Question

My home charger will not charge my cell phone, my friend told me this can be because of a shortage in the wires? I will not be able to go to town until Sunday, is there any other way that I can charge my razor phone? I don't have a house phone, so this is the only way for me to keep in contact with family, by the way, my sister is in the hospital, so this would mean a lot to me if someone could help me out! Please!
