EDIT ADDED 45/5/2013- When this thread started in March of 2005, I never expected to see it survive this long or amass the quantity of information that has been shared here.
In the eight year run of this thread we have amassed almost 10,000 postings and surpassed a million views. This creates somewhat of a dilemma for anyone who has just discovered the forum.
Since the amount of information is virtually overwhelming, I suggest you set your preferences for this thread to read "newest first" and then begin to page backwards.
What you will find in these pages is a wealth of info on virtually any make or model of Chinese manufactured synchronous (non-inverter) generator in the 3,000 watt performance class. Info will include how to rewire series coils to parallel to obtain maximum wattage from a single 120 volt outlet. Tips on further reducing sound levels, how to care for these generators, which ones are "RV ready" and provide the best overall performance for the dollar invested. Which companies NOT to deal with, where the best prices are, how to safely wire the generator into a home or RV, how to check your RV for electrical faults, sources for generator accessories, which 20/30 adapters are safe to use and which are not. How to convert a gasoline generator to propane or NG. This is only the beginning. The forum has a life of its own with the focus sub-topic switching frequently. Still, the main topic of utilizing the amazing, inexpensive Chinese gensets is always there. The amount of creativity and innovation presented in these pages is indicative of the talents shared in the diverse backgrounds of the folks who make up our combined RV community.
Many of the original brands and models of Chinese gensets mentioned in the introduction and early pages of the thread have since disappeared. New EPA and CARB emissions requirements, company bonds assuring the emissions warranty will be honored even if the company goes out of business, and fierce competition in the industry have changed the playing field. Champion Power Equipment has become the apparent "trophy team" providing an ever expanding retail outlet, an ample parts supply, a strong warranty and excellent customer service. CPE has continued to improve their product and now offers a new model (#46538) with exclusive convenience, safety and performance features aimed at the RV market. Big names like Cummins/Onan, Honda and Generac all now have Chinese built open frame synchronous gensets available. Ironically, the prices often found on these gensets has not significantly changed during the past eight years - even with the devaluation of the American Dollar and new EPA/CARB requirements.
I also encourage you to use the search function and even the advanced search options to find information. Key works such as "rewiring", "PowerPro", "Champion", "Onan Homesite", "Duropower", "ETQ", "Jiung Dong or JD", "Tractor Supply", "Costco", "Lowe's" and "Home Depot" are all examples of keywords that will give you specific information on different models being sold by retailers today.
Or, you can fill your glass with your favorite beverage (keep more close by - maybe some munchies as well :D, sit back at your computer, tell your wife (or significant other) that you will see her in the morning and spend the next 10 or so hours reading through the postings.
No one on the forum gets mad if you ask a question that is a repeat. Please do not hesitate to post to the forum. All questions are considered important and those active on the forum will do their best to respond with a valid answer.
Also note we are not out to knock the Honda, Yamaha, Kipor or other brands of high end digital gensets. We recognize the quality of these products and their suitability for quite, efficient RV use. But, there is a flood of reliable, inexpensive and comparatively lower cost gensets coming out of China that are excellent alternative choices for the RVer wanting power to run an air conditioner, microwave, etc. without excessive noise or breaking the budget.
Oh, one last thing. The folks on this forum are true gentlemen. We do not flame one another or the product discussed - period. Ugly contributors usually have their comments and remarks ignored by our masses. It is not a forum to start arguments to obtain a clear win. We do disagree on many issues, but we have all agreed to do that in a respectable manner.
We now have the introduction of more and more inverter gensets. There is a rather extensive thread named "The Official Unofficial Champion 2000i Generator" on this forum. Today, I added info on the new Champion 3100i inverter genset. Discussion on this product may get moved to its own thread at a later date.
Many have looked upon this thread with distain saying Chinese is cheap and doomed to failure. I remember saying exactly the same thing about Japanese products a few decades back. But, over the past eight years the track record for Chinese built generators has shown otherwise.
Please, join us in a fascinating journey down the Chinese built genset road of knowledge.
This is the question I posted that got it all started back in March 2005.......

