Keep the jump starter dry.3.
DO NOT allow the jump starter to come into contact with rain or moisture.4.
DO NOT operate the jump starter if you, the jump starter, the device being operated or 5.
any other surfaces that may come in contact with any power source are wet. Water and
many other liquids can conduct electricity, which may lead to serious injury or death.
Do not place the jump starter on or near heating vents, radiators or other sources of heat.6.
Do not place the jump starter in direct sunlight. The ideal air temperature for operation 7.
is between 50° and 80°F.
Do not use the inverter near an open engine compartment where fumes or gases 8.
may accumulate.
Do not modify the AC receptacles in any way.9.
Using the Inverter8.10
It is important to know the continuous wattage of the device you plan to use with the inverter.
The jump starter must be used with devices drawing 400 watts or less. If the wattage is not
marked on the device, use only devices that draw less than 4 Amps of AC current.
Devices like TVs, fans or electric motors require additional power to start (commonly
known as the “starting” or “peak power”). The jump starter can supply a momentary
surge in wattage; however, even devices rated less than the maximum 400 watts can
exceed the inverter’s surge capability and cause an automatic overload shutdown.
Do not use the inverter with a product that draws a higher wattage than the inverter can
provide, as this may cause damage to the inverter and the product.
Make sure the device you are using is compatible with a modied sine wave inverter.
Always run a test to establish whether the inverter will operate a
particular piece of equipment or device.
In the event of a power overload, the inverter is designed to automatically shut down.
This safety feature prevents damaging the inverter while testing devices and equipment
within the 400-watt range.
If powering more than one device, start one device at a time to avoid a power surge
and/or inverter overload. The surge load of each device should not exceed the inverter’s
Continuous Operation wattage rate.
If you are using the power inverter to operate a battery charger, monitor the temperature
of the battery charger for about 10 minutes. If the battery charger becomes abnormally
warm, disconnect it from the inverter immediately.
You can use an extension cord from the inverter to the device without signicantly
decreasing the power being generated by the inverter. For best operating results, the
extension cord should be no longer than 50 feet.
This inverter uses a nonsinusoidal waveform. Therefore, we do not
recommend you use it to power the following devices:
Switch Mode Power Supplies1.
Linear Power Supplies2.
Class 2 Transformers3.
Line Filter Capacitors4.
Shaded Pole Motors5.
Fan Motors6.
Microwave Ovens7.
Fluorescent and High Intensity Lamps (with a Ballast)8.
Transformerless Battery Chargers9.
Doing so may cause the device to run warmer or overheat.
