Welcome to the forums!
This is a good question and one that we get quite often. Thankfully, with all of the portable electronic devices with batteries in them, there are always options for charging them.
In your case, I'd recommend heading to your local supermarket or convenience store. There are actually battery boosting devices that can give you a small power boost to temporarily power your phone until you can purchase a charging cable.
Of course, while you are there, you just might find one to fit your phone!
Thanks for asking, and hope to see you around the forums!
