1. Introduction Thank you for purchasing the NPower 750W Power Inverter, a high performance solution to use household power while on the road. Connected to the 12V volt output in your vehicle, the inverter efficiently and reliably supplies 110V/60Hz AC power for a wide variety of loads, such as all kinds of jacklights, TV sets, audio/video systems and electromotion tools with power consumption under 750 watts. It has been tested and found to be in line with the requirement of ETL certification.
Warning！ The case to the unit may become very warm under high power operation reaching 140°F(60°C). Be sure that there is at least 2 in (5cm) of unobstructed air space around the entire surface of the inverter at all times. During use, do not place materials that could be damaged by heat near the unit. Warning！ Do not operate the unit near flammable fumes or gases such as the cabin of a gasoline power boat, or near propane tanks.
Certain battery chargers for battery packs used in hand power tools. These chargers will have a warning label indicating that dangerous voltages are present at the battery terminals. Caution！ Connect the unit to batteries with a normal output of 12V DC only. As 6V batteries voltage is too low, and a 24V battery voltage is too high which will damage the unit. Additional Safety Guidelines！ Do not insert any foreign objects into the unit outlets, vents or fan openings.

AC Outlets— They allow you to plug in 110V 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.

Do not operate the unit in the same compartment as Safe batteries or in any compartment capable of storing flammable liquids like gasoline. Do not operate the unit in an area that is prone to dirt, dust Clean or debris. Especially important if used in a work environment. Your 750W Power Inverter supplies 750 watts of continuous power with 1500 watts 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.
cables to overheat, resulting in equipment damage or fire. 5) 6) Turn on the inverter. When the power inverter is not in use, disconnect the DC cable clips from the battery to prevent slight discharge of battery. 5. Operating the inverter 1) When properly connected to a 12V outlet or 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.
extended periods of time, you should consider connecting the unit to a separate deep discharge battery. Should a defective battery charging system cause the battery voltage to rise to the range of 15.0V~16.0VDC, the inverter automatically shuts down; and the red LED lights. Caution！ If there are one more AC products connecting to the inverter, turn on the larger power product first. If an AC product rated higher than 750W (or which draws excessive surge power) is connected, the inverter will shut down.
Buzzing and in audio systems and radios Some stereo systems and AM-FM radios have inadequate internal power supply filtering and “buzz” slightly when powered by the inverter. Generally, the only solution is an audio product with a higher quality filter. Television interference The inverter is shielded to minimize its interference with TV signals. However, with weak TV signals interference may be visible in the form of lines scrolling across the screen.
