Thanks for any feedback. I consider this s tough question and would have to look to Yamaha owners for feedback. The CPE 2000i uses a minimal displacement engine, the bare minimum to meet its electrical power specs. The Yamaha 2400 on the other hand is "over-engined", having a larger displacement engine than needed for its ratings. It's the same displacement, 171 cc, that Yamaha uses in the 3000 watt inverter generator, making the ef2400is displacement greater than both of the Champions put together. So maybe, big emphasis on the maybe, the Yamaha won't be degraded by the altitude as much as the Champions. IMO the only way to know for sure is to test both setups at the actual altitude. Congrats on reading the entire thread. I vote for some kind of attention span award! For what its worth, here in Edmonton Alberta (elevation 2192 feet at 79 Fahrenheit), the ef2400is was not able to start my ac, but twin 2000i were no problem. I do not have a hard start, that might make it easier? I didn't read the amp draw or anything, this was a real life test with my friends ef2400is and my twin 2000i. Rob.Re: The Official unofficial CPE 2000i Generator ThreadAgree, I wasnt meaning it for a solution over a hard start kit, more of if you use a hard start kit and the generator still cant handle it. But I just did a bit of looking and the UPS I tested with was 2200 VA and depending on brand they can be cheaper or can be way more then this generator. Just my 2 cents as another option. I am getting a SPP6E, I just havent ordered it yet.Re: The Official unofficial CPE 2000i Generator ThreadHey Guys first off I would just like to thank everyone on here that spoke so highly of this generator. I bought it based on the good feedback on here, I love this generator. After having a fewer knock-offs I am amazed not only by the quality of this unit but also how super quiet it is. I am not kidding, specs are specs and either most other brands lie as they are suppose to be similar but man this thing is amazingly quiet. I have a 23.5 foot trailer with AC and no hard start kit. The generator almost started it. My previous generators wouldn't even come close. This little guy tried hard to start it almost to the point of stalling before the overload clipped. So having been in computers my whole life I wondered how I could stop the dip of voltage and amps to help start the AC so I took out an old UPS I had sitting around and wouldn't you believe the AC started right up and the generator didn't really notice it. (eco off) It also kept it running with eco on. So I wonder why wouldn't people having a hard time starting things look at getting a UPS? I know having to carry around another appliance and they are not light but you would have to do the same if you bought 2 generators? Last I checked you can get a fairly big UPS for a decent price, cheaper at least then a generator. Thanks again everyone!
