Do not disassemble. This item has9.
no replaceable parts. If this product
is damaged and/or does not func-
tion properly, the entire unit must be
replaced.
Use the right inverter for the job10. .
Do not attempt to force a small in-
verter or attachment to do the work
of a larger industrial inverter. There
are certain applications for which
this inverter was designed. It will do
the job better and more safely at the
rate for which it was intended. Do not
modify this inverter and do not use
this inverter for a purpose for which it
was not intended.
Do not overload this device.11. This
device is designed for loads up to 80
Watts at 120 Volts AC only. Check
the wattage of any device before us-
ing this item to power it. Some re-
chargeable appliances may damage
the Power Inverter or the appliance.
When rst using a rechargeable
device, check its temperature for the
rst 10 minutes. If it becomes abnor-
mally hot, do not use this device with
the Inverter.
This device is designed for use in12.
12 VDC, negative ground systems
only.
Allow adequate ventilation. Do not13.
cover this unit while it is plugged
in. This unit generates heat; without
proper ventilation it may overheat,
potentially causing a re hazard.
Leave this device unplugged14.
whenever the car’s engine is

not use more than 80 watts during
continuous operation, otherwise the
Inverter may overload.
Note: This unit has an automatic shut off
feature if output is over 125 watts or if
input is under 10.5VDC.
Caution: Some rechargeable appliances
may damage the Power Inverter
or the appliance. When rst using
a rechargeable device, check the
inverter’s temperature for the rst 10
minutes. If it becomes abnormally
hot, do not use this device with the
Inverter.
Caution: It is recommended that the ve-
hicle be running when you rst con-
nect the Power Inverter. Thereafter
the engine can be on or off. If you run
the Power Inverter with the engine
off it is recommended that you start
and run the engine every hour for at
least 10 minutes to recharge the bat-
tery. Doing this will help prevent any
unexpected shutdown of the equip-
ment. This will also help ensure that
there will be enough battery power
to start the vehicle. Due to the risk
of carbon monoxide inhalation, do
not run the vehicle’s engine within
an enclosed area.
You should not use your car battery
to power the Inverter for extended pe-
riods of time with appliances requir-
ing high continuous load levels. The
battery may become drained to the
point that it will not be able to start
your car.
Note: Deep cycle (marine and RV) bat-
teries can be charged more times
than a car battery, and are a better
choice for repeated use of the Power
Inverter.
Do not discharge your car battery
more than 10% of its total capacity,
and deep cycle batteries more than a
50% discharged state.
MAINTENANCE
Keep this unit clean and dry. Discon-
nect the unit before cleaning. Clean
only the outside of this unit with a
soft, dry cloth; never clean this unit
with water or harsh cleaners.
Discharge unit before continuing.1.
