MP3 player overheating from to much Voltage?

I have an mp3 player, normaly run on a 1.5 volt (triple a battery), and i never use it besides in my car because we dont have to good of radio here, and it kept dying like every 2 days, so i took a charger for my cellphone that hooks into an ashtray power thingy, and i hooked + to + on my mp3 player and - to -, and well it powers it, it over heats it after 5 mins and it shuts off, it hasnt harmed the mp3 player yet, but i need to know how to limit it to 1.5 V or so, should i go out and buy a resistor or something????? idk im new to electricity!

MP3 player overheating from to much Voltage?
The voltage needs to be stepped down. Go to the store and buy a 1.5V car adapter that fits your mp3 player.
Reply:A 1.5 volt zener diode or regulator will work fine.
Reply:You're asking for trouble if you use a charger for one electrical device to charge or power another device. The exception is a battery charger that's intended to charge any battery of the specified size/rating. If your MP3 is running on batteries of a different voltage than your phone charger is designed to charge, you run the risk of damaging the charger, your MP3, or both. Buy the right charger for your MP3, and you won't have any trouble.





If your battery is having trouble holding a charge, it could be you aren't following the optimum charging procedures for the type of battery you're using. Some batteries need to be fully (or mostly) discharged before being recharged, and others prefer to be recharged before they're fully discharged. The procedure depends on the type of technology that the battery uses (Nickel Cadmium, Lithium Ion, Nickle Metal Hydride, etc.) Failure to follow the procedure for your type of battery will lead to battery "memory", where the battery remembers how low it was before you charged it, and won't discharge below that point in the future.
Reply:If you're new to electricity don't mess around with the resister idea.


Go out and buy the right adapter for the unit.


You might try Radio Shack or Circuit City.
