An Apple iPhone is a handy device to have around when you travel overseas. However, when the time comes to charge the battery, you may find that overseas power outlet's voltage capacities are not the same as they are in the United Kingdom. Fortunately, there is an easy and inexpensive solution for charging mobile phones in other countries. With an iPhone, it is even possible to charge it without the need for any extra adaptors or cords.
Plug the iPod's USB cord into the iPod power adaptor. Plug the other end of the USB cord into the iPhone.
Plug the power adaptor into an international power adaptor. International power adaptors generally come with multiple plug options, so you can use it no matter what country you are in. See ElectricalOutlet.org (link below in Resources) for a country-by-country list of standard voltage. Check the instruction manual if you are unsure about how to use your particular adaptor.
Plug the international adaptor into the wall. The iPhone will charge as it normally would at home.
The iPhone can also be plugged in directly to a computer via the USB cord. International power adaptors can be found at most electronics store.
