Determining the maximum load of connected devices
WARNING!
DO NOT
overload your power inverter! Overloading the power inverter, even for a
short time, could result in serious damage to the power inverter and/or to the connected
device.
A few simple steps are necessary to avoid overloading the power inverter:
• Identify all devices that you would like to power.
• Add up the total wattage of devices that will be powered. The wattage can be found on the
individual device’s rating plate, as well as in the instruction manual.
IMPORTANT!
In some cases, the wattage might not be listed on the devices you want to connect to the
power inverter. In that case, calculate the wattage using the following equation:
VOLTS x AMPERE = WATTS
Formula: 120 Volts x
X
Amperes =
XXXX
Watts
Example: 120 Volts x
2
Amperes =
240
Watts
CAUTION!
Understand the difference between rated (running) wattage and surge
(starting)
wattage.
The
RATED (RUNNING) WATTAGE
is the average amount of power that a device consumes
continuously.
The
SURGE (STARTING) WATTAGE
is the amount of power that a device consumes at start-
up for a limited period of time (2–3 seconds). Some devices (e.g. induction motors of drills
and fans) may have a start-up surge of 3 to 7 times the rated wattage.
IMPORTANT!
The power inverter can supply momentary surge power that is higher (600 W) than
its maximum power rating (300 W). Some products with a rated wattage lower than the
maximum power rating for your power inverter may still exceed the power inverter's
surge capability and trigger an overload shutdown.
Products rated with the following power and surge ratings or less can be connected to the
power inverter.

IMPORTANT!
The wattages given on next page are estimates. The actual wattage required for your devices may
differ from those listed. Be sure to check the specific wattage requirements on the rating
label and in the operating instructions of devices to be used.
