Would it harm an electronic equipment if we use AC current when it asks for DC current?

Question

Actually its my MP3 player. It says that we must have a 3.5V DC current source.
However, as I had not noticed it erlier n all, I used AC current. It worked absolutely fine.
Now I wanna knw if this is harming the player in any way.
PLz. help!!!

Answer 1

of cause it going to burn out ur electronic equipment ,
when u use the DC current ONLY with AC current, but u mention that ur equipment is working so fine that is IMPOSSIBLE.
unless u use the AC power adapter to DC .

but even u use the DC adapter, if ur equipment is require 3.5v of DC and u use them with 12v instead it will burn out the equipment in less than 10 min too.

by the way i just wanna let u know it very dangerose to use any self made AC or DC power connection.

keep out !!!

Answer 2

I find it hard to believe that you plugged 110 volt AC into a 3.5V dc MP3 with out it cooking but if it worked - well then it worked.
