cigarette lighter type plug connection or airplane adapter.
-Do
not operate the inverter near flammable materials,
fumes
or gases.
-Provide adequate ventilation and refrain
from placing
items on
or around the inverter during operation.
-Proper cooling

use when wet.
-DO NOT insert foreign objects into the AC outlet or the
USB outlet.
-DO
NOT attempt to connect or set up the unit or its
components
while operating your vehicle. Inattention to
the road may result in aserious accident.

This inverter is an electronic device that converts low
voltage DC (direct current) electricity from abattery to
110/120 Volt AC (alternating current) household power. In
designing this inverter, we have incorporated design
techniques previously employed in
computer power
supplies. This result of these design innovations is asmaller,
lighter and easier-to-use power inverter. The AII-in-one
mobile power inverter converts power in two stages. The
first stage
is aDC-to-DC conversion process that raises the
low voltage DC at the inverter input to 145 volts DC. The
second
is a MOFSFET bridge stage that converts the high
voltage
DC into 110/120 volts, 60 Hz AC.
AII-in-one mobile power inverter Output Waveform
This AC output waveform of this inverter is known as a
modified sine wave.
It is astepped waveform that has
characteristics similar
to the sine wave shape of utility
power. This type of waveform is suitable for most AC loads,
including linear and switching power supplies used in
electronic equipment, transformers, and small motors.

The lIIodlfled sine wave produced

The modified sine wave produced by this inverter has an
RMS (root mean square) voltage of 110/120 volts. Most
AC voltmeters (both digital and analog) are sensitive to
the average value of the waveform rather than the RMS
value. They are calibrated for RMS voltage under the
assumption
that the waveform measured will be apure
sine wave.
Non-TRUE RMS meters will read about 20 to
30 volts low when measuring the output of this inverter.
For accurate measurement of the output voltage of this
unit,
use a TRUE RMS reading voltmeter such as aFluke
87, Fluke 8080A, Beckman 4410 or Triplett 4200.
ACAUTIONS
Rechargeable Devices
• Certain rechargeable devices are designed to be
charged by plugging them directly into an AC
receptacle. These devices may damage the inverter
or the charging circuit.
• When using a rechargeable device, monitor its
temperature for the initial ten minutes of use to
determine if it produces excessive heat.
• If excessive heat is produced, this indicates the device
should not be used with this inverter.
•This problem does not occur with most of the battery-
operated equipment. Most of these devices use a
separate charger or transformer that is plugged into
an AC receptacle.
•The
inverter is capable off running most chargers and
transformers.

Once the vehicle accessory adapter is properly connected to a 12-Volt DC power
source, the bi-color LED indicator lights GREEN when the inverter is connected to
DC power and the unit power is ON. (If the bi-color LED indicator lights RED, refer
to the "Troubleshooting" section on page 12 of this manual.)
ALWAYS TURN THE INVERTER ON BEFORE APPLYING
POWER TO THE DEVICE.
The standard North American 110/120 volt AC and USB
outlets allow the user to operate multiple devices
simultaneously. Simply plug the equipment
into the unit.
~ Note: Ensure wattage of all equipment simultaneously
plugged
into the power inverter does not exceed 120-
watts continuous.
Rated Versus Actual Current Draw of Equipment
Most electrical tools, appliances, electronic devices and
audio/visual
equipment have labels that indicate the power
consumption in amps or watts. Be sure the power
consumption of the item to be operated is below 120-
watts.
If the power consumption is rated in amps AC, simply
multiply by the AC volts (110/120) to determine the power.
Resistive loads are the easiest
for the inverter to run;
however,
it will not operate larger resistive loads (such as
electric stoves and heaters), which require far more wattage
than the inverter can deliver. Inductive loads (such as TVs
and stereos) require more current to operate than do
resistive loads
of the same wattage rating.
Once the vehicle accessory adapter is properly connected to a 12-Volt DC power
source, the bi-color LED indicator lights GREEN when the inverter is connected to
DC power and the unit power is ON. (If the bi-color LED indicator lights RED, refer

Operating Tips
The AII-in-one mobile power inverter should only be
operated in locations
that are:
•
DRY-Do not allow water or other liquids to come into
contact with the inverter.
•COOL-Surrounding air temperature should ideally be
0-40°C (32-1 04°F).
Keep the inverter away from direct
sunlight, when possible.
•
WELL-VENTILATED-Keep the area surrounding the inverter
clear
to ensure free air circulation around the unit. Do not
place items on or over the inverter during operation. The
unit will shut down if the internal temperature gets too

Common AudioNisual Problems
Problem: Buzzing Sound In Audio Systems
Some inexpensive stereo systems and boom boxes make a
buzzing sound when operated
from the inverter, because
the power supply in the electronic device does not properly
filter
the modified sine wave produced by the inverter. The
only solution to this problem is to use asound system that
has ahigher quality power supply.
The AII-in-one mobile power inverter is shielded to
minimize interference with TV signals. However, in some
instances, some interference may still be visible, especially
when the
TV signal is weak. Try the following to improve
the picture:
1.Move the 120
Watt Inverter as far away as possible from
the TV set, the antenna, and the antenna cables. Use a
short AC extension cord, if necessary.
2.Adjust the orientation
of the antenna cables, and the TV
power cord to minimize interference.
3.Make sure
that the antenna feeding the TV provides an
adequate (snow-free) signal and
that high quality,
shielded antenna cable
is used.
Fault
LED Lights/Alert Buzzer Sounds
When the Power/Fault LED turns from GREEN (indicating the
unit is powered) to RED, a fault condition is present and the
unit will automatically shut down shortly. See "Protective
Features" on page 9and "Common Power Output Problems"
below.
