quiet and strong, January 6, 2012 By llewllyn

QUIET is the operative word on this generator. It easily runs my big Hilti demo hammers
and drills. It does not drive you out of the house due to the noise like some generators.
It is light enough for one person to carry easily and easy to load into a pickup or van.

A Great Low Cost High Power Inverter Generator, April 15, 2011 By James Cothern (Davis, CA)
(REAL NAME)

I purchased this product last fall to be used in the mountains with my trailer in a membership camp ground. Several other units are in close proximity, so I was concerned with noise. This is a GREAT unit. Quiet and runs about 11 hours on 5 gallons of gas and starts on the first pull every time. It has an economy mode which is adequate for most day time uses and is so quiet it can barely be heard inside the unit. When microwaves, air conditioners and other more power hungry devices are used, it automatically accelerates. Tne noise level is higher, and can be heard up to 40 feet from the trailer but it still is relatively quiet. The unit is very light, about 60 pounds, so it is easy to handle by the elderly. I purchased this unit on the recommendation of a camp ground neighbor, who is about 60 feet away. He has been using it for several years and I never ever heard it running.

Beats the Honda hands down, January 28, 2010 By M. R. Reynolds (Tulsa, OK United States)

Good: Can run 12+ hours on a 3 gallon tank of gas. Very clean voltage without the radio frequency hash which you find on a Honda inverter generator. This generator can run my natural gas furnace, some lights, small TV and my main refrigerator without missing a beat. I briefly unplug the refrig. when I want to run my Mr. Coffee. This generator is liftable by one guy. Fits inside a standard car trunk with room to spare. Excellent build quality unlike the junk generators you see at the hardware stores. The Yamaha is much cheaper than the Honda equivalent.

So so: About as loud as your typical lawn mower.

Limitations: Oil fill is a little hard to get to. Not enough power to run my clothes washer or NG clothes dryer but that's no surprise. 12 volt output has a higher voltage than specified so I'll use my 12 volt auto battery charger if I need to charge batterys.

Comment: There is a GFI model and a non GFI model of this generator. I went with the non GFI model to have a more trouble free power source. Your mileage may vary. As I type this review my town is experiencing a typical winter ice storm with lines expected to go down. My Yamaha is fueled up and ready to go with four 5 gallon filled gas cans in reserve.

I test my generator every one to three months or so. It starts on the third pull every time. Exercising a generator plus recycling the gasoline every year will keep you prepared for your next power outage and there will be a next power outage.

I ran a load test consisting of two 1,500 watt heaters drawing a total of 3,000 watts. The generator powered them both for several minutes before the engine stalled. The overload breaker never tripped. Yes I know that the generator is only rated for up to 2,500 watts continuous load. I think that rating is correct.
