may lead to serious injury or death.
1.15 Do not place the converter in direct sunlight. The ideal air temperature for
operation is between 50° and 80°F.
1.16 Only connect the power converter to a 12V accessory outlet or 12V battery.
• 5 •
1.17 Do not attempt to connect the converter to any other power source, including
an AC power source. Connecting to a 6V or 16V battery will cause damage
to the converter.
1.18 Do not modify the AC or USB receptacle in any way.
1.19 Do not try extending or otherwise changing the 12V power cord attached to
your converter.
1.20 Incorrect operation of your converter may result in damage and personal injury.
1.21 This device does not include an internal Ground Fault Circuit Interrupter
(GFCI).
1.22 Use only 15A fuses.
1.23 Restrictions on Use: This converter may not be used with life support
devices or systems. Failure of this converter can reasonably be expected to
cause failure of that life support device or system, or to affect the safety or
effectiveness of that device or system.
2. CONVERTER FEATURES
1. LED indicator light (Green = Power ON, Red = Overload, Alarm)
2. Standard electrical 120V AC outlet
3. 12-Volt power plug
4. USB port
5. Low-battery protection
3. BEFORE USING YOUR POWER CONVERTER
When you turn on a device or a tool that runs on a motor, the device goes
through 2 stages:
1. Start Up – Requiring an initial surge of power (commonly known as the
“starting” or “peak” load).
2. Continuous Operation – Power consumption drops (commonly known as
the “continuous load”).
The wattage (WATTS) or amperes (AMPS) can normally be found stamped
or printed on most devices and equipment, or in the user’s manual.
Otherwise, contact the manufacturer to nd out whether the device you want
to use is compatible with a modied sine wave.
• 6 •
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x wattage.
In general, the startup load of the device or power tool determines whether
your converter has the capability to power it.
Always run a test to establish whether the converter will operate a particular
piece of equipment or device. In the event of a power overload, the converter
is designed to automatically shut down.
This safety feature prevents damaging the converter while testing devices and
equipment within the wattage range of the converter.
IMPORTANT: This converter is designed to power 100 watt devices or less
when used with the vehicle’s 12 volt accessory port.
NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles.
Some vehicles may allow the full output. To use the full output, you must
purchase a 12 volt accessory outlet-to-battery battery clips adapter and
connect the inverter directly to the battery. If the fuse blows when you switch
on the device you are trying to use, you must either use a smaller device or
the battery clips adapter.
IMPORTANT: This converter uses a modied sine waveform (diagram A)
which is not quite the same as power company electricity (diagram B). For the
following devices, we strongly recommend that you use caution and check the
device’s manual to make sure it is compatible with modied sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line lter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers
Using the converter with any of these devices may cause the device to run
warmer or overheat.

4. OPERATING INSTRUCTIONS
1. If connecting in a vehicle, remove the cigarette lighter from its outlet.
2. Make sure the device to be operated is turned OFF.
3. Push the 12V power plug rmly into the outlet.
4. The LED indicator light should glow GREEN, verifying the converter is receiving
power.
5. Plug the device into the converter’s AC outlet or USB port.
6. Turn the device on.
7. To disconnect, reverse the above procedure.
NOTE: This converter has a cooling fan that runs continuously. Do NOT
leave it plugged into the vehicle when the engine is not running, or it will
drain the battery.
NOTE: You may hear a “buzzing” sound being emitted from inexpensive
sound systems when operated with the converter. This is due to ineffective
lters in the sound system’s power supply. Unfortunately, this problem can
only be resolved by purchasing a sound system with a higher quality power
supply or higher quality lter.
5. POWER SOURCE
To get the best performance out of your converter, we recommend that you
use it with the vehicle’s engine running.
Your average automobile or marine battery at full charge will provide an ample
power supply to the converter for approximately 3 hours when the engine is off.
The actual length of time the converter will function depends on the age and
condition of the battery and the power demand being placed by the device being
operated with the converter.
• 8 •
If you decide to use the converter while the engine is off, we recommend
you turn OFF the device plugged into the converter and disconnect the
converter’s plug from the 12V accessory outlet before starting the engine. To
maintain battery power, start the engine every 2 to 3 hours and let it run for
approximately 30 minutes to recharge the battery.
Although it is not necessary to disconnect the converter when turning over the
engine, it may briey cease to operate as the battery voltage decreases. While the
converter draws very low amperage when not in use, it should be unplugged to
avoid battery drain.
6. LED INDICATOR AND SHUTDOWN PROTECTION
The GREEN LED automatically lights when plugged into a 12V DC source
and the RED LED will light under the following conditions:
1. When the power input from the vehicle’s battery drops to approximately
10 volts, low battery shutdown occurs and converter shuts off. Solution:
recharge or replace the battery.
2. When the power input from the vehicle’s battery exceeds 15 volts, high
voltage protection occurs. Solution: reduce the voltage range to between 12
and 14 volts.
3. The continuous load demand from the equipment or device being
operated exceeds the continuous load rating of the converter being used.
Solution: use a higher capacity converter or lower rated device.
4. The case temperature becomes hot (exceeds 145°F). Solution: allow
the converter to cool. Do not block the cooling slots or air ow over and
through the converter. Reduce the load on the converter to the continuous
rated output.
RESET: To reset after shutdown occurs, remove the 12V plug from the
accessory outlet. Check the source of the problem and correct. Reinsert the
12V plug into the accessory outlet.
• 9 •
7. IF THE CONVERTER’S FUSE BLOWS
Your power converter is tted with a fuse, which should not have to be
replaced under normal operating conditions. A blown fuse is usually caused
by reverse polarity or a short circuit within the device or equipment being
operated.
If the fuse does blow:
1. Disconnect the device or equipment immediately.
2. Find the source of the problem, and repair it.
3. Install a new 15A fuse. The fuse can be found on the end of the plug on
the converter.
4. Do not over-tighten the fuse cap; nger-tight is sufcient.
ATTENTION: Do not install a fuse higher than 15A, as this may damage the
converter. Make sure to correct the cause of the blown fuse before using the
converter again.
8. TROUBLESHOOTING
PROBLEM REASON SOLUTION
The RED LED is lit,
or converter does not
function.
