This was the Year of the Portable Charger. We’d never seen them at expos before and suddenly, they were everywhere and makes sense. While wifi may be available, who’s going to have the time to stop and charge the phone or tablet?
Note to self: if you’ve scored some with adapters that aren’t compatible with you phone/device, charge it with the cord it came with, and make sure to carry your own when you’re out and about: they’re USB. Is it rocket science?
Our phones do come with them, but we do see them everywhere, and in all sorts of packaging and colors. Always good to have a spare pair or five.
