The wattage (WATTS) or amperes (AMPS) can normally be found stamped or
printed on most devices and equipment, or in the user’s manual. Otherwise, contact
the manufacturer to find out whether the device you want to use is compatible with a
modified sine wave.
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x WATTS. In general, the start up
load of the device or power tool determines whether your inverter has the capability
to power it.
To calculate the continuous load: Continuous Load = AMPS x 120 (AC Voltage).
Always run a test to establish whether the inverter will operate a
particular piece of equipment or device. In the event of a power overload, the inverter
is designed to automatically shut down. This safety feature prevents damaging the
inverter while testing devices and equipment within the wattage range of the inverter.
If a device does not operate properly when first connected to the inverter, turn
the inverter ON, OFF, and ON again in quick succession. If this procedure is not
successful, it is likely that the inverter does not have the required capacity to operate
the device in question.
This inverter is designed to power 100 watt devices or less when
used with the vehicle 12 volt accessory port. To use the full 400 watt output you must
use the battery clips adapter and connect the inverter directly to the battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles. Some
vehicles may allow the full output. If the vehicle’s fuse blows when you switch on the
device you are trying to use, you have to either use a smaller device or the battery
clips adapter and connect the inverter directly to the battery.
This inverter uses a nonsinusoidal waveform. Therefore we do not
recommend you use it to power the following devices:
