The flat out noise level is unknown to me. But for $270 the old fashion Champion C46540 gave me pure pleasure today when I started the beautiful little power house in my gen house. Previously, it was used for a short time to power a MH with a 13,500 A/C and all electric fridge. Are these Inverters going to prove to be good only for light duty service? What can be powered with 400w to keep them at a low noise level? And is Honda & Yamaha alone in the 2000w class? I hear the Honda 3000i is quiet with high output. Is this true? What dbA level?
