The manual says that the connection in question is a 12V 8.3A power

_output_. As stupid as it seems it then goes on to tell us that it "is not

intended for use to charge automotive batteries."

It's not as stupid as it might sound. To charge an auto battery, you need
more than 12V. If all you have is really 12V, the battery will be about 25%
charged.




The cable for this

connector is supposed to be included with the generator, or so the packing

list says, and it has conductors with alligator clips on the end so the "no

batteries" stuff seems to make even less sense since alligator clips aren't

exactly conducive to other uses.

I agree, that would seem to suggest that battery charging was in mind.
In which case, maybe it really puts out the higher voltage required to
charge the batteries, not 12V.

This is true. A DC meter should read average voltage. Being a
rectified sine wave, average voltage would be 0.636 times the peak.
Peak would be 1.57 times average, or about 18.8 Volts if the average
reading is 12.0.
