The kind of socket prevalent in Hong Kong is the British style socket, also commonly found is the Indian style socket.
This is what they look like:

So when using electrical appliances brought from home to Hong Kong, or devices that require recharging, such as your photo and video cameras, rechargeable batteries, hair dryers, iPhone and iPads, Nintendo DS, Sony PSP, and the like, you need to determine what kind of voltage your devices function under, if they do not run on 220-240 you will be needing an electrical converter.
If your device's electrical plug has a different shape than the ones above, you will need a travel adapter.
North American appliances however, run on 110V and so, you will need a converter so that your 110V item does not fry (literally) when you plug it into the 220V source.
You can get a converter easily and inexpensively at any electronics shop like Best Buy or at the airport shops which normally carry them. You can also check the Amazon.com selection at the bottom of this page. But before you rush to get a converter also consider the following:
How to tell if you have a dual-voltage appliance? Look in the back of the charger or item where the power input/output is described.
Look for the "Input" specification which should read something like this:
That tells you the voltage the device will take. If it says 110V but there is no mention of 220V or 240V, your device only works at the lower voltage and you will need an electricity converter in Hong Kong.
Now that you determined whether you have the right voltage to use your devices in Hong Kong, in order to plug them into the Hong Kong electrical outlets (sockets) chances are you will need an electric adapter, unless you are travelling from the U.K. where sockets are compatible with the Hong Kong socket.
A travel adapter is simply a connector that matches the shape of your plug with the HK wall socket. An adapter does not change the voltage of the device, the converter does that.
Some of the newer Western hotel chains do provide adapters in the rooms for the different styles of plugs in America and Europe, but do not expect that to be the case at smaller hotels and guest houses.
In any case, I would definitely bring a couple of Travel Adapters with me just in case, they are inexpensive and that will keep from having everyone in the family fighting for the one outlet in the room to charge their devices!
When buying an Electric Adapter for Hong Kong pay attention that you are getting what you need, some "Universal" sets might include only US to Europe so it is best to double check. Some sets also include the converter, some only the adapters, so yes, triple check again and make sure you get what you need.
So in this case, you will also need a different adapter for China. See more about Electricity in China here.
Adapters for this kind of outlet are also included in the Travel Adapter Sets.
Some of the adapters and sets also include a USB charger, which is what you will need for charging certain devices like iPods, iPhones, iPads etc., you can also get the Apple Travel Kit, see below.
