I need a few hours of AC power (< 4 amps peak) tonight at a remote location
(astrononomical telescope mount, laptop). Is it safe (in terms of possible
damage to the car) to use my '06 for this purpose with a suitable inverter?
That would mean having the car turned on for about three hours.

IIRC, the limit of power is about 120W at the plug. At 12V, that's 10A.
Given the low capacity of the 12V battery (~30Ah), it means that you
will need to be in "road" mode to not exaust that battery very quickly.
Which mean the engine will run often and randomly. It might impact your
astronomical observation: vibration and source of heat.

Thanks. I can manage the observing part. It's the car being on for hours in
Park that I was concerned about. BTW, on a typical natural surface, having
a motor vehicle idling nearby does not produce vibrations that are
discernible to visual observers. As for heat, one does not typically set up
near the car's exhaust pipe. And it's going to be 33 C tonight, anyway.

I've been in some horrible traffic jams where there was little to no
movement for a couple of hours (I think more than three hrs on a couple of
occasions) and the air conditioner was on all the time and so were the
headlights. The car survived just fine. In fact, I think Prius is pretty
much designed to work in just such condition, common in metro commute. It
seems very similar to what you're talking about except you will have it
on \"park\" all the time whereas in a traffic jam you have it on \"drive\"
most (or all) of the time.
In your case it may be easier on the car and the ICE may not even have to
cycle as often if you turn everything you don't need (lights, A/C, radio)
off. I don't think it's going to be a problem to leave it turned on for
a few hours like this.

Indeed. Piece of cake. I drew power from 8 pm to midnight and ran two
telescope mounts and two MacBook Pros and it worked like a charm. It was
funny to have people ask "How/why is that car starting its engine without
anyone in it?" "Which car is that?" "That car." "Oh, THAT car. Yeah, that's
my car. It does that sometimes."
