Lenmar offers innovative products for consumers and encourages the safe and proper use of each power accessory to
achieve the maximum performance of the product and the devices it powers. Read these instructions carefully to safely
use your new N-Verter product.
Lenmar’s N-Verter is an electronic device that converts low voltage DC (direct current) electricity from a battery to
110/120VAC (alternating current) standard household power. The AC output of this product is a modified sine wave with
a voltage of 110/120 volts. With your Lenmar N-Verter you can power your laptops, computerized games, cell phones,
camcorders, power tools, reading lamps, fans, and more.
Important: Before using your N-Verter, read and understand this owner’s guide. Save these instructions–this owner’s
guide contains important safety instructions.
Safe Operating Guidelines
WARNING! Shock hazard The N-Verter generates the same AC power as a normal household wall outlet.
Operate only in ventilated area away from flammables, flames and accumulating dangerous or explosive fumes
Do not expose unit to water, rain or snow
Always turn OFF unit and disconnect it from power when not in use
Avoid exposure to direct sunlight and extreme temperatures (60-80°F or 15-25°C)
Do not insert foreign objects into the outlet or ventilation slots.
Do not open the unit: no replaceable parts inside
Unit will not and should not operate heat-generating appliances such as hair-dryers, microwave ovens, electric blankets,
toasters, etc.
Compatible only with vehicles that have 12VDC Negative Ground electrical systems
Failure to follow the above may result in personal injury or damage to the N-Verter.
Operating your N-Verter
Connect the bare end of the clip lead cable to the power cable terminals on the N-Verter as shown in figure-2. Be sure to
match the color of the cable ends to the color of the terminals (red to red and black to black) and tighten the screws in
the terminals to hold the cable tightly.
Carefully attach the clip leads to the vehicle’s battery terminals, being very careful not to let the red clip lead touch any
metal other than the battery terminal, and also making sure to observe correct polarity (red to red, black to black).
DANGER! – Do not create a short circuit when working with your vehicle’s power system. Damage to your vehicle’s
internal electronics, explosion of the battery and personal injury may occur. NEVER test for the presence of power by
“sparking” or shorting two wires together.
After the power connection is made, turn the power switch on the N-Verter to the ON position. The green power LED
indicates the N-Verter is powered on and running with power available at the AC outlet(s).
Note: If you are connected to a power block or power source other than the battery terminals, be aware that power may
not be present if the vehicles ignition switch is OFF.
Plug an AC device into either of the three-prong AC receptacles and then turn it on. Ensure your device draws less than
the continuous power rating of your N-Verter. The N-Verter’s internal cooling fan will come on for heavy loads. To avoid
discharging the battery, always disconnect the N-Verter from power when not in use.
If the red status LED is on and the warning tone is sounding, an error condition exists. See the Troubleshooting section
for suggestions on correcting the problem.
Warning - When using you N-Verter with the vehicle’s engine turned off, the battery is being drained. Be careful to
re-start the engine or otherwise recharge the battery periodically to avoid draining the battery too deeply. The internal
“low voltage shut-off” of the N-Verter does not guarantee that the remaining power left in the battery is enough to start
the vehicle.
Warning - Hot surface! The N-Verter housing may become uncomfortably warm, reaching 65°C (150°F) under extended
high power operation. During operation, keep the N-Verter from materials that may be affected by high temperatures.
Attach the cables to the N-Verter unit, being
sure to match the red and black cable ends to
the appropriate color terminal.
