i'm traveling to Thailand/Hong Kong for 2 weeks. I only have 2 batteries, so I probably won't have enough to last for 2 weeks. I was wondering if these countries use the same electrical outlet as US so that I can use the battery charger? Or will I need to get an adapter? If so, what/where can I get these adapter?
another option is to just buy 2 more steringtek batteries?
thanks!!
