Perhaps it's a silly question with an obvious answer but I felt I needed to ask before I do something i'm uncertain of. I don't want to buy GoPro's own expensive battery chargers (as of now at least).

Higher amps doesn't matter.
Your 5.3V Samsung charger as well as the other 5V USB power supply are both fine.
Many USB hubs have 5.3V output, as well as most powerbanks.
