RECHARGEABLE APPLIANCES
1
CAUTION
Certain rechargers for small
nickel cadmium batteries can
be damaged if connected to
the CPI 150 BK/WH. 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.
1
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 is produces a low
voltage AC or DC output
(less than 30 volts) you
can safely power the charger
with your CPI 150.
In order to check the
performance of your
CPI 150 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 11 to
15 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.
QUICK CHECKOUT
2
Connecting to the
Power Source
Your CPI 150 BK/WH comes
with a 24 inch cable and
detachable cigarette lighter
plug that converts to an
airplane 12 volt female
connector.
WARNING
Do not connect to the power
source if flammable fumes
are present. Explosion or
fire may result.

QUICK CHECKOUT

Quick Checkout (continued)
To connect your inverter
to the power source:
1. If the power source is a DC
power supply, switch it off.
Power Cord
2. Connect power cord to
the inverter.
3. Insert the cigarette lighter
plug into your vehicle’s
cigarette lighter.
4. For airline application, remove
lighter plug from cable.
3
Airplane Plug
Note: Some airplanes are
equipped with cigarette
lighter type socket.
5. Status LED on top of unit
will illuminate indicating
“on” status.
6. Plug the power cord from
the test load into the
inverter’s AC receptacle.
Testing
The inverter will come on
automatically. It should supply
power to the load. If the
inverter does not appear to
work properly, refer to the
Troubleshooting Guide on
page 7.
5V USB Outlet
The location where you should
use your CPI 150 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.
CAUTION
To prevent fire, do not cover
or obstruct ventilation
openings.
OPERATION
3
CAUTION
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 battery.

Power/Fault Indicator
The "fault" indicator of your
CPI 150 will light whenever
the unit detects excessively
high or low input voltage, or
begins to overheat.

CAUTION NOTE: Make sure
you unplug inverter from
power source before you
leave your vehicle.
INPUT VOLTAGE/AUTO SHUTDOWN
Power Output
AC Output:
Your CPI 150 will deliver
150 watts continuously. It
can deliver 180 watts for
about 30 minutes, after
which it must cool for
about 15 minutes before
it can resume operation at
150 watts. (
wattage rating applies to
resistive loads.)
USB Output:
5 Volt continuous output.
NOTE: the
Input Voltage
Your CPI 150 will operate
from input voltage ranging
from 10 to 15 volts.
Optimum performance occurs
when the voltage is between
12 and 14 volts.
OPERATING LIMITS
5
The inverter will automatically
shut down if the input
voltage drops below 10.0 ±
0.3 volts. This protects the
battery from being overdischarged. 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.

MAINTENANCE & SERVICE
Maintaining Your
Inverter
Your CPI 150 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.

If your unity is under
warranty, it will either be
repaired or replaced upon
receipt, depending on the
model. If your unit is out of
warranty, you will receive a
letter informing you of the
repair or replacement charge.
For each piece of equipment
you will be powering with
your CPI 150, 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.
POWER CONSUMPTION
Calculate the total watt-hours
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 CPI 150 into
your vehicle’s cigarette lighter
socket, you can use many of
your household appliances and
electronic products in
automobiles, airplanes, 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).
