1. Introduction
Thank you for purchasing this VOLTEC power inverter, a high
performance solution to using household power while on the road. Connected
to a 12V volt outlet, the inverter efficiently and reliably supplies 115V/60Hz
AC power for a wide variety of loads, such as TV sets, gaming systems, cell
phones and portable entertainment devices. Our line of power inverters are
designed to meet and exceed your quality expectations with ETL certification.
With proper care and appropriate usage, this inverter will give you years of
dependable service in your car, truck, RV and boat.
2. Important Safety Information
For safe and optimum performance, the inverter must be installed and
used properly. Carefully read and follow the guidelines below:
Warning
The inverter produces the same AC power as normal household outlets and
thus has a shock hazard. Please do not allow children to use the inverters
unattended
•Be sure that there is at least 2 in (5cm) of unobstructed air space
around the entire surface (top and sides) of the inverter at all times.
During use, do not place materials that could be damaged by heat
near the unit.
•Do not operate the unit near flammable fumes or gases, such as near
propane tanks
•Do not operate the unit in an enclosed area that contains lead-acid
batteries. This type of battery emits explosive hydrogen gas which
can be ignited by spark.
•Connect AC devices before DC ones or the components built into
the inverter can become energized producing an electrical shock
hazard.
•Do not connect the unit to live AC power circuits or there would be
damage to the inverter.

- 4 -
•Connect the unit to only to 12V DC power supplies (6V is too low,
and 24V will damage the unit).
•Do not insert any foreign objects into the unit outlets, vents or fan
openings.
•Do not expose the unit to rain, water or any other liquid.
•Do not connect the unit to any utility power distribution systems or
branch circuits.
•Do not use the inverter in temperatures over 104(40) or under
32(0).
Caution
Do not use the unit on the following items:
ySmall nickel-cadmium battery-operated appliances such as flashlights,
razors and nightlights
yBattery chargers for battery packs used in hand power tool that have a
warning label indicating dangerous voltages are present at the battery
terminals.
Failure to follow these safety guidelines may result in personal injury
and/or the damage to the unit. It may also void the warranty.

3. Features
Figure 1
1. Cooling Fan and Ventilation Openings— The high speed cooling fan
protects the inverter from over-heating. And the ventilation openings
should be kept clear!
2. LED Indicator—When there is DC power input, the green LED Indicator
is on; a Red light indicates that the inverter has shut down because of low
or high input voltage.
3. USB Port— Offer 5V power to USB equipment.
4. AC Outlets— receptacles for 120V AC products with a total continuous
power equal to the wattage (W) of your inverter.
5. Lighter Plug—Insert this end into a 12V DC receptacle
6. Replaceable Fuse—10A Mini Slip Fuse.
7. Cooling Fan and Ventilation Openings— The high speed cooling fan
protects the inverter from over-heating. And the ventilation openings
should be kept clear!
8. Replacing the fuse - Remove the blown fuse from the plug by gently
unscrewing the tip of the lighter plug, and replace the fuse with a 10A
Mini Slip Fuse.

4. Connecting and operating the inverter
When connecting the unit, please be sure to follow the guideline,
cautions and warnings mentioned in this manual. The inverter should be
connected to your vehicle’s 12 V battery or power outlet socket. No devices
should be plugged into the inverter until the inverter is properly connected and
the inverter’s power indicator is active.
Please follow the following to connect your inverter:
1) Plug the inverter directly into a 12 Volt Cigarette or Power Outlet
Socket.
2) Plug the AC product(s) you wish to operate into the AC outlet(s) and
switch them on, one at a time.
3) If the Wattage draw of your devices exceeds the inverter’s capacity,
the unit will shut down and the indicator light will flash.
4) When the power inverter is not in use, disconnect the DC cable clips
from the battery to prevent unintended battery discharge.
Caution
As the battery is being used, its voltage begins to fall. When the inverter
senses that the voltage at its DC input has dropped to the range of
9.7V~10.3VDC, the unit will automatically shut down and the red LED
indicator will light, indicating a fault. This protects the battery from being
over-discharged. Turn off any devices that the inverter powers. When input
voltage rose to 11.7V~12.3V, the inverter restores normal.
Caution!
Most vehicle batteries are designed to provide short period of very high
current for starting the engine. They are not designed for a constant “deep

- 7 -
discharge”. Constantly operating the unit from a vehicle battery until the low
voltage shut off will affect the life of the battery. If you are operating electrical
products for extended periods of time, you should consider connecting the unit
to a separate deep discharge battery.
5. Troubleshooting
a) Battery Operating Time
Operating time will vary depending on the charge level of the battery, its
capacity and the power level drawn by the particular AC load. Below is a list
of common appliances and their estimated consumption:

When using a vehicle battery as a power source, it is strongly
recommended to start the vehicle every hour or two to recharge the battery
before its capacity drops too low. The inverter can operate while the engine is
running, but the normal voltage drop that occurs during starting of the engine
may trigger the inverter’s low voltage shutdown feature.
b) Interference with Electronic Equipment
Generally, most AC products operate with the inverter just as they would
with household AC power. Below is information concerning two possible
exceptions:
1) Buzzing and in audio systems and radios
Some stereo systems and AM-FM radios have inadequate internal power
supply filtering and “buzz” slightly when powered by the inverter. Generally,
the only solution is an audio product with a higher quality filter.
2) Television interference
The inverter is shielded to minimize its interference with TV signals.
However, with weak TV signals interference may be visible in the form of
lines scrolling across the screen. The following should minimize or eliminate
the problem:
zIncrease the distance between the inverter and the TV, antenna and

- 9 -
cables.
zAdjust the orientation of the inverter television, antenna and cables.
zMaximize TV signal strength by using a better antenna and use
shielded antenna cable where possible.

PROBLEM CAUSE SOLUTION
Battery is defective Replace battery
Blown fuse Check and replace fuse
No power, no
indicator. Lose cable connections Check the connection to the
battery. Tighten as required.
AC products connected are
rated at more than the
Wattage load of the
inverter; overload
shutdown has occurred.
Reduce load.
AC products at less than
the Wattage load of the
inverter, but high starting

Standard
“average-reading” AC
voltmeter used to measure
output voltage, resulting in

rated.
Use a larger battery to make
up for increased power
