"Just charge in town."
This appears to be the answer to most everyone's electronics not using AA or AAA batteries. But what does everyone exactly mean by this? Where in towns? Are you asking private businesses (e.g. gas stations, Mom n Pop stores, restaurants) to use their electrical outlets or are you utilizing public facilities like public bathrooms or a public library?
I'm trying to decide whether to take electronics that run on AA and AAA batteries, or to rely on businesses' goodwill to charge up my electronics.
