1.Guide Review - International Electrical Adapter
Why do you need an electrical adapter? An adapter allows a dual voltage appliance, converter, or transformer to be plugged into a wall outlet that is different from the pin configuration on the appliance, converter, or transformer. It gets more complicated. Different countries require different adapters. Rather than puzzle out which adapter you'll need, just buy this one -- it has four adapters folded neatly into one unit and it's worked for me while I flashpacked across the UK, Europe, Australia... I don't travel without it.

It could hardly be easier. Instructions show you which of the four plugs to pop out for different countries and, after you lose the instructions, you'll find parts of the world printed on the plug adaptor itself for:
1. Europe, Middle East, Asia and parts of the Caribbean, Africa and South America
2. Australia, Fiji, New Zealand, China and parts of Japan
3. Other parts of South America, the Caribbean and Japan
4. Great Britain, Ireland, other parts of Africa, Hong Kong and Singapore
