Thank you for purchasing Smart AC® 150 USB+™ by Wagan Tech®.
With normal care and proper treatment it will provide years of reliable
service. It is important to read, understand, and comply with these
instructions before using this inverter. Keep this User’s Manual for future
reference.
General Information
This inverter is powered from a 12 volt DC source and provides 110
volts to 120 volts AC 60 Hz through two North American standard
outlets to AC appliances up to 150 watts. The AC waveform is a
modified sine wave (MSW) which approximates the sine wave of
household electrical service. An attached DC power cord connects to a
12 volt DC cigarette lighter socket. There is a USB power port that can
be used to charge tablets and e-readers, cell phones, smart phones,
digital cameras, and other USB electronics. Safety features include
automatic shutdown in the event of overheat, overload, under voltage,
and over voltage conditions.
This inverter has features that will prevent your battery from being
completely discharged. An audible alarm will sound when the battery
voltage is 10.5 volts. If you hear this alarm we recommend operating
your engine for 10-20 minutes to recharge the vehicle’s battery.
WARNINGS
• Keep the inverter away from children.
• Do not operate the inverter with wet hands because of electrical
shock hazards.
• This device produces a voltage similar to wall outlets at home and
should be treated with the same caution.

Operating Environment & User Responsibility
• Unplug the inverter when starting the vehicle’s engine.
• Unplug or disconnect the inverter when it is not in use.
• Keep at least one inch of clearance around the inverter for air
flow.
• Keep the inverter and all cords dry.
• Secure the Inverter to keep it from changing position while a
vehicle is moving.
• Know the wattage requirements of your appliances. Appliance
total wattage can not exceed 150 watts.
• Make sure the inverter is connected to the correct voltage and
polarity.
• Do not connect the inverters AC output to another AC power
source. Damage will result, voiding the inverter’s warranty.
• The 12 volt supply must provide between 10 volts to 14.5 volts
DC.
• Do not use an extension cord between the DC power source
and the DC input of the inverter. An extension cord can create a
voltage drop that can reduce efficiency and output.
Verify the fuse size of your vehicle cigarette lighter socket. If the fuse
is a 10A fuse, your output will be limited to 120W. Most recent vehicle
models come with 15A fuses.
For Power Cord with Cigarette Lighter Adapter Installed:
i. Insert the DC plug into the vehicles accessory socket.
ii. Turn the ignition switch to the accessory position, if necessary.
iii. Insert appliance plug(s) into AC socket(s) at the front of the
inverter.
iv. Turn on the power switch that is located on the front of the
inverter.
v. The green LED will light to confirm that AC output is present.
vi. After use, turn OFF the inverter and disconnect the plug from
the accessory socket.
USB Power Port
When the inverter is powered on, the USB Power Port provides
5 volts DC up to 2.1 Amps for charging tablets and e-readers,
cell phones, mp3 players, and more. (Charging/power adapter cord not
included.)
Follow the instructions below to power the inverter.
i. Connect the device to the adapter cord.
ii. Plug the USB connector into thee USB Port.
iii. Turn on the device.
iv. After use, turn off the device and turn off the inverter.
v. Disconnect the USB connector from the inverter.
vi. Disconnect the inverter from its power source.

Note for Vehicle Use
This inverter has features that will prevent your battery from being
completely discharged. An automatic shutdown will initiate when the
battery voltage is 10.5 volts. If this occurs we recommend operating
your engine for 10-20 minutes to recharge the vehicle’s battery.
CAUTION
• If you use a battery charger to recharge your battery, be sure to
disconnect the inverter first. Failure to disconnect the Inverter prior
to connecting a charger may result in an input voltage spike that
can damage the Inverter.
• Powering this inverter with greater than 15 volts DC can damage
the inverter and void the warranty.
• Do not use an extension cord between the DC power source and
the DC input of the Inverter. An extension cord on the DC input
can create a voltage drop that can reduce efficiency and output.
• Do not open the case of the inverter. There are no user
serviceable parts inside.
• Do not let the cord of the inverter or any appliance cord get
wet. Do not operate this Inverter in or around water. Water
can damage the Inverter. Water damage is not covered under
warranty.
