I want to take iPhone4s when I travel to Xinmatai. Is the plug for hotel charging suitable for Hong Kong version?

The Hong Kong version can be used in Singapore, but not in Malaysia. You need to buy a converter. The power outlets in Malaysia are as follows (I took them with me when I traveled):

In Thailand, it is generally a two-hole socket, just like in China. You can bring a two-hole plug. If you want to insert three holes, you need a converter. 7- 1 1 All stores in Thailand sell converters, so it is cheaper to buy them in China and take them with you.

There is usually a converter at the front desk of a hotel. Don't worry, but you'd better bring your own converter. Hotel converters are in short supply.

I hope it helps you, and have a nice trip ~ ~
