Operating Instructions
1. With Inverter’s Switch off, plug 120 VAC
device(s) into the receptacles. Switch all devices
off. The devices must not use more than the
rated wattage during continuous operation,
otherwise they may overload the Inverter.
2. Plug USB device(s) into the USB
port(s). Switch all devices off.
3. Turn the Inverter’s Switch on.
NOTE: Some rechargeable devices may
damage the Inverter or the device(s).
When first using a rechargeable device,
check the Inverter’s temperature for the first ten minutes.
If it becomes abnormally hot,
do not use the device with the Inverter.
4. Turn the device(s) on, one at a time.
If the alarm sounds, turn off the device(s).
Unplug the device(s) from the Inverter.
Check the wattage of the devices, if there were
multiple devices plugged in, discontinue use of
one or more. If a single device sets the alarm off,
it is not appropriate for use with the Inverter.
5. If the Inverter is powered by a vehicle’s starting
battery, be careful not to discharge the battery
to the point that it will no longer start the engine.
If needed, operate the engine periodically to
maintain the battery’s charge. Do not operate
a vehicle’s engine in an enclosed space.
6. When the Inverter is switched on, the LCD on the top
of the unit will display the current state of the Inverter.
Output Power
(indicating full power)
Battery Voltage
a. The Output Power graph displays the Inverter’s
current power output. The line below it indicates
the current output voltage of the battery.
The below indicates the Inverter’s power output
is low and the battery is supplying 12.5 V.
b. If a problem is detected by the Inverter,
shutoff messages will display:
• If an Overload/Hi Temp Shutoff message
displays, turn plugged in devices off one
at time. If turning off a device or group of
devices resolves the problem, discontinue
its/their use. If the problem does not
resolve after turning off all devices, turn
off the Inverter and unplug all devices.
• If a Low/Hi DC Shutoff message displays,
turn off the Inverter and unplug all devices.
Disconnect and check battery.
7. Inverter will consume some power while on, even
without loads attached. Turn Inverter off after use.
