How to straighten my hair at Splendour?

Obviously this is only a minor thing BUT if at all there's some way I can make this happen it would be super!

Ok so I'm camping at the festival campground for the three nights, only set back is that there's no power. So no use of powered stuff, this not only affects the use of my straightener but also charging my phone. I already looked up portable chargers for iphones but what I want to know is if there's ANYTHING (preferably something small and able to go on a plane) that I can buy so I can plug in my straightener?
Again it isn't to much of a big deal but I'd prefer to use it so if I could get some useful feedback I'd be stoked!

  • Which side to part your hair? (guys)? My hair is parted on the left from my own perspective while most of the guys in my school part their hair to the right in my perspective again, which way should i part my comb over? When i look at my self before i take a photo (using an iphone 5s cam), i look nice, but when a take the photo then look at it, my hair is parted to the other side, it makes me confused.
  • Where should I part my hair? I like the way my hair goes when I look in the mirror, but when I take a photo (i.e with an iPhone front camera) and its the correct way round (the way everyone else sees me) my hair looks horrible. I don't know what side I should part it on now cause if I put my part on the other side it looks stupid in the mirror, and I'm not sure what everyone else is seeing!
  • What would I look like with black hair? (pics)? I want black hair… I might just buy some manic panic, but can you please tell me what my hair would look like. Also what damage it might do. http://www.tumblr.com/blog/adrianna-rayne maybe if there's a website or iPhone app that I could use, the app doesn't need to be free.
  • Should i dye the of tips of my hair blond considering the fact that i'm 13? I don't want to look weird b/c i started to notice 8 year olds with iphones and i think it is super ridiculous b/c they are so young but then i wonder that i'm too young to dye my hair and other -older- people look at me and think that it is ridiculous that i'm only 13 and i dyed my hair.
