Before Using
When you turn on an appliance or a tool that runs on a motor, the appliance basically goes through two stages:
1. Start up - requiring an initial surge of power (commonly known as the "starting load" or "peak load".
2. Continuous operation - power consumption drops (commonly known as the "continuous load".)
Before using your power inverter, you need to calculate these loads, i.e.:
1. Starting load (at start up)
2. Continuous load (on continuous operation)
The formula for power consumption (measured in either WATTS (wattage) or AMPS (amperes) is:
AMPS x 110 (AC voltage)=WATTS
The wattage (WATTS) or amperes (AMPS) can normally be found stamped or printed on most appliances and
equipment, or in the user's manual. Otherwise, contact the manufacturer to find out whether the device you are using
is compatible with a modified sine wave inverter.
To calculate the starting load: Starting Load = 2 x WATTS
In general, the start up load of the appliance or power tool determines whether your inverter has the capability to
power it.
To calculate the continuous load (same as wattage in the above formula):
Continuous load = AMPS x 110 (AC voltage)
Attention:
Always run a test to establish whether the inverter will operate a particular piece of equipment or appliance.
In the event of a power overload, the inverter is designed to automatically shut
down. This safety feature prevents damaging the unit while testing appliances and
equipment within the 300 / 500 watt range.
IMPORTANT:
* Make sure you connect your inverter to a 12 volt power supply only. Do not attempt to connect the inverter to any
other power source, including any AC power source.
* Do not try extending or otherwise changing the 12 volt power cord attached to your inverter.
* 120 volts of current can be very dangerous. Incorrect operation of your inverter may result in damage to belongings,
personal injury or loss of life.
A. ON/OFF Rocker Switch

C. 2 X 110V AC Outlets
D. High-speed Cooling Fan
E. Fuse
F. 12V DC Plug (300W)
G. Power Input Terminal (Black = Neg, Red = Pos)

How To Connect Inverter
1. Make sure the ON/OFF rocker switch (see diagram, part A) is in the OFF (0) position.
2. Remove the 12V DC plug from its outlet in your vehicle.
3. Push the 12 volt power plug firmly into the outlet
Warning: When using the inverter’s 12V DC plug in a vehicle, car fuses limit the input rating to 150Watts. If the 12V
DC plug is used with other power supplies then it can reach max 300W ( for 10 minutes) and continuous power for
275 Watts.
For 500 Watt Modified Sine Wave Inverter only:
Connection with alligator clamps: Connect the Black cable (negative) to the Black (negative) Power input terminal and
connect the Red cable to the Red (Positive) power input terminal.
