Just got back from a week at Buddy Dive and will post a trip report soon. As far as the power went, I used a travel surge protector and a Bestek converter I got on Amazon to convert all incoming power to 110v US. Probably didn't need the converter, but was happy to see it work. Fan noise (a common complaint on this particular converter) wasn't a problem as the converter was in another room during the night while the batteries were recharging. Other folks said they just used their chargers in the wall and they worked fine for recharging batteries, phones, iPads, etc.
