Ok, is the cable physically connected to the charger or does it plug in? If it plugs in, just replace the cable. Do you know if the Samsung power connector is a micro or mini USB connector? Or something unique to that model (I am guessing USB, but not sure.)
If the cable is hard wired and can't be replaced but the unit uses either micro or mini usb, then any such charger that has the same type of cable will work. You may want to check the output of your current charger (it's usually on the charger in small print) and use something about as powerful, but the chargers generally are interchangeable.
