Use and Care Manual
8
• 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.
Using the Dual 120 Volt AC Outlets
The two 120 volt AC outlets each are located under a protective cover on the left
hand side of the front panel (refer to the Features section to locate). The two
outlets support a combined maximum power draw of 500 watts.
1. Press the inverter power switch to turn the inverter on (I). The inverter power
indicator will light red to indicate the two 120 volt AC outlets are ready to use.
2. Lift up the cover of the 120 volt AC outlet.
3. Insert the 120 volt AC plug from the appliance into the 120 volt AC outlet.
4. Switch on the appliance and operate as usual.
Periodically check the unit’s battery status on the LCD screen by pressing the Battery
Status Button. 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
at this time.
Make sure the inverter is turned off when the unit is being recharged or stored.
Protective Features
The inverter monitors the following conditions:
Low internal battery voltage: The inverter will automatically shut down when
the battery voltage drops too low, as this can harm the battery.
High internal battery voltage: The inverter will automatically shut down when
the battery voltage is too high, as this can harm the unit.
Thermal shutdown protection: The inverter will automatically shut down when
the unit becomes overheated.
Overload/short circuit protection: The inverter will automatically shut down
when an overload or short circuit occurs.
Important Notes: The inverter power/status indicator will flash red to indicate that
one of the above fault conditions is present before automatic shutdown occurs.
Should this occur, take the following steps:
1. Disconnect all appliances from the unit.
2. Press the inverter power switch to turn the inverter off (O).
3. Allow the unit to cool down for several minutes.
4. Make sure the combined rating for all appliances plugged into the unit is 500
watts or lower and that appliance cord(s) and plug(s) are not damaged.
5. Assure there is adequate ventilation around the unit before proceeding.
12 VOLT DC PORTABLE POWER SUPPLY
The 12 volt DC power supply is located under a protective cover on the front of the
unit. Refer to the Features section to locate.
This portable power source is also for use with all 12 volt DC accessories equipped
with a male accessory outlet plug and are rated up to 5 amps.
1. Lift up the cover of the unit ‘s 12 volt DC outlet.
2. Insert the 12 volt DC plug from the appliance into the 12 volt accessory outlet
on the unit. DO NOT EXCEED A 5 AMP LOAD.
3. Switch on the appliance and operate as usual.
4. Periodically check the unit’s battery status on the LCD screen by pressing
the Battery Status Button. (Four solid bars in the battery icon indicates a full
battery. One bar indicates that the unit needs to be recharged.)
USB CHARGING PORT
The USB charging port is under the same protective cover as the 12 volt DC outlet.
Refer to the Features section to locate.
1. Press the USB power power button to turn the USB port on. A beep will sound
and the backlit LCD screen will continuously display the following:
+
Area Light
Compressor

The “5V USB” icon indicates that the USB port is ready to use.
2. Plug the USB-powered device into the USB power port and operate normally.
The USB power port remains on until the USB Power button is pressed again to turn
it off. Make sure the USB Power Button is in the off position when the unit is being
recharged or stored.
Periodically 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 at this time or the unit’s built-in
low voltage protection will activate. The unit will sound a beep 5 times, then the
USB Charging Port will automatically turn off. The unit will then display the battery
status and voltage indicator for 10 seconds before automatic shut down.
Note: This unit’s USB power port does not support data communication. It only
provides 5V DC/1000mA power to an external USB-powered device.
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.
WARNING – TO REDUCE THE RISK OF 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 PROPERTY DAMAGE:
Do not operate compressor continuously for extended periods of time
(approximately 10 minutes, depending on ambient temperatures), as it may
overheat. In such event, compressor will automatically shut down. Immediately press
the compressor power button to turn the compressor off. Restart after a cooling
down period of approximately 30 minutes.
Inflating Tires or Products With Valve Stems
1. Screw the SureFit® nozzle connector onto the valve stem. Do not overtighten.
