The compressor is capable of inflating up to 120 pounds per square inch
(PSI) pressure. The compressor can operate long enough to fill up to 3
average sized tires before the battery must be recharged. Return hose to
the storage compartment after use.
IMPORTANT:
Make sure the Jump Starter Power Button has been turned
off before attempting to use the unit as a Compressor.
WARNING –
To reduce the risk of serious injury or property
damage:
Follow all safety instructions found in the “Specific Safety
Instructions for Compressors” section of this instruction manual.
CAUTION –
To reduce the risk of serious injury or property
damage:
When the compressor is operated at a low PSI, the unit may
start slowly and gradually rev up. When the compressor is operated at
higher PSIs, the unit may operate normally for several minutes, then rev
down for a few minutes before returning to normal operation. This feature
protects the unit from overheating during normal use. In any event, do not
operate compressor continuously for longer than 10 minutes, as it may
overheat. This could damage the compressor. If the compressor must
be operated for longer periods: every 10 minutes press the Compressor
Power Button to turn the compressor off, then restart after a cooling down
period of approximately 30 minutes.

120 VOLT AC PORTABLE POWER SUPPLY
Rated Versus Actual Current Draw of Equipment
Most electrical tools, appliances, electronic devices and audio/visual
equipment have labels that indicate the power consumption in amps or
watts. Be sure that the power consumption of the item to be operated is
below 500 watts. If the power consumption is rated in amps AC, simply
multiply by the AC volts (120) to determine the wattage.
Resistive loads are the easiest for this unit to run; however, it will not run
larger resistive loads (such as electric stoves and heaters), which require
far more wattage than the unit can deliver on a continuous basis. Inductive
loads (such as TVs and stereos) require more current to operate than do
resistive loads of the same wattage rating.
CAUTION:
Rechargeable devices
• Certain rechargeable devices are designed to be charged by plugging
them directly into an AC receptacle. These devices may damage the
inverter or the charging circuit.
• When using a rechargeable device, monitor its temperature for the initial
ten minutes of use to determine if it produces excessive heat.
• If excessive heat is produced, this indicates the device should not be used
with this inverter.
• This problem does not occur with most of the battery-operated
equipment. Most of these devices use a separate charger or transformer
that is plugged into an AC receptacle.
• The inverter is capable of running most chargers and transformers.
Note:
Some laptop computers may not operate with this inverter.
Power Inverter Output Waveform
The AC output waveform of this inverter is known as a modified sine wave.
It is a stepped waveform that has characteristics similar to the sine wave
shape of utility power. This type of waveform is suitable for most AC loads,
including linear and switching power supplies used in electronic equipment,
transformers, and small motors.
