TE Power Supply Really Matter?

[dpaint4]

Why can't I use any  adapter of equal voltage with the right conector?  Does it really matter like the manual says?  I'd like some input on this before I put my unit at risk.   I'm just thinking, how could the unit tell if the power it's getting is the same?  Thoughts anyone?

check out the tg16/duo FAQ (at gamefaqs, among other places)...it has a discussion on AC adapters and what to do.
