Wireless charger for my Iphone 4S?

I live in Nepal and we have power cut all the time. Like 10-12 hours a day and I barely get to charge my phone during those times. I play candy crush a lot & my battery runs out quickly. I have heard about wireless chargers which can be used during these times but i don't know where to buy them. Any idea?

What could I do with 750MB and or 1GB?

I want to get an iPhone 5 for Christmas but I don't know which contract to get?
I use my phone a lot everyday and would use it a lot if I had an iPhone, for twitter, Facebook, instagram, tumblr and most other apps too. I don't which contract to get either the 750 MB or 1 GB because I'm scared I would go over the amount so which one is best and what could I do with both?!
(both contracts have unlimited texts, just the amount of data and the minutes change)
Thank-you
