages:
Start Up – Requiring an initial surge of power (commonly known as the1.
“starting or peak load”).
Continuous Operation – Power consumption drops (commonly known as2.
the “continuous load”).
• 4 •
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 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.
If a device does not operate properly when rst connected to the inverter, turn
the inverter ON, OFF, and ON again in quick succession. If this procedure is not
successful, it is likely that the inverter does not have the required capacity to operate
the device in question.
This inverter is designed to power 100 watt devices or less when
used with the vehicle 12 volt accessory port. To use the full 750 watt output you must
use the battery clips adapter and connect the inverter directly to the 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’s fuse blows when you switch on
the device you are trying to use, you have to either use a smaller device or use the
battery clips adapter and 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 Supplies;1.
Linear Power Supplies;2.
Class 2 Transformers;3.
Line Filter Capacitors;4.
Shaded Pole Motors;5.
Fan Motors;6.
Microwave Ovens;7.
Fluorescent and High Intensity Lamps (with a Ballast); and8.

Transformerless Battery Chargers.9.
Doing so, may cause the device to run warmer or overheat.
CONNECTING INVERTER CABLES4.
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:
Decide whether you want to use the 12 volt power plug (100 watts1.
maximum) or the battery clamps (full inverter capacity).
Locate the positive and negative plastic terminals located on the back of2.
the inverter and remove the terminal caps completely.
Install the positive (red) cable ring lug onto the positive (red) terminal screw.3.
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):
DC Outlet DC Plug
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:
NEGATIVE GROUNDED SYSTEM
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 power source3.
positive (+) or battery terminal. Make sure the connection is secure.
Connect the negative (black) inverter terminal cable to the power source4.
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.
OPERATING INSTRUCTIONS5.
Connect the inverter (see “CONNECTING INVERTER CABLES” section.1.
Make sure the device to be operated is turned OFF.2.
Plug the device into the inverter AC outlet.3.
Press and hold the ON/OFF switch to turn the inverter on. (The internal4.
speaker will make a brief “beep”. This is normal.) The Output Wattage LED
will glow and the digital display will show .
Turn the device on. The display will now show the total wattage used by the5.
device. To change the digital display, briey press the ON/OFF switch.
To disconnect, reverse the above procedure.6.
• 7 •
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.
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 USB Port
The USB port provides up to 500mA at 5V DC.
Plug the device into the USB port.1.
Turn the USB device on.2.
Reverse these steps when nished using the USB port.3.
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 under normal1.
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 television2.
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 the3.
12-volt power source to the inverter.
Afx one or several “Ferrite Data Line Filters” to the television power cord. 4.
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.
