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.

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.
