Using DC Instead of Batteries |Please Read|

Dec 15, 2005 8 Replies

Hey, I really hope you read this, because I've really been wondering.



Is it possible for me to use my Input (120V 60Hz 11W) to Output (DC 6V



300mA) for my Aiwa CD player on my TDK MoJo MP3 player? This normally uses one AAA Battery. But I'm usually in short supply of batteries, and I want to use this MP3 player at home. Isn't there a way I could connect the wires together or something like that...?

Thanks a million!

This is definitely a good post for sci.electronics.basics.

A 6V DC adapter would almost certainly do bad things to an MP3 player designed for one AAA battery. You need something that puts out about 1.5V.

Well, lets say I could get one of these from Radioshack. From then on, what would I have to do?

Thanks again

Attach the + wire to the terminal where the button on the battery goes, and the - wire to the terminal where the flat part of the battery goes. This will require ingenuity, or alligator clips (which you can also get at Rat Shack).

If you wanted to get fancy you could make something that was the size of an AAA battery but had a wire coming out for the AC adapter. Probably not worth the time, though.

Hmm, this is more complicated than that, I think. See, the adapter has a jack on it, a jack that would have normally gone into my CD player's input. How would I connect the wires as if they were batteries?

Thanks

Tim was suggesting what most of us do in this case. Use scissors (wire-cutters if you want to be fancy) and cut the jack. Then strip a bit of plastic off the wires and connect the exposed wires to the + and

- terminals. You may need a multimeter to find out which wire is + and which is -.

Doesn't the player have some kind of printing, or embossed little figures, next to the jack to tell you what its power requirements are?

Thanks, Rich

No, putting 6v (or IRL probably 8v) into your 1.5v player will kill it. You would need to put a 1.5v voltage regulator between the 2, or else buy a wallwart that give you 1.5v. Do not conect your 6v one to the player directly.

Alright, tomorrow I'ma go to Radioshack and get a 1.5v if they have one.

Thanks to Everyone
