Most chargers for laptop computers, cameras, phones are dual voltages, so you can plug them in 110 or 220 outlets. Hong Kong/Singapore use the same outlet/plug type; Thailand uses continental Europe outlets/plugs. All of them use 220. Philippines is the only Asian country that uses North American outlets/plugs but they are on 220, not 110.

If you find that you do not have the right adapter for the outlet, just call the concierge and ask for one.
