6. OPERATING INSTRUCTIONS
IMPORTANT! Charge immediately after
purchase and when battery level is below
40%, to keep the internal battery fully
charged and prolong battery life. Do not
recharge unit for more than 12 hours.
POWERING ON
Press the ON/OFF power switch. The unit
will initialize, and all icons on the LCD
screen will activate. If normal function
is detected, the screen will return to its
normal display.
CHECKING THE LEVEL
OF THE INTERNAL BATTERY
The Battery Capacity Indicator on the
LCD display will show the battery’s charge
level in 20-percent increments. For best
performance, the battery capacity should
be 20% or greater.
CHARGING THE INTERNAL BATTERY
NOTE: Do not use the unit while charging
its internal battery.
AC adaptor
1. If the red AC Output LED is lit, press
the AC Output button to turn off before
charging.
2. Connect the provided AC charger to
the socket on the front of the unit. Plug
the charger’s power cord directly into
a live grounded 120V outlet. Charging
will start automatically, and the AC
Adaptor Charging icon will show on the
display.
3. While the unit is charging, the rotating
Charging indicator will show on
the display. When the internal battery
is fully charged, all ve bars of the
Battery Capacity indicator on the
display will show. Complete charging
will take approximately 5 hours.
4. When the unit is fully charged, unplug
the charger from the 120V outlet and
then from the unit.
Solar Charging
Solar charging can be accomplished by
plugging in a 30-36V solar panel (not
included) into the Solar Charging Input port.
The Solar Charging icon will show on
the display. For best results, face the panel
toward the sun, away from curtains and
windows. Charging by solar panel takes
approximately 10 hours (on a sunny day).
POWERING A 12V DC DEVICE
NOTE: Do not power a 12V device while
charging the internal battery.
12V DC Output
1. Make sure the device to be powered is
OFF before inserting the 12V DC plug
into one of the two 12V DC output ports.
2. Plug the 12V DC device into one of the
12V DC output ports and turn on the
12V DC device (if required). The
12V DC output icon and the rotating
Discharging indicator will show on the
display.
3. When nished, turn off the DC device
(if required) and unplug from the DC
output port.
4. Recharge the unit when the battery
level is below 40%.
12V DC Cigarette lighter plug
1. Make sure the device to be powered
is OFF before inserting the 12V DC
cigarette lighter plug into the 12V DC
cigarette lighter socket.
2. Plug the 12V DC device into the DC
cigarette lighter socket and turn on
the 12V DC device (if required). The
Cigarette Lighter Output icon and the
rotating Discharging indicator will
show on the display.
3. When nished, turn off the DC device
(if required) and unplug from the DC
Cigarette Lighter socket.
4. Recharge the unit when the battery
level is below 40%.
USING THE USB PORTS
The USB ports provide 1A, 2A and 2.4A
at 5V DC.
1. Plug the device into one of the three
USB ports on the front panel.
2. Turn on the USB device, if necessary.
The USB Output icon and the
rotating Discharging indicator will
show on the display.
3. When nished, turn off the USB device
(if required) and unplug from the USB
port.
4. Recharge the unit when the battery
level is below 40%.

USING THE LIGHT
There are 5 lighting modes:
•High (100% power)
•Normal (50% power)
•Energy saving (25% power)
•Emergency ash
• SOS
Press once to turn the light ON or OFF.
Press twice quickly, to change to the
next mode.
USING THE AC POWER OUTLETS
The SL1404 is equipped with a 500W pure
sine wave inverter, which produces the
best power for all electronic devices and
appliances, without damage.
It is important to know the continuous
wattage of the device you plan to use with
the AC outlets. The unit must be used with
devices drawing 500 watts or less.
Devices such as fans or electric motors
require additional power to start (commonly
known as the “starting” or “peak” power).
The generator can supply a momentary
surge in wattage of as high as 2,500W
for less than 1/10 of a second; however
even devices rated less than the maximum
500 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 erratic
operation.
CAUTION: 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 (noted
with an audible alarm beeping every 3
seconds and a ashing Warning icon),
the inverter is designed to automatically
shut down. This safety feature prevents
damaging the inverter while testing devices
and equipment within the 500-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.
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 16 AWG (1.31 mm
2
)
or larger and no longer than 50 feet.
WARNING! RISK OF ELECTRIC SHOCK.
Incorrect operation of your inverter may
result in damage and personal injury. The
inverter output is 110V AC and can shock
or electrocute the same as any ordinary
household AC wall outlet.
NOTE: The maximum continuous load
is 500 watts. Do not use the AC outlets with
a product that draws more than 500 watts,
as this may cause erratic operation.
CAUTION:
• Do not connect an AC power source to
the 110V AC outlets.
• Do not connect the unit’s AC power cord
to its 110V AC outlets.
NOTE: Do not power an AC device while
charging the internal battery.
1. Connect your AC-powered devices or
small household appliances to one or
more of the unit’s two AC outlets.
NOTE: Make sure the device to be
powered is OFF before inserting the plug
into the AC power outlet.
2. Press the AC Output button. The AC
Output icon will show on the display
and the green AC power LED lights,
to conrm that the unit is on and ready
to provide AC power. The rotating
Discharging indicator will also show on
the display.
NOTE: Extended operation of an AC device
may result in excessive battery drain.
3. Recharge the unit when the battery
level is below 40%.
