Champion's generator with the 389cc/13hp engine is advertised at 6500/7800 watts with no posted amperage output.

Does anyone know if the champion amps are posted anywhere? The manual says there is a 25amp breaker on the 30amp RV outlet, but I need something more concrete than that.
I can't comment on Onan's service, since my Homesite 6500 has been problem free.

you can divide the wattage by the voltage to get the amperage. Thus, 3,500 watts / 120 VAC = 29 amps.

But, as you noted, the circuit breaker for the RV outlet is 25 amps and the breaker for the duplex outlet is 20 amps. Those will be your limiting factors. The generator will provide the full amperage of the breakers.

I understand the formula for deriving amperage from wattage and voltage-basic physics learned in high school. What I don't understand is why the amperage is not specifically stated, as other manufacturers do. 3500 watts from that size engine doesn't seem plausible. If indeed 3500 watts are being produced, what is being sacrificed to attain it? It is noted in previous posts, that many believe the Champion 3500 is only capable of producing 2600 watts, which would translate to 21.5 amps. Before I buy, I would like to know for sure what amperage the unit is actually producing. As I stated in a previous post on a different subject, factual data is important to me.
