So how can I tell if mine supports use on the wall-wart? Any risk if it doesn't?
And how beefy a 12 volt supply does it take to operate it that way?
I thought I just said, but obviously wasn't clear enough. Sorry about that, let's try again. Turn yours on, then plug in the charger. If it still runs it won't work with PA. Alternatively, plug in the charger and while it's charging try to turn it on. Again if it will 'use while charging' you're SOL.
The 'PA able' one will charge or run but not at the same time.
It will not run PA on 12 Volts, that's what nine Volts is for? PA on 9, charge on 12 automatically. The PA needs to be at least 2.25 Amps (marginal, 2.5 or more recommended)......but at 9 Volts not 12?
No damage from undervoltage. Random useless flashing up to about 7 Volts, then PA mode to 9 (no charging), then more nonsense up to 10.2 or so when proper charging starts and works up to 15 Volts. In no case apply more than 15 Volts, 13 is a much safer upper limit.
If your unit is one of the newer versions (with larger air holes and less restricted draw) you're SOL. 'Use while charging came before that. The last new ones to ship that way (allow PA) were several years ago.
