BEFORE USING YOUR INVERTOR
1
RECHARGEABLE APPLIANCES
Certain rechargers for small
nickel cadmium batteries
can be damaged if connected
to the unit. Two types of
equipment are particularly
prone to this problem:
1. Small battery operated
appliances that can be
plugged directly into
an AC receptacle for
recharging, including
flashlights, razors, and
night lights.
2. Certain battery chargers
for battery packs used
in hand power tools,
specifically those that
have a WARNING label
stating that dangerous
voltages are present at
the battery terminals.
Problems do not occur with
the vast majority of battery
operated tools, most of which
use a separate charger or
transformer that plugs into
an AC receptacle and produces
a low voltage output. If the
label on your tool’s AC adapter
or charger states that it
produces a low voltage AC or
DC output (less than 30 volts)
you can safely power the
charger.
In order to check the
performance of your
unit before using it, please
have the following
on hand:
1. A 12 volt DC power source
(such as a vehicle battery).
2. A test load such as a lamp
or other small appliance
that can be plugged into
the AC receptacle on the
inverter.
Power Source
You will need an 10.4 to
11.4 volt DC power source
capable of supplying enough
current to run the test load.
As a rough guide, divide the
wattage of the test load by 10
to get the current (in amperes)
that the power source must
supply. A fully charged
standard automotive battery
will work fine.
Connecting to the
Power Source
Your unit comes with
a 24 inch cable and cigarette
lighter plug.
Do not connect to the power
source if flammable fumes
are present. Explosion or
fire may result.

BEFORE USING YOUR INVERTOR

The location where you should
use your unit must be:
• dry–Do not use the unit
where water can drip or
splash on it.
• cool–Ambient air
temperature should be
between 30˚ and 105˚ F
(0˚ and 40˚ C). The cooler
the better.
• ventilated–Allow at least
1 inch (3 cm) of clearance
around the unit for proper
air flow. Make sure that
ventilation openings on the
ends of the unit are not
obstructed.
To prevent fire, do
not cover or obstruct
ventilation openings.
The inverter must only
be connected to batteries
with a nominal output
voltage of 12 volts.
It will not work with
a 6 volt battery, and
will be damaged if it is
connected to a 16 volt
or greater battery.

Before Using Your Invertor
(continued)
To connect your inverter
to the power source:
1. If the power source is a DC
power supply, switch it off.
2. Insert the cigarette lighter
plug into your vehicle’s
cigarette lighter.
3. Press and release
power button.
4. Connect load to AC outlet
or USB port.

Power Output
AC Output:
Your unit will deliver
200 watts continuously.
(NOTE: the wattage rating
applies to resistive loads.)
USB Outputs:
5V/2.1A continuous output.
Input Voltage
Your unit will operate from
input voltage ranging from
10.4 to 14.4 volts. Optimum
performance occurs when the
voltage is between 12 and
14 volts.
The inverter will automatically
shut down if the input voltage
drops below 10.0 ± 0.3 volts.
This protects the battery
from being over-discharged.
The inverter will restart when
the input voltage exceeds
12.0 ± 0.3 volts.
The inverter will also shut
down if the input voltage
increases to 15.5 ± 0.5 volts.
This helps protect the unit
from damage due to excessive
input voltage. Although the
inverter is protected in this
way, it may still be damaged
should the input voltage
exceed 16 volts.
Automatic Shutdown
The unit will automatically
go into thermal shutdown if
it becomes overheated due to
excessive input voltage, poor
circulation or high ambient
temperature.

To apply power to the unit,
simply plug in to 12 Volt DC

Power/Fault Indicator
The “fault” indicator of your
unit will light whenever the
unit detects excessively high
or low input voltage,
or unit begins to overheat.
CAUTION NOTE: Make sure
you unplug inverter from
power source before you
leave your vehicle.

Maintaining Your Inverter
Your unit requires very little maintenance to keep
it operating properly. The exterior of the unit should
be cleaned periodically with
a damp cloth to prevent accumulation of dust and dirt. Keep
vents and fans free from dust or debris.

For each piece of equipment
you will be powering
with your unit, you must
determine the battery’s
capacity (how long the
battery can deliver a
specific amount of current).
For example, automotive
batteries usually provide
25 amperes of current.
A battery with a reserve
capacity of 180 minutes
can deliver 25 amperes for
180 minutes before it is
completely discharged.
Calculate the total watthours of energy consumption
(power X operating time),
then divide the watt-hours
by 10 to determine how may
12 volt ampere hours will be
consumed.

How Your Cobra® Power
Inverter Works
The Cobra® Power Inverter takes
low voltage DC (direct current)
power from your automobile or
other low voltage power supply
and converts it to standard
110 volt AC (alternating
current) power like the
electrical current you have
in your home. Simply by
plugging your unit into your
vehicle’s cigarette lighter
socket, you can use many of
your household appliances
and electronic products in
automobiles, RVs, boats,
tractors, trucks, and virtually
anywhere else.

Output Waveform
This unit’s output waveform is
referred to as ”square wave“
or ”modified sine wave.“ It is
a stepped waveform designed
to have characteristics similar
to the sine wave shape of
utility power. A waveform
of this nature is suitable for
most
AC loads (including linear
and switching power supplies
used in electronic equipment,
transformers and motors).
