Received delivery of this generator on the day of a huge storm that swept through and knocked out power for 30 hours. This generator allowed me to pump out my full sump pit, keep my two fridges cold, and had the TV and fan running (all happened at separate intervals).

The best thing about this generator is how easy it is to use, and it's only 70 lbs. Fill up with gas and oil, switch the power on, gas on, choke, and pull. This generator is so quiet and has plenty of power to get you through a short term power outage.

Dollar for watts, this is the best inverter generator out there. If I ever need a 30 amp hookup (ie. for a transfer switch connected to a house panel), I can buy another one of these generators and set up a parallel hookup. Also, since it's lightweight and quiet, I can use it for other purposes like camping. I also bought the hour meter and cover.

This is a quality piece of equipment, made in Japan. Not the Harbor Freight special.

Bought it to power our travel trailer AC which it does with no problem. Bigger fuel tank with gauge runs for ~7 hours. Have used it in power outages to run the house refrigerator, freezer, lights, computer, wood stove fan and TV. Easily paid for itself by keeping the freezer food frozen and the refrigerator running on one outage. Fits the front rack of the fourwheeler and powers portable tools, air compressor, hair clippers at the barn and around the farm. Been using for 5 years without a problem. Very quite. Two handles makes it easy to carry.

I purchased a Homelite 1800 from Home Depot. This gen was spec'd out about the same as the ef2400is. The Homelite was dimensionally samller then the Yamaha. Besides price that was the only win for the Homelite. The Yamaha is quieter and noticably better built. The engine on Homelite was a subaru which are fairly quite but still no contest between the two. I took the Homelite back to Home Depot and purchased the Yamaha. Main reason for switching to the Yamaha is the ability to start my 13,500 btu AC on my Trailmanor 2720. After starting the Yamaha several times I am really happy with the purchase. You do not have to pull the chord very much at all before is starts, and it only takes 1 pull.

I purchased a Yamaha 2400ishc inverter generator through Amazon and we are delighted with the service and the performance. The generator was purchased from SW trading in Utah and arrived early. Upon taking it out of the box I oiled and gassed it, turned on two switches, set the choke, pulled the recoil starter and the engine sprang to life, and quietly too.

We have a 33 foot travel trailer with a Dometic 13,500 BTU rooftop AC unit. At first the Yamaha would not run it but after some research I found that by installing a $25 hard start capacitor on the AC unit everything worked perfectly. I am writing this from within my RV in 90 degree heat and the Yamaha is quietly purring behind me while the temperature inside is 78. The only items I cannot use with the AC on are the mocrowave or a hair dryer, otherwise everything will work while the AC is running including the TV, hot water heater, water pump, battery charger for my electric scooter, this computer and all the lights. You can't do better than that for the money.

Last night a fellow camper came to our door and asked if we knew the people in the rv next door because their "loud" generator was keeping him up. I said no, but my Yamaha is running and I will turn it off if you want me to. He responded by saying the Yamaha was fine, it was the Honda that was too noisy. Go figure, the Yamaha is 400 watts more powerful than the Honda.

By the way, if you decide to purchase a Yamaha 2400is, be sure it is an ISHC. THE HC is the newest model and the one most likely to run a 13,500 AC unit.

I had been looking for a generator for my camper that could start and run my 13,500 btu A/C, this one does with no trouble at all. I have had it for 6 months now and used it several times during power outages, once was for 55 hrs streight, it powered my refegerator, freezer, satalite dish, 2 LCD flat screen tv's (50+") computer, two electric blankets (these only took 180 watts each), fish tank and one light and would run for over 7 hrs on one tank, i couldn't get it to run all that and a toaster oven and i didn't try the microwave. I couldn't hear it over my two neighbors with there noisy non-inverter style gens.

Have owned the Yamaha 2400 for about 4 years now. Bought the optional hour meter at the same time. I have logged 1825 hours so far. Yes, it starts my 13,500 btu RV air conditioner. (Has $25 hard start kit). 1825 hours is much more than I have ever seen on any brand. This generator is probably run much harder than you will ever run it. It is used at the dunes (near Death Valley) and various dry lake beds, forests, deserts, ect. We are into off road racing. It has been used in dust storms, sand storms, rain storms and snow storms. Always starts first pull, and has never had any extra maintenance besides that stated in the owners manual. The only work I have ever had to perform as a repair was after a terrible all night sandstorm at Dumont dunes,a grain of sand got lodged in the electronic throttle control and caused a high idle. Blew it out with an air compressor and was good as new. Have never had a noise complaint.

Now for the load test. After one thousand, eight hundred, and twenty five hours, I took all the covers off. Blew everything out with compressed air. Removed carb. Cleaned carb, but really found nothing wrong. Blew out cooling fins on the motor. Checked valve adjustment (needed no adjustment) put back together, changed oil. Warmed up and increased load to 18 amps. This generator is rated at 16.7 but has no problem holding 18. No oil burning or leaks. ready for 1825 hours more.

This generator replaced the Honda. Have never regretted the decision. If you are in the market, don't hesitate. Just buy it, you will be glad you did.

I bought the 2400ishc for camping. This does start my 13500 BTU A/C no problem. Very quiet, perfect for camping.
