    The Honda EU2000i doesn't even provide 12VDC. Yes, there is a 12V outlet, but it's hardly DC. It's from an AC winding, and only passed through a bridge rectifier. No filter or regulator at all! The manual says it is only for charging batteries. I suspect it would stand a good chance of destroying a radio if you connected the radio directly to that unregulated output, and I'm sure it would produce lots of noise.

    The Honda is an excellent source of portable 120VAC at high power, but a lousy source of weak, unregulated, unfiltered, noisy 12V at low power. The approach of using the 120VAC output to feed a power supply that produces 13.8VDC may smell of Rube Goldberg, but it is the most effective way of getting clean 13.8VDC from the generator.

    One good thing to do is see if you can get a maintenance manual and parts.

    Because you will need them sooner or later.

    Just taking one apart can be a challenge.

    I purchased a Champion inverter generator a couples years ago. It created a 20db+s9 noise floor on 40m. I could move the noise floor to 80m by adding extension cables. Back to the store it went.

    Good to know... and sounds about right.

    My 4x Group 27 battery w/ homebrew 30A linear float charger is DEAD quiet, and never runs out of gasoline:

    The first set of used batteries lasted a dozen years. :)
