The A7 can work with standard AA batteries so you could just pack several extra sets.
Without knowing what country you're in and what country you're traveling to, I can't give you any specific recommendations, but a local electronics or office-supply store should have a selection of adapters to fit the plug of your charger into foreign power outlets. I found one at a nearby Radio Shack for my upcoming overseas trip.
