Wal-Mart carries these to the best of my knowledge and they definitely have them on their website.
Here's what I did when I lost mine:
1. Buy a new one and keep the receipt
2. Take out the cord
3. Bring it back to Wal-Mart and say you opened it and it didn't have a cord (you have to bring it back in like a week or so).

If you don't want to do that, i think you can call RCA and get a replacement

Its Sucks

Go to Coby Electronics. Search for your product. If it is more than five minutes old it will not be on the list. It is on the server though. Put in the model number mp-cXX and the manuals are there in pdf form!

I work at RadioShack and have had a few customers ask about this. We don't have one specifically for the RCA mp3 players, I had a hunch that the charger for the iPod Shuffle (the newer one, not the older one) would work. As it turns out, it does. You can order one through our stores or website that's made by DLO (catalog # 55025326 ), though most electronic retailers carry some sort of charger for the Shuffle already, and you can easily find them online, too.
