To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x wattage.
In general, the startup load of the device or power tool determines whether
your converter has the capability to power it.
Always run a test to establish whether the converter will operate a particular
piece of equipment or device. In the event of a power overload, the converter
is designed to automatically shut down.
This safety feature prevents damaging the converter while testing devices and
equipment within the wattage range of the converter.
IMPORTANT: This converter is designed to power 100 watt devices or less
when used with the vehicle’s 12 volt accessory port.
NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles.
Some vehicles may allow the full output. To use the full output, you must
purchase a 12 volt accessory outlet-to-battery battery clips adapter and
connect the inverter directly to the battery. If the fuse blows when you switch
on the device you are trying to use, you must either use a smaller device or
the battery clips adapter.
IMPORTANT: This converter uses a modied sine waveform (diagram A)
which is not quite the same as power company electricity (diagram B). For the
following devices, we strongly recommend that you use caution and check the
device’s manual to make sure it is compatible with modied sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line lter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers
Using the converter with any of these devices may cause the device to run
warmer or overheat.
