Good generator, but a little heavier than expectedReview by Fred
Value
Quality
The product lit says 70 # but the package says 90#. I haven't put it on the scale, but I'd say it's closer to the latter.
I've looked for a while, but this is the only generator that seems to make sense for RV use if you need to use the AC. I see generators that deliver 3 times the power for less than half the price but they're also three times the weight! I don't understand why the higher price, except that there seems to be no competition.
Oil a little tricky to add. The instruction booklet shows a small canister with a spout. Haven't found anything that remotely resembles the drawing, so I used a small funnel which makes it a 2 handed process! Come on Yamaha...include a plastic cup with the oil measure marked!
That said, it started with the FIRST pull! Ran without a load for a spell, then connected to trailer and tried various appliances without a problem. Then tried the AC. It didn't work the first time, so I disconnected the Generator, connected to house power, ran it, then tried the Yamaha again and it worked!
Wise sales processed my order and shipped it the next day. I would have had it in 3 days but for an issue with Fedx Ground....had to pick it up to finally get it! (Posted on 8/21/14)

I received it in a short time. Oiled and gassed it up. Let it run for 45 min no load. Fired up on first pull, amazed me. Hooked it up to fifthwheel. It barley even idled up then idled right back down. Lights converter charger didn't even phase this thing. Turned on 13500 btu ac and it idles up a little louder but not as loud as ac fan. I'm so happy it runs my ac. Now were ready to go off the grid. Awesomely engineered machine!! Thank you WISE SALES for the extra year warranty. (Posted on 3/31/14)

I am exceptionally pleased with the dealer, Wise Equipment. The Generator arrived quickly and incredibly well packaged. It took me a bit to find the time to test it out after I unpacked it. However, once I did, I was astounded by the quietness of this generator. To my ear, it is MUCH quieter than my HONDA EU2000i which I also like very much. What the Yamaha lacks in portability, it more than makes up for in the oomph it provides in a pinch. I've mounted it on a mover's dolly and I have no problems moving it around. It powers up my back-up fridge and two freezers all at the same time, no problems. I was too "cheap" to spring $12k for a whole house genset, but I am pretty well prepared for the occasional power outage with my Yamaha EF2400 plus my Honda EU2000i. Thank you, Wise!

Shipping time was fantastic, wish I could get stuff shipped out that quick! Came a day earlier than originally promised. Double boxing was great , no damage what so ever. Started right up, I ran it for a hour charging a battery then took it over to my R/V and started it up, I had accidently left the AC on high instead of off ! When I plugged the R/V cord in it bogged down for just a second and I said OH NO, but it picked right back up and was not running hard, went inside and the AC was running and cooling! Amazing that it started that load from cold! It uses much less fuel than I thought it would, it runs the Microwave ,TV, AC and Frig all at the same time and don't seem to be under much load.
I believe that people who have trouble with them not running there AC are using to small a power cord or one too long.
I am totally satisfied and would recommend it to anyone! (Posted on 9/28/13)

Recieved overnight shipment and packing was excellent. Added oil and fuel started the unit first pull. I have a 2012 popup with coleman mach 13500 ac unit that runs on a 100 foot 14 ga extension cord and a 15 amp breaker that runs the ac unit. When I connected the new generator I was very upset when it would not start my unit. Thinking maybe the outputs of the unit needed to be parrelled I called the tech support of wise equipment. I was told no, each duplex should have the 16.7 to 20 amp output. When I explained what I had I was told the unit must be too small. I was told I could return it but that defeats the purpose of why I had this one sent overnight. I needed it for this week end. (Posted on 8/29/13)

Weighs half what my friends Honda 3000 is and yes, I had a Honda before (a 2000) and loved that unit but it could not start an AC unit. (Posted on 8/1/13)

Originally bought this generator to power my RV. Very capable of running the 13 BTU air conditioner and all other basic electronics in my 25 foot travel trailer without straining. Gas consumption is great. 7-8 hours of run time. Then, during Hurricane Sandy, the unit really came in handy. It ran for about 14 days straight, 24 hours a day. Ran the house refrigerator, lights, electronics and small heater, just purring along, allowing us to sleep without the noise of a contractor generator. You get what you pay for. Unit ran so great, my brother and my brother in law both have one now. (Posted on 2/20/13)

I have both, I have owned the honda 2000 for 4+ years and I just got the Yamaha,
with no load I think the yamaha is slightly louder, however under high load I believe the Honda is louder, I don't have an audio meter so I cant verify this just my impression. the honda 2000 is definitely more portable so if you dont need the extra power go with the Honda (lower fuel demand also), Both will run the AC on my toy box, but i am sure the yamaha will last longer with the high load as It barely changes rpm with the load.

I placed the order on a Tuesday morning and the generator was at my door on Thursday morning. It arrived in perfect condition. I added oil and gas and it started on the 1st pull.

Pricey But The It's The Best Review by Flail
Value
Quality
My family just bought a travel trailer and we set a goal to find a generator that allowed us to power it while dry-docking or staying in a campground that had no electricity. We wanted it to run all of our needs while camping and be efficient and quite. After exhaustive research I decided to go with the 2400ISHC. I purchased the generator from Wise and was impressed with the overall experience. After firing it up I soon realized that after all the cyber descriptions I had finally got to see and hear it for myself. All the great reviews are accurate. It is a workhorse and it is very quite. My friend has the Honda EU2000iA and I was impressed with how quiet it was. Now I have to say that at standard load, the Yamaha is quieter. Although I did not use it with my AC, there was nothing that I threw at it that it didn’t handle.

