Do i need an adapter to charge my iphone 5 in china?

I bought my iphone in america and am using the outlet charger normally without an adapter despite the voltage difference between the two countries. My phone is charging normally and nothing else has happened so far. Do i need any form of adapter/converter for my iphone?

You need the adapter for the shape of the outlet in China, but you don't need a converter. Electronics are dual voltage. I've charged my iPhone in China and many other countries.

You will need to purchase an adapter to fit the outlets in China.
