Thank you for purchasing the NPower 200W Power Inverter, a high
performance solution to use household power while on the road. Connected to
the 12V volt output in your vehicle, the inverter efficiently and reliably supplies
115V/60Hz AC power for a wide variety of loads, such as all kinds of jacklights,
TV sets, audio/video systems and electromotion tools with power consumption
under 200 watts. It has been tested and found to be in line with the requirement
of ETL certification. With proper care and appropriate usage, it will give you
years of dependable service in your car, truck, RV and boat.
The inverter has the safety features such as over input voltage shut off, low
input voltage shut off, low input voltage alarm, low voltage turn-off resume, over
heating self-lock, overload self-lock, short circuit protection, built-in internal
backup DC fuse. The LED indicator will directly display input power and errors.
The unit is not designed to be waterproof. It applies to the ambient temperature
for 32°F~104°F(0°C~40°C) .
1. INTRODUCTION
2. IMPORTANT SAFETY INFORMATION
For safe and optimum performance, the inverter must be installed and used
properly. Carefully read and follow the guidelines in this guide and give special
attention to the CAUTION and WARNING statements.
CAUTION
Instructions provide information that could damage your inverter or equipment
connected to it!
WARNING
Instructions provide information on conditions that could result in personal
injury or loss of life!
Shock hazard! Keep away from children!
3.
The inverter produces the same potentially lethal AC power as normal
household outlets. It is suggested that you treat it as normal AC outlet.
The case to the unit may become very warm under high power
operation reaching 140
℉
(60
℃
). Be sure that there is at least 2 in (5cm)
of unobstructed air space around the entire surface of the inverter at all
times. During use, do not place materials that could be damaged by
heat near the unit.
Do not operate the unit near flammable fumes or gases such as the
cabin of a gasoline power boat, or near propane tanks.
Do not operate the unit in an enclosed area that contains automotive
type lead-acid batteries. This type of battery emits explosive hydrogen
gas which can be ignited by sparks.
Always make all AC connections before making DC connections or the
components built into the inverter can become energized producing an
electrical shock hazard. Never work on the AC wiring without first
physically disconnecting the DC connections.
Caution
Do not connect the unit to live AC power circuits or there would be damage
to the inverter. Do not connect any AC device which has its neutral conductor
Some chargers for small nickel-cadmium batteries can be
damaged if connected to the unit. Do not use the unit on the
following items:
Small battery-operated appliances such as flashlights,
razors and nightlights those can be plugged directly into an AC
outlet to recharge.
Certain battery chargers for battery packs used in hand
power tools. These chargers will have a warning label indicating
that dangerous voltages are present at the battery terminals.
Connect the unit to batteries with a normal output of 12V DC
only. As 6V batteries voltage is too low, and a 24V battery

Failure to follow these safety guidelines will result in personal injury and/or
the damage to the unit. It may also be void of the warranty.

voltage is too high which will damage the unit.
Additional Safety Guidelines！
Do not insert any foreign objects into the unit outlets, vents or fan openings.
Do not expose the unit to rain, water or any other liquid.
Do not connect the unit to any utility power distribution systems or branch
circuits.
Do not use the inverter in temperatures over 104 (40 ) or under 32 (0 ).
Failure to follow these safety guidelines will result in personal injury and/or the
damage to the unit. It may also be void of the warranty.

Your 200W Power Inverter supplies 200 watts of continuous power with 400
watts of surge power. When you turn on an appliance or a tool that operates
using a motor or tubes, it requires an initial surge of power to start up. This
surge of power is referred to as the “starting load” or “peak load”. Once
started, the tool or appliance requires less power to continue to operate. This
is referred to as the “continuous load” in terms of power requirements. You
will need to determine how much power your tool or appliance requires to
start up and its continued running power requirements.
The inverter should be connected to your vehicle’s 12 Volt Cigarette or power
outlet socket with the two modes of DC cables. We recommend that the
equipment or appliance switch be in the “OFF” position prior to plugging into
the AC receptacle of the inverter. The green LED light will confirm that AC
power is present.
Using the DC cable with cigarette lighter plug
1) Attach the ring type connector marked with red to the positive (+) DC
terminal on the power inverter, and attach the ring connector marked with
black to the negative (-) DC terminal.
Caution!
Reverse the polarity will arouse blown fuse or damage to the inverter,
which may also be void of the warranty.
2) Tighten the nut on each DC terminal by hand until it is snug. Do not
over-tighten.
3) Insert the plug of this cable into the 12V outlet .
4) Turn on the inverter.
5) Plug the AC product(s) you wish to operate into the AC outlet(s) and switch
them on, one at a time.
6) If the Wattage draw of your devices exceeds the inverter’s capacity, the unit
will shut down and the indicator light will flash.
8.
7) When the power inverter is not in use, disconnect the 12V cigarette lighter
from 12V socket to prevent unintended battery discharge.
Using the DC cable clips
1) Follow steps 1) and 2) above to attach the ring type connectors.
2) Attach the negative (black) clip to the negative (-) battery terminal.
3) Attach the positive (red) clip to the positive (+) battery terminal. Make sure
both clips are securely connected to the battery terminals, as a loose
connection will cause the voltage to drop and may cause the cables to
overheat, resulting in equipment damage or fire.
4) Turn on the inverter.
5) When the power inverter is not in use, disconnect the DC cable clips from the
battery to prevent slight discharge of battery.
5. Operating the inverter
1) When properly connected to a 12V outlet or battery, turning on the inverter,
will illuminate the green LED light, and deliver AC power to the outlet(s).
2) Plug the AC product(s) you wish to operate into the AC outlet(s) and switch
them on, one at a time.
Caution!
If there are one more AC products connecting to the inverter, turn on the larger
power product first.
Through its AC outlet, the inverter is capable of powering most 110-volt
products that use 200 watts or less.
The unit will operate from input voltages ranging from 11.0V to 15.0V DC.
As the battery is used, its voltage begins to fall. When the inverter senses that
the voltage at its DC input has dropped to the range of 10.7~11.3V DC, an
audible alarm sounds. This allows time for computers or other sensitive devices
to be shut down. If the audible alarm is ignored, the inverter will automatically
9.
shut down when the voltage dropped to the range of 10.2~10.8V DC. The red
LED indicator illuminates, indicating a fault. This protects the battery from
being over-discharged. Turn off any devices that the inverter is powering.
When input voltage rose to 11.7V~12.3V DC, inverter restores normal.
Caution!
Most vehicle batteries are designed to provide short period of very high
current for starting the engine. They are not designed for a constant “deep
discharge”. Constantly operating the unit from a vehicle battery until the low
voltage shut off will affect the life of the battery. If you are operating electrical
products for extended periods of time, you should consider connecting the
unit to a separate deep discharge battery.
Should a defective battery charging system cause the battery voltage to rise
to the range of 15.0V~16.0VDC, the inverter automatically shuts down; and
the red LED lights.
Caution！
Although the inverter incorporates protection against over-voltage, it
may still be damaged if the input voltage exceeds 16 volts.
If an AC product rated higher than 200W (or which draws excessive surge
power) is connected, the inverter will shut down. The red LED light will light.
The unit will shut down automatically if the inverter exceeds a safe operating
temperature due to insufficient ventilation or a high-temperature environment;
and the red LED indicator lights.
The cooling fan is designed to operate only when output power is greater
than approximately 75W.
Battery Operating Time
Operating time will vary depending on the charge level of the battery, its
capacity and the power level drawn by the particular AC load. With a typical
