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 750 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 use 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:

Switch Mode Power Supplies;

1. 

Linear Power Supplies;

2. 

Class 2 Transformers;

3. 

Line Filter Capacitors;

4. 

Shaded Pole Motors;

5. 

Fan Motors;

6. 

Microwave Ovens;

7. 

Fluorescent and High Intensity Lamps (with a Ballast); and

8.
