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 is 
produces a low voltage AC or 
DC output (less than 30 volts) 
you can safely power the 
charger.

BEFORE USING YOUR INVERTOR

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  
14.4 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 connects  
directly into the cigarette 
lighter socket of your car.

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.

2.

 Insert the cigarette lighter  

  plug into your vehicle’s  
  cigarette lighter.

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.

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.

CONTROLS & INDICATORS

Powering Up

To apply power to the CPI190, 
simply plug in to 12 Volt DC 
source (cigarette lighter).

Power/Fault Indicator

The “fault” indicator of your 
CPI190 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.

OPERATING LIMITS 

INPUT VOLTAGE/AUTO SHUTDOWN

Power Output

AC Output:

 

Your CPI190 will deliver  
130 watts continuously.  
(

NOTE:

 the wattage rating 

applies to resistive loads.)

USB Output:

 

5 Volt continuous output.

Input Voltage

Your CPI190 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.

POWER CONSUMPTION

For each piece of equipment 
you will be powering with 
your CPI190, 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 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.
