300 Watt DC to Dual Outlet AC Power Inverter
Your RadioShack 300 Watt DC to Dual Outlet AC Power Invert-
er converts 12-volt vehicle battery power into 115 volts of AC
power. You can use the inverter in your vehicle to operate
many types of appliances that use AC power such as TVs,
VCRs, portable computers, power tools, and lights for emer-
gency or camping use.
The inverter works with your vehicle’s engine turned on or off. It
provides a continuous output of up to 300 watts, and sustains a
temporary output of 340 watts for approximately 5 minutes. It
can “cold start” a load of up to 380 watts.
Caution: Do not use the inverter in a positively grounded vehi-
cle.
600W Peak Power — lets you use the inverter to power appli-
ances that require a large amount of initial (peak) power to
work (such as many personal computer monitors and TVs).
Low Battery Alarm — the inverter sounds an audible alarm
then turns itself off if the source battery becomes too low.
Auto Shutdown/Reset Protection — the inverter temporarily
shuts itself down to protect itself from overheating, and restarts
automatically when it cools.
Reverse Polarity Protection — the inverter’s built-in fuse
helps protect the inverter if you accidentally connect it to a bat-
tery the wrong way.
Overload/Short Circuit Protection — the inverter automati-
cally turns itself off if the connected load is too high or it shorts,
alerting you to unplug it or correct the short.
Auto TV Starting Circuit — lets you use the inverter to power
personal computer monitors and TVs more easily.
Two 30A Fuses Supplied — the inverter comes with one fuse
already installed, as well as a spare fuse.
Dual AC Outlets — let you use the inverter to power up to two
appliances at the same time.
HEAT DISPERSAL
The inverter generates heat while it is working. This is not a
malfunction. However, if the inverter gets too hot while working,
it will turn itself off.
Position the inverter where air flows freely around it to allow the
heat to disperse.
The inverter’s thermal protection prevents it from operating
when its temperature exceeds 158
°
F (70
°
C). Operation re-
sumes when the temperature decreases to about 104
°
F (40
°
C).
CONNECTING POWER
Your inverter comes with two types of connection cords. Deter-
mine the type of appliance that you want to power, then follow
the appropriate steps below.
Important:
• If you are powering a device with a power rating of 140
watts or more, you must connect the cord with the alligator
clips to the inverter. Otherwise, connect the cord with the
cigarette-lighter plug to the inverter.
• The inverter’s built-in fan runs at high speed when you turn
on the inverter. If it runs slowly or stops, immediately dis-
connect the inverter from any power source, then take it to
your local RadioShack store.
Powering Devices with a Power Rating of Less
Than 140 Watts
1. Align the rectangular locking tab on the cigarette-lighter
cord’s plug with its matching groove on the inverter’s con-
nector, then press the plug and connector together until
they click.
2. Plug the cigarette-lighter plug into the vehicle’s cigarette-
lighter socket.
Cautions:
• The cigarette-lighter plug might get warm while it is
plugged into a cigarette-lighter socket. Unplug it from the
socket and let it cool completely before you store it.
• Using a dirty cigarette-lighter socket might cause your
vehicle’s battery to discharge below 10 volts. If you can-
not turn on the inverter, unplug it from the cigarette-
