I just went to target around the block from me and bought a "just wireless" for all samsung phones for $15. they had four different connectors for samsung phones. In the store, I found the match. I plug it in at home, the charger green light comes on, but the phone doesn't come on to indicate "battery charging" It's made in China. My samsung phone is a SGH A 517. I'm going to return this. The OEM charger is almost $30 from At&T store, I'll keep looking.
