Question about Generators and boon docking

The more I thought about this the more I thought I should ask.

Just returned from our first boon docking trip on a generator. I know the led lights, bathroom fan, radio, etc. are all 12V and draw from the battery. When you have a generator on do they draw from the generator power, or from the inverter (I think that's the term) which is powered by the generator? If you have a lot of led's and the radio on - would that cause any kind of significant draw on the generator?

thanks

"...from the inverter (I think that's the term)..."

IMO, the first thing to do is learn the terminology!
INVERTER: Converts DC voltage (usually 12VDC to AC voltage (usually 110VAC).
CONVERTER: Converts AC voltage (usually 110VAC) to DC voltage (usually 12 VDC).

While they apparently make inverter/chargers, I have never seen one, so I have no idea how it works.

Every RV I have ever owned had a converter/charger in it. When hooked to shore power or a generator, the converter/charger supplies DC power to the RV, and charges the RV batteries (but it normally does not charge the chassis batteries in a Class A, B, or C.

I have never owned an TV that came from the factory with an inverter in it. I know they are built, I simply have never owned one.