For a little over a month now, I have been somewhat intrigued by the availability of a 3000 watt, 6.5 HP generator at Pep Boys and Northern Tool for under $300.00. The engine on this generator looks identical to a Honda 6.5 HP OHV engine. Knowing that the Chinese have become very adept at โcloningโ reputable technologies from other manufacturers, I was not surprised at the similarities. Neither store could give me any information on the generator nor did they have a โrunningโ display model.
I have done a little research. This is what I have discovered:
Many of these generators are imported by ELIM International (www.eliminternational.com) out of Buffalo, New York from Jiung Manufacturing in China. (The unit at Northern is identical but carries the JIUNG name.)
The engines are indeed a Chinese knockoff of the popular 6.5 HP 196cc Honda Engine. โSupposedlyโ Honda has licensed the engine technology to the Chinese manufacturer of the product.
The Chinese company that makes the ELM3000 generators is a rather large, diverse, long-standing company with a reputation for โabove average qualityโ Chinese made products (Jiung Manufacturing). There are many more Chinese companies making almost identical gensets.
The generators at PepBoys do have a six month limited warranty. But, it is only on the engine (not the generator) and requires paying for shipping to and from Buffalo. Probably not a very practical thing to do if you have warranty issues.
ELIM does supply replacement parts (a PDF parts manual is available on the ELIM web site). No prices are given for replacement parts nor is there an โavailability listingโ.
The generator head itself is a brushless design. The only really significant wear parts in the generator are the bearings โ most likely universally available.
The published dB rating is 67 at 23 feet. This is โreasonablyโ quite for a generator of this size as most comparabl.... The 67 dB rating is the same as Honda gives their 3000 watt CycloInverter with a โlook alikeโ eng...

While what you say is true, there is one other issue that should be considered. Lowering the sound level by 3 db reduces the sound (air) pressure enough that the distance at which the sound can be heard is significantly reduced.
A 65 vs. 68 db noise may sound the same when standing next to the noise source, but move back 35 or so feet and the 3 db loss really makes a difference.

Anyone try running the exhaust into a bucket of water in an attempt to change the pitch of the exhaust tone? I would imagine if the end wasn't too deep , the backpressure may not create a performance concern....
Or is the higher db due to engine noise?

Wow....what a long and interesting post. Since I didnt feel like reading through all 3500 plus postings here, maybe someone can give me a relative answer. Im looking for a smaller quieter generator...mainly for battery charging. Here's where the "relative" part comes in. My on board 10KW diesel is fairly loud although I dont have a DB meter to test with but I want something that I can run, lets say in a State/National Park, without distrubing the neighbors while maintaining my batteries. I see the Champion 4000 watt is rated at 68 DB and their 1500 watt at 65 DB....the Honda's are what, in the 58-59 DB area? Did I read here before, that 3 DB is the level in which you can audably hear a difference? OK...forget the facts and figures....would one of these be less distrubing than my Diesel? (older 1996 Power Tech 10KW Diesel). Tough question I know...but any thoughts would be appreciated..

Are these models unique to having the cast iron cylinder sleeve? Or do all the Champions have this? Anyone know?

Maybe someone can figure out the puzzle to find a Champion 3500 120v with that 120/240v twist lock. Just try going the the NEW Ultra-Fab web site (www.ultra-fab.com) and see if you can find a dealer and if you find a dealer does he have one in stock. I understand completely what you say about the "NEW Blue Ultra-Gen Powerhouse Generators" not coming to market maybe until Mid April but they show all those fine looking YELLOW & BLACK Champions for sale. And is there no longer a 40008. Only found maybe two other posts other then you and MrWizard who posted owning that unit, if I am correct. Maybe MrWizard can give us the name of his dealer. PPL in Houston no longer lists the Champion 40008. Maybe someone can give us a online dealer.
Once again, the twist lock is rated for 120/240 volts. Just because it has a 240 volt rating does not mean it will supply 240 volts.
