For example a European plug will typically be a Type C, whereas a US plug type will be a Type A. However in Asia you can find that there is a mix of plug types being used. North AmericaThe voltage of North America is 120 volts, with most electrical goods operating at around 110 volts. The plug type is two prongs with a third optional round pin.

Types of Travel AdaptersSingle Regional Adapters – These adapters offer a single adaptation from your electronic device, to you destinations electric output. So for example this could be a UK three prong plug to a European 2 Pin plug.Multi Regional Adapters – These adapters offer multiple plug type options with multiple output options for travelling to different regions. So for example an adapter could have up to three types of plugs as the source and then have up to three types of plugs for the outlet. Grounded vs. Non-Grounded AdaptersA grounded adapter means it is suitable for use with a three-prong type of electrical sockets. All devices will work normally without the ground wire because it’s not a part of conducting path, however, grounding guarantees an extra security and protection for your appliances. Non-grounded adapters mean it can be used with both two and three prong type sockets but do not secure device from electrical surges.
