I am taking my iPhone5 to Peru, where the voltage in electrical outlets is 220V. Can I recharge my iphone directly from the power outlet without using a voltage converter?

Yes, if you take your iPhone charger with you. You may need a wall outlet plug adaptor such as those in Apple's World Travel Kit.

I would like to have a go at this.

I am presently in Hong Kong. Just prior to this trip, I purchased an iP5. I have taken my iP4S to many countries and charged the phone by either using the USB connection to my laptop or by using Apple's World Travel Adaptor Kit.

Only after getting to HKG did I try to hook up my iP5 to the Apple travel adaptors and of course they do not fot and I do not have an adaptor that goes from 30 pin to the lightning cable.

So is it actually safe to take the original iP5 cable and charger and simply add an international plug adaptor that I am also using with my laptop? If so does that in fact mean that the iP5 can take 220 without converting the voltage that I thought was done by the Apple Travel Adaptor Kit?

I should amend my note to say that I could not get Apple's lightning cable to fit with their own Travel adaptor but I have a lightning cable by AT&T that does work although it is very tight.

But I am still curious if Apple travel adaptor regulates voltage or if my iP5 from the USA is actually universal voltage.
