• 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.

PORTABLE COMPRESSOR
The built-in 12 volt DC compressor is the ultimate compressor for all vehicle tires,
trailer tires and recreational inflatables. Three different sized nozzle adapters are
supplied. Each nozzle adaptor will screw onto the end of the SureFit® nozzle
connector at the free end of the compressor hose. The compressor hose with
tire fitting is stored in the compressor hose storage compartment. Refer to the
"Features" illustration for locations of compressor hose. The compressor power
button and compressor pressure control buttons are located on the control panel on
the front of the unit.
Before proceeding, check the unit's battery status on the LCD screen. Four solid bars
in the battery icon indicates a full battery. When the battery level is nearly empty
with only one solid bar, the unit MUST be recharged before use.
The compressor may be used by removing the air hose from the storage hatch and
if required, fitting an appropriate nozzle adapter to the air hose. 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.
