If you know your amp demand? take the Watts you think you need? divide it by the voltage you actually need 125 or 240 & you will have the Amps Number the generator can provide... WATTS DIVIDED BY VOLTAGE IS WHAT THE GENERATOR CAN PROVIDE IF IT IS 100 PERCENT DUTY CYCLE GENERATOR....... If it is the correct size gererator.Make sure you are buying a 100 percent duty cycle Generator if it is for Emergency Use.... This means you can pull max amps constantly. The Cheaper Generators are actually 60 percent duty cycle units. This means in a 10 min interval you can pull max amps for 6 minutes & then for 4 minutes you must get completely off the demand. Or you must Decrease the amp draw all together by 40%.... Point is a CHEAP Model Generator will never pull its wattage of any length of time they are Overrated Big Time... If you read the Fine print they are 60% duty cycle Generators. Not 100% duty cycle like a Honda or Yamaha. There is Nothing better than the Inverted Honda Generators. being they are inverted you can put them in the Conserv mode & they sense the actual Amp demand & Slow the engine RPM down to save fuel & meet the amp draw at the same time.....HONDA Inverted generators are the Way to go if you can afford one. Treat the gasoline or keep the gas tank & carb empty if you need only for emergency use......
