Buy a Mophie perhaps? This is what I use for my iPhone when flying with iGlide.

I picked up an 8600mah PowerBurst from Costco for $30. It will fully charge my iPhone5 3 times and after flying for 5 hours the phone is still at 100%. It has to be connected by cord to the phone but that has been workable so far.
