The Official unofficial CPE 2000i Generator Thread

I read it on the internet somewhere:). It must be true. The 2000i Yahama spins @ 5600?
What about the CPE 2000 watt Inverter? What is it's max rpm? Anyway, for the small Inverters, I think I get the idea, it's the higher RPM to get max from the Inverter and more noise. Except I finally kinda understand why the Honda EU3000i running at 3500 max rpm might be the 'most efficient' and most quiet of the Inverters. Here's hoping we will have a winner with the new Champion Inverter.
