Touchdown! Greaser!
There are electrical outlets at the Green and Red shower buildings in the North 40. I recommend you bring your own power strip for extra outlets. At any given time there will be thousands of dollars worth of iPads and other devices charging and left unattended and nothing in my 4 years of experience has ever happened to anyone's stuff.
What I did last year was I got a set of portable solar panels that can charge USB devices. Working in conjunction with a USB battery pack I was able to keep my phone charged up the entire time.
This is the solar panel I got: http://www.amazon.com/Anker®-Dual-Port-Charger-PowerIQ-Technology/dp/B00E3OL5U8
Great idea!
