lighter socket, make sure the socket and plug are clean,
then reconnect it.

3. Set the inverter’s switch to

 (on). The power switch’s indi-

cator lights.

4. Plug the desired device’s AC plug into one of the inverter’s

AC sockets. You can connect one or two AC plugs to the
inverter.

Note: If necessary, you can use an AC extension cord. The
extension cord’s rating should be equal to, or greater than,
the current rating (amps) of the device being powered.

5. Turn on your device’s power as you normally would.

6. When you are not using the inverter, flip its power switch to

 (off).

Powering Devices with a Power Rating of 140 to 
300 Watts or More

1. Align the rectangular locking tab on the alligator clip cord’s

plug with its matching groove on the inverter’s connector,
then press the plug and connector together until they click.

2. Clip the red alligator clip to the vehicle battery’s + terminal

then clip the black alligator clip to the vehicle battery’s – ter-
minal.

3. Set the inverter’s switch to 

I

 (on). The power switch’s indi-

cator lights.

4. Plug the desired device’s AC plug into one of the inverter’s

AC sockets. You can connect one or two AC plugs to the
inverter.

Note: If necessary, you can use an AC extension cord. The
extension cord’s rating should be equal to, or greater than,
the current rating (amps) of the device being powered.

 (off).

AUTOMATIC SHUT-OFF

Your inverter automatically shuts off under certain conditions. If
your inverter shuts off, follow these recommended solutions to
restore operation. 

LOW BATTERY ALARM

When the inverter’s input voltage decreases to lower than
about 11 volts DC, it sounds an alarm indicating the connected
vehicle battery is weak. Stop operation immediately.

When the input voltage decreases to lower than about 10 volts
DC, the inverter’s output cuts off to prevent battery power drain-
age. 

REPLACING THE FUSE

If you accidentally connect the inverter to a battery’s terminals
incorrectly or the inverter does not operate, you might need to
replace the 30-amp blade-type fuse on the inverter’s back pan-
el.

Caution: Do not use a fuse with ratings other than those speci-
fied. Doing so might damage your inverter.

1. Grasp the fuse’s plastic end and pull it out of the back of

the inverter.

2. If the fuse is blown, replace it with the supplied spare 30-

amp fuse.

3. Grasp the fuse’s plastic end and push it in.

Condition

Solution

Device being powered 
has a short circuit. 

Unplug the device. If the inverter resumes 
normal operation, the device being powered 
is faulty.

Temperature exceeds 
158

°

F (70

°

C).

Disconnect the device and wait until the 
inverter cools. The device’s power require-
ment might exceed the inverter’s rating (see 
“Heat Dispersal”).

Power load exceeds 
380 watts.

Disconnect one or both of the connected 
devices. Only connect devices with a power 
load of less than 380 watts.

Vehicle battery volt-
age is lower than 10V.

Run the vehicle’s engine to recharge the bat-
tery, then turn the inverter’s power switch off 
and on.
