Cellphone charger: don't leave home without it

I can't find my cellphone charger and my phone battery is almost dead. This is not a good thing when you are searching for a job. I turn my phone on every half-hour to an hour to see if anyone has called then turn it off. I've heard of people using reiki to recharge their phones, I'll be giving it a shot later tonight. I'll need it because my mom will probably be calling me. I think have to break down and buy a new one if I can, my phone is over a year old and therefore is ancient technology.
