Sometimes you can find Universal car chargers that will work for your phone. I think they also have some portable cell phone chargers that run on batteries that you can find at like Walgreens or other stores. Otherwise see if you can find a cheap Samsung replacement charger I'm sure you don't really want to pay full price. Good luck!
if you have the data cable for it, that hooks into your computers usb port, hook it up there, that will charge it also.