I guess it is only fair to state my opinion about the cons. For one, it is expensive. It was hard to justify the price UNTIL you see it in action. Also, it would be better if there were some place you could secure it to the frame for theft protection. If you wrap a chain around the handles, taking out a simple bolt is all you would need to steal it. I ended up drilling a hole through the steal frame portion that the handles attach to and strung a master lock python through it.

Other than those two cons, I have nothing negative to say about this unit. It out performs the Honda by that 5% and that was enough to satisfy me.

Took delivery on the Yamaha EF2400iSHC the other day. Added oil and gas, it started on the first pull. Just purrs at idle, not much louder with a 5000BTU AC or 18 cu. ft. fridge (except at start up), and runs either one and a 1/3HP sump pump at the same time. Obviously, you can go to Home Depot and get something with a lot more power for a lot less money. However, they tend to be LOUD, less efficient and unsuitable for running a computer or modern TV, all of which should be a consideration if you might be without power for a few days. I swallowed hard at the price tag, but it was definitely money well spent. (Posted on 1/7/12)

I have both the Honda 2000i and just recently bought this Yamaha 2400i. The Honda is nice and portable, whereas this Yamaha is a little larger & heavier, however the Honda WILL NOT run my A/C on my travel trailer, this Yamaha WILL run my A/C & Refrigerator at same time. I have no complaints what so ever with this generator. This Yamaha makes exact same amount of noise as my Honda so do not think because its bigger it will be louder as it is not. (Posted on 1/7/12)
OUTSTANDING GENERATORReview by CAMPING NUT

I have now owned my Yamaha EF2400is for 4 years and it has served me well. Here in western Washington we get some serious windstorms that knock out power for days. This generator runs and runs, automatically adjusting to changes in load, and does it quietly. With a light load, this generator will run for 9 hours before you need to refill it, which means a night of uninterrupted sleep. Put in some gas, pull the handle once or twice and you are good to go. I highly recommend this product. (Posted on 1/7/12)

Gen set arrived in good condition--well packed. After adding oil and fuel it started on the first pull. Very quiet at idle. After letting it run for 1/2 hour, I connected my 30 amp RV cord and turned on our Coleman High Efficiency A/C which draws only 10.2 amps. The Yamaha started and ran the A/C with no problem at all, and I was surprised that the rpm/noise level was not much higher than with no load. Ambient temp was 72 degrees. Based on this first impression, I believe it will be able to run the A/C at the same time the converter is doing full charging of the batteries. Will have to wait for spring to determine that. Highly recommend this product. (Posted on 11/29/11)

This I believe is because it has no Eco switch override. Both tools will run after a brief stall I just hope that will not damage the power tool. Might have to look into soft start models of the previously mentioned tools. (Posted on 11/4/11)
Excellent choice for RV powerReview by Wildelk

2400iSHC works great with my Coleman Mach 3+ 13500 BTU air conditioner. Had to install the SPP6 Hard Start capacitor, my Fleetwood Orbit didn't have one at all and the AC couldn't get going.

After installing the SPP6 (Amazon or Grainger has them $16-28) the generator barely raises the RPM's to start the AC and it runs just fine. With the AC not running it has no problem with the microwave and anything else in the trailer.

Mine did ship with one of the plastic tabs on the front shroud broken, I will give Wisesales a call and see what they can do. (Posted on 10/28/11)

Best $$ value for outputReview by JBHUNTER

I purchased this model from WISE about 5 years ago and it has proven to be a great generator. I have a 32' trailer that I keep on my property that does not have electricity available. It works flawlessly, starts every time the first or second pull and in the summer even fires up my 13,500 btu A/C unit to keep me cool which is a really good feature and is stingy with the gas. I highly recommend this to anyone wanting a great generator that will do the job year after year. (Posted on 10/16/11)
Runs like a Champ!Review by Rickola

Purchased a 2400ISHC in March 2011 to use with my travel trailer in the desert. Lucky for me I hadn't taken it there yet.
We just had a major power outage for 12 hours on 9/8/11 here in San Diego,Ca. I put oil and gas in the Yamaha, turned on the gas, pulled out the choke, switched on the ignition and she started on the first pull, and purrred like a kitten. Plugged in my TV, refrigerator and my freezer and sat back to watch the Green Bay /Saints game with a cold one in hand and a dozen more keeping cold in the frige. Couldn't be happier.
Service with Wise Sales was awesome. When I received the generator I noticed a small tab was broken on the shrouding end panel which I believe happened during assembly. Product was shipped in a box inside another box with no damage or crushing.
Called Wise Sales and they sent out a replacement part right away.

Thank You Wise Sales for such good service and great prices.
Thank You Yamaha for a great product.

never let me downReview by Ken

I bought the 2400is at 300 ft sea level and I use it at 9500ft for my rv in the mountains. I have used it for three summers and it has been dependable. It always starts and runs all day. It has never used any oil. The only draw back is it will not run my ac. My satellite and tv run with no static, a very clear picture. After my trip I change oil, clean the air filter and drain all the gas and run it dry so the carb will no clog. A very good gen. (Posted on 9/1/11)

I am an Electrical Contractor and have been using portable generators for over 30 years.
I purchased the EF2400iSHC about six months ago to use with my Travel Trailer, I am very impressed with this unit, It is amazingly quite and starts very easy. I did my research regarding the features of this unit before purchasing and was not disappointed. Shipping and delivery was was fast. I highly recommend this generator. (Posted on 8/24/11)
