Yeah, I agree. Besides, the 3300 has a fixed LiIon battery, which kinda negates the "always and everywhere emergency power" paradigm.

I haven't been able to find the 1550 in a European shop yet, but I can confirm that a (rather cheaply looking) 4AA charger for the Archos PMA430 I had lying around does indeed work with the Itablet -- with a Nokia tip adapter, that is.

I don't know if it has a voltage regulator -- heck, I don't even know if it has a counterflow diode! -- but it works and gives similar results as itsbill's test.

I'm not too worried about voltage regulators anyway; I've hooked my Itablets up to some crazy sh*t in the past and they're still not charred. The onboard regulator circuits seem to be working just fine...
