Probably more than 1.2 V. More below.

If the "charge" indicator on the MP3 player comes on and stays on, then you need a 1.5 V adapter.

A thrift store can be a good place to find an adapter, if you don't mind shopping around a little.

You probably don't need arc flash protection at this power level,...

I've seen some arc flash videos, and they are quite dramatic. I think I can avoid that fate by being careful.

I have several shoe boxes full of wall warts. It was a thrift store that came up with the computer cable with the odd Rio plug on one end. There are two thrift stores nearby with bins full of cheap, as in $1 or $2, wall warts.. At yard sales, they usually fetch less than that. Finding one with the right current and the right voltage and the right polarity and the right size connector is the trick.

I've been thinking that 3 volts was about right.

Thanks for the help.
