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.
When using the vehicle's 12 volt accessory port, this
inverter is designed to supply 60 to 70 watts when the vehicle is
not running. With the vehicle's engine running, it can supply up to
100 watts. To use the full output, you must connect the inverter
directly to your battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings
for all vehicles. Some vehicles may allow the full output. If the
fuse blows when you switch on the device you are trying to use,
you have to either use a smaller device or you must 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:
1. Switch Mode Power Supplies
2. Linear Power Supplies
3. Class 2 Transformers
4. Line Filter Capacitors
5. Shaded Pole Motors
6. Fan Motors
7. Microwave Ovens
8. Fluorescent and High Intensity Lamps (with a Ballast)
9. Transformerless Battery Chargers
Doing so, may cause the device to run warmer or overheat.
