I was going to order an Astroflight 109, but read that you cannot feed it from an automotive battery. A special wall power unit is supposed to be needed. Is that right?
If so, the Astro 109 appears pretty useless at the field if no AC main power is available.
Is the info about the necessity of a special power unit correct?

Where did you read that? It's BS.
An automotive battery is the CLEANEST, MOST STABLE source of 12VDC power available. There is absolutely positively no reason why the Astro 109 cannot be powered by an automotive battery.
There might be an issue in a RUNNING car, due to the extra-high, unstable voltage put out by the alternator, but again, a regular automotive battery is perfectly suitable!
