My iPhone charger doesn't work. Any alternative I could use before I buy another one?

I need help As soon as possible! I need my phone tomorrow, and its dead. I've tried everything I can do! I've tried taking lint and dust out of my phone and charger, I've plugged it into other phones, I've plugged it into other outlets and bricks, as well. I plugged the charger into a light up brick, and even without the phone, the light of the brick went out, which is NOT supposed to happen, by the way. This is urgent!
