IMPORTANT: CHARGE IMMEDIATELY AFTER PURCHASE
IMPORTANT: READ AND SAVE THIS SAFETY AND INSTRUCTION MANUAL.
IMPORTANT SAFETY INSTRUCTIONS1.
Before using your Power Inverter 750, read and understand this Owner’s
Manual.
Keep the inverter well ventilated in order to properly disperse heat gener-1.1
ated while it is in use. Make sure there are several inches of clearance
around the top and sides and do not block the slots of the inverter.
Make sure the inverter is not close to any potential source of ammable 1.2
fumes, gases or clothing.
Keep the inverter dry.1.3
DO NOT allow the inverter to come into contact with rain or moisture.1.4
DO NOT operate the inverter if you, the inverter, the device being operat-1.5
ed or any other surfaces that may come in contact with any power source
are wet. Water and many other liquids can conduct electricity, which may
lead to serious injury.
Do not place the inverter on or near heating vents, radiators or other1.6
sources of heat.
Do not place the inverter in direct sunlight. The ideal air temperature for1.7
operation is between 50° and 80°F.
Do not use the inverter near an open engine compartment.1.8
Only connect the power inverter to a 12-volt battery accessory outlet or1.9
12-volt battery. Make sure the AC plug and/or USB connection is tight.
Do not modify the AC or USB receptacle in any way.1.10
Use only 40-amp or 50-amp fuses. (Replaced by certied technician only: 1.11
1-800-SEARS-64.)
WARNING: Handling the cord on this product or cords associated with
accessories sold with this product, may expose you to lead, a chemical
known to the State of California to cause cancer and birth defects or other
reproductive harm. Wash hands after handling.

POWER INVERTER 750 PRODUCT FEATURES2.
BEFORE USING POWER INVERTER 7503.
It is important to know the continuous wattage of the device you plan to
use with the inverter. The Power Inverter 750 must be used with devices
drawing 750 watts or less. If the wattage is not marked on the device, an
estimate can be made by multiplying the AC input current (Amps) by the
AC voltage (110V).
Devices like TVs, fans and electric motors require additional power to start
(commonly known as the “starting or peak power”). The Power Inverter
750 can supply a momentary surge in wattage; however even devices
rated less than the maximum 750 watts can exceed the inverters surge
capability and cause an automatic overload shutdown.
Make sure the device you are using is compatible with a modied sine
wave inverter.

CONNECTING CABLE ASSEMBLY4.
Determine whether you’ll be using the battery clamps (750 watt out-
put maximum) or accessory plug (120 watt output maximum).
Make sure that there is no device plugged into inverter before making con-4.1
nection.
Unscrew the positive (red) and negative (black) plastic connector knobs4.2
from the studs on the back of the inverter.
Slip the red (positive) ring terminal of the 12V accessory plug over the red4.3
(positive) stud. Screw on the connector knob and tighten securely. Repeat
the same process for the black ring terminal.
Accessory Plug:4.4 Push the 12V accessory plug rmly into a 12V acces-
sory outlet.
Battery Clamps: Connect the red (positive) battery clamp to the posi-
tive (+) battery terminal. Connect the black (negative) battery clamp to
the negative (-) battery terminal, taking care to shield eyes, clothing and
hands from battery acid.
USING INVERTER5.
Determine the wattage of device being used. The Power inverter 750
must be used with devices drawing 750 watts or less when being
used with the Battery Clamps and 120 watts or less when using the
Accessory Plug.
Plug the device to be operated into either the AC outlet of the inverter or5.1
USB connector. NOTE: If using more than one device, the total combined
wattage of both devices must not exceed 750 watts.
Press and hold5.2 the ON/OFF button to turn the inverter ON. The VOLT-
AGE IN indicator will glow and the digital display will show the DC input
voltage.
Turn the device ON. To show AC VOLTAGE OUT, press the ON/OFF5.3
button once. Press the ON/OFF button once again to show total wattage
used by the device (POWER OUT). NOTE: If there is a short circuit or
power surge in the device, SC will display and an alarm will sound. Press
the ON/OFF button to turn off the alarm. If the SC displays after several
attempts, there is a short circuit or the device requires more surge power
than the inverter is capable of providing.
TO DISCONNECT THE INVERTER:5.4
Turn device OFF•
Press and hold• the ON/OFF button to turn the inverter OFF
Unplug the device from inverter•
If using the• Accessory Plug, unplug inverter from 12V DC accessory
outlet. If using the Battery Clamps, unclamp inverter from 12V battery.

DISPLAYS6.
LED Indicators6.1
The LED indicators identify the operating status of the inverter.
• VOLTAGE IN: DC voltage of the battery, vehicle electrical system or
power supply.
• VOLTAGE OUT: AC voltage supplied to device through the outlets.
• POWER OUT: AC power (wattage) supplied to device through the outlets.
Digital Display6.2
The values of the corresponding LED indicators will be shown in the digital
display.

If a problem develops during use, an audio alarm will sound, and one of
the codes shown below will display. To stop the alarm, press the ON/OFF
button.
BaD• – Inverter is not functional. Call Customer Service to trouble shoot
problem, anywhere in the U.S.A.
7 am to 4:30 pm Central Time, Monday through Friday, 1-800-SEARS-64
(1-800-732-7764).
H Ib• – Vehicle’s battery voltage is more than 15.5 volts. Inverter will auto-
matically restart after the voltage drops below 15.0 volts.
• H IP – The continuous load demand from the device exceeds 750 watts.
• HoT – Inverter is overheated and automatically turns off for a period of
1–3 minutes to cool. Make sure inverter is well ventilated. It will automati-
cally restart after it cools.
• Lo b – Vehicle’s battery voltage is less than 10.5 volts.
SC• – Short circuit, power surge or overload in the device.

OPERATING TIPS7.
A typical automobile or marine battery at full charge will provide an ample
power supply for the inverter. The actual length of time the inverter can be
operated depends on the age and condition of the battery and the amount
of power being drawn by the devices.
To extend operating time when using power from a car that’s not running,
turn OFF the device before starting the engine. Then run the engine peri-
odically for approximately 10 minutes to recharge the battery.
Unplug the inverter when not in use to avoid battery drain.
A “buzzing” sound emitted from inexpensive sound systems is the result of
ineffective lters in the sound system.
