    Post DC adapter for portable player

    I have a dc car power adapter that came with a CD player. It supplies 4.5V. I have a DVD Player that needs 9V input to run.. is there any way to modify the dc adapter to power my portable dvd player from the car?

    Thanks

    most likely not without unsoldering things, however you can prolly easily buy another one from your local neighbourhood radioshack for $22 that's a universal adapter. OR you could get this one for $9 if you don't need more than 500mA.

    I don't think it's worth trying to hack something apart if $9 will get you a new one.

    good point
    will any 9v car adapter work with it do you think?

    because the reason i was wondering was that i saw one for another player for like 40 something.. i thought it might be proprietary or something

    It needs enough amps...look at the AC power adapter, or on the bottom of the player, it should say the volts and amps.

    The only proprietary part may be the plug, but if radio shack has it, that rules out that problem.

    IF they don't have it, you could always cut the one off the AC adapter.

    Take a look at the Car CD Player adapater at http://www.aaroncake.net/circuits . Should be what you need.

    went to radio shack today and bought a universal adapter.. i hooked it up with 9v to the player, and it works fine..

    EXCEPT THAT

    now i can barely hear the audio through the casette adapter, its very fuzzy and i have to turn it up way loud

    when i run the player off of its battery, the audio through the casette adapter sounds very nice

    any idea how/why this is happening and how i can fix it?

    thanks

    Cool

    Sounds almost like your universal adapter cannot supply the current necessary to run the player properly.

    This happens sometime when using my car kit and my discman in the car i think the cigerator plug and the tape thing interfere somehow or sometimes its better to put cig thing in first then tape.

    i think it might just be a cheap factory head unit thats causing this but i think if u play around with it space thigns out u should beable to get it to work.
