A new option to the parks are these Fuel Rod Charging stations.
Getting one of these means you will never run out of juice. In the park you pay ($30 at the time of this post) for a battery pack ($20 in you buy it off site – like the Orlando airport). The initial battery pack includes the fuel rod, carrying case and a USB cord with basic adapters. The adapters included a micro usb and the apple charger. If you have a different size than that then you will need to have your own adapter.
Once you buy the original pack there are no additional charges. When you want a new power rod you just walk up to the kiosk and load it in (just the fuel rod – non of the other elements); a fully charged one will come out at the bottom.
I used this on out last trip and I loved it. Always knew I had power and no need to keep charging things in the room. One thing to note is there are not fast charging to don’t wait until your phone is dead before getting one.
