Differing voltages and standards can often be daunting when planning on visiting another country especially if you've never visited before. These instructions have been written to prevent you having to worry if you'll be able to charge your iPhone 3G when you're in America.The following step-by-step guide shows you what you'll need to charge the iPhone 3G when staying in America by using the B or A type 120 volt 60Hz plug outlets, most Americans use Type B wall outlets. Most power sockets differ regionally so we recommend that you read the WikiConnections global power supplies page where you'll find a complete list of regions and countries. If your iPhone 3G slowly recharges or doesn't turn on when you are visiting America from a different country please check that it is compatible with a 120 volt power supply. Typically devices which originated from a country which use a higher voltage (for example 220 volts) sometimes take longer to charge or won't turn on, check that the iPhone 3G is dual voltage (you'll find these are usually indicated by 100-240 volts) else you may need to use an additional converter to ensure proper use. These instructions assume that you are running Apple iOS 4 or greater on the iPhone 3G.
