Good advice about portable chargers. In the absence of official charging stations, there are a variety of places that you can plug a charging cord into the wall. Some that I've used and seen others using - upstairs at Columbia Harbor House in MK, upstairs at Pizza Planet at DHS, and along the back wall of booths at Sunshine Seasons in the Land at Epcot. No one ever seems to mind, so if you're having lunch at one of these places, or probably some of the other CS eateries, just see if there's an outlet near where you're sitting.
