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 N-Verter.
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 by removing it from the DC cigarette lighter outlet 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.
Do not open the unit: no replaceable parts inside
Consult motor vehicle’s manual to determine cigarette lighter socket’s maximum
power rating and fuse rating before attempting use in vehicle.
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.
Special Features:
NVD150S – A swivel tip design allows you to adjust the N-Verter’s position and avoid
interference with the gear shift, cup holders, etc., in vehicles where the DC socket
location causes problems with standard units.
NVD175X – An auxiliary DC socket is provided to allow the use of an additional
12VDC accessory. Be careful that the power requirements of the N-Verter and the
additional DC accessory plugged into the auxiliary socket do not exceed the
maximum power output of the vehicle’s DC socket.
Operating your N-Verter
Plug the N-Verter into your vehicle’s lighter socket. If the socket is too wide and the
plug tip of the unit fits loosely, use the slide control on the plug tip to adjust the
negative connectors and ensure a snug fit. The green LED will light up when power is
present.
Note: Many vehicles remove power from the cigarette lighter outlet when the
ignition key is turned off!
Plug an AC device into the three-prong AC receptacle and then turn it on. Ensure your
device draws less than the continuous power rating of your N-Verter. To avoid
discharging the battery, always remove the N-Verter from the lighter socket when not
in use.
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 aviod 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.
Modified Sine-Wave Output
THE OUTPUT OF THE N-VERTER IS NON-SINUSOIDAL. This type of output can typically
be incompatible with small battery-operated products such as rechargeable
flashlights, some rechargeable shavers, and nightlights that plug directly into an AC
receptacle to recharge as well as certain battery chargers for battery packs used with
power tools. If you wish to use one of these types of items with the N-Verter, monitor
its temperature for the first ten minutes to insure excessive heat is not produced. The
production of excessive heat indicates the device is not suitable for use with the
N-Verter. The overheating does not occur with most devices which use their own AC
adapters. The N-Verter is compatible with most of these chargers and AC adapters.
Troubleshooting
Symptom
Problem / Solution
An AC device is connected
and turned on causing the
N-Verter to shut down
immediately.

unit does not light and/or the
AC device does not operate
Buzzing sound in
audio systems
Television
interference
The AC device has higher wattage demands or requires
a larger start-up surge current than the N-Verter’s
maximum rating can allow. The N-Verter unit is too
small for this device. A higher rated N-Verter is needed
to deliver the power that the AC device demands.
Otherwise, use only lower power AC devices.
On many vehicles, the ignition key must be “on” for
power to be present at the cigarette lighter socket.
Make sure the key is on.
The N-Verter plug tip may be fitting too loosely. Use the
slide control on the plug tip to adjust and ensure a snug
fit and re-insert.
Battery voltage may be too low. Recharge the vehicle’s
battery and attempt again.
Vehicle fuse may be blown. Replace the vehicle’s fuse
with the same type and rating. Make sure you are not
overloading the socket or the fuse will blow again.
Many inexpensive stereos or portable players will buzz
when connected to the N-Verter because the modified
sine wave of the N-Verter is not properly filtered by the
electronic device’s power supply. Higher quality devices
will not buzz with the N-Verter.
If the television signal is weak, the use of the N-Verter
will cause a visual disturbance. Move the N-Verter away
from the TV, antennae and/or the antennae cables. You
may attempt to merely adjust the placement of the
antennae or cables. Inferior antennae and cables will
also cause TV interference during operation of the
N-Verter.
