INTRODUCTION
Thank you for purchasing the 750W Power Inverter with
USB Charging Port (PI750LA). This inverter can be
used to operate personal electronics such as: Laptop
computers, digital/video cameras, MP3 players, cell
phones, PDAs, and more. It can also be used to recharge
AC devices that have an appropriate recharging
adapter with a local standard plug. Please read this
Instruction manual carefully before use to ensure optimum
performance and to avoid damage to this product.
FEATURES (Fig. A and B)
1. Positive DC terminal: Connect the red end of the
DC power cord to it.
2. Cooling Fan and Ventilation Openings: The high
speed cooling fan protects the inverter from over-heating.
3.
Negative DC terminal: Connect the black end of the
DC power cord to it.
4. Green LED Indicator: When there is DC power
input, the green LED indicator lights.
5. Red LED Indicator: When the inverter has shut down
because of low or high input voltage, the red LED indicator lights.
6. Button Power Switch: Connect the inverter to the
DC power and press down the button power switch,
the AC power is available.
7. AC Outlets: They allow you to plug in 220V AC
products with a total continuous of 750W or less.
8. USB Port: Offer 5V power to USB equipment.
9. Ventilation Openings: The ventilation openings should
not be covered at any time while the inverter is operating.
10. DC Cable with Clips: Connect the red clip to the positive
terminal of the battery, and the black to the negative.
OPERATING TIPS
The inverter should only be operated in locations that are:
a. Dry: Do not allow water or other liquids to come into
contact with the inverter.
b. Cool: Surrounding air temperature should ideally
be 32°F and 104°F (0°C and 40°C). Keep the inverter
away from direct sunlight, when possible.
c. Well-Ventilated: Keep the area surrounding the
inverter clear to ensure free air circulation around
the unit. Do not place items on or over the inverter
during operation. The unit will shut down if the internal
temperature gets too hot. The inverter will auto-reset
after it cools down.
d. Safe: Do not use the inverter near flammable
materials or in any locations that may accumulate
flammable fumes or gases. This is an electrical
appliance that can briefly spark when electrical
connections are made or broken.
Your 750W power inverter supplies 750W of continuous
power with 1500W of surge power. When you turn on an
appliance or a tool that operates using a motor or tubes, it
requires an initial surge of power to start up. This surge of
power is referred to as the “starting load” or “peak load”.
Once started, the tool or appliance requires less power to
continue to operate. This is referred to as the “continuous
load” in terms of power requirements. You will need to
determine how much power your tool or appliance requires
to start up and its continued running power requirements.
We recommend that the equipment or appliance switch
be in the “OFF” position prior to plugging into the AC
receptacle of the inverter. The green LED light will confirm
that AC power is present.
1. Attach the ring type connector marked with red to the
POSITIVE (+) DC terminal on the power inverter, and
attach the ring connector marked with black to the
NEGATIVE (-) DC terminal.
Caution! Reverse the polarity will arouse blown
fuse or damage to the inverter, which may also be
void of the warranty.
2. Tighten the nut on each DC terminal by hand until it is
snug. Do not over-tighten.
3. Attach the NEGATIVE (black) clip to the NEGATIVE (-)
battery terminal.
4. Attach the POSITIVE (red) clip to the POSITIVE (+)
battery terminal. Make sure both clips are securely
connected to the battery terminals, as a loose connection
will cause the voltage to drop and may cause the cables
to overheat, resulting in equipment damage or fire.
5. Turn on the inverter.
6. When the power inverter is not in use, disconnect the
DC cable clips from the battery to prevent slight
discharge of battery.
OPERATING THE INVERTER
1. When properly connected to a 12V battery, turning on
the inverter, will illuminate the green LED light,
and deliver AC power to the outlet(s).
2. Plug the AC product(s) you wish to operate into the AC
outlet(s) and switch them on, one at a time.
Caution! If there are one more AC products connecting
to the inverter, turn on the larger power product first.
Through its AC outlet, the inverter is capable of powering
most 220V products that use 750W or less. The unit will
operate from input voltages ranging from 11V to 14.5V DC.
As the battery is used, its voltage begins to fall. When
the inverter senses that the voltage at its DC input has
dropped to the range of 10.7V ~ 11.3V DC, an audible
alarm sounds. This allows time for computers or other
sensitive devices to be shut down. If the audible alarm is
ignored, the inverter will automatically shut down when
the voltage dropped to the range of 10.2V ~ 10.8V DC.
