But again, I am not asking about the CIGARETTE LIGHTER PLUG. I am asking
about
the ACCESSORY port in the car, which is supposed to be used to power
"accessories", like inverters, computers, etc.

Andy-

I had assumed that the accessory port used the common lighter sockets as power
connectors. If that is not true, perhaps they use a connector that would be
better for general high current use. Please elaborate.

If it does use lighter sockets, that was the basis for my suggestion to use
something different where more than 4 or 5 amps of current is involved. Yes,
that would result in "hamifying" your vehicle, but it would provide the
capability for higher current equipment.

You mention inverters being used with the accessory port. A common inverter
would be one like Radio Shack's 300 watt unit. Fully loaded, it might draw
about 25 Amps. Although your accessory port may be rated for more than 25 Amps
total, I don't think it is a good idea to draw that much out of any one lighter
socket connector.
