Other Do travel adapters hurt/hinder iPhone/MacBook chargers?

[SW3029]

Maybe this is a stupid question, but if I am using an Apple charger to charge my iPhone and an Apple charger to charge my MacBook – if I go overseas with them is it safe to plug them into a simple travel plug adapter?

Does using a travel adapter cause the device to charge slower?

Could using a travel adapter damage the original charger?

Apple chargers will automatically sense and handle either 110 or 220. Your brick will work overseas with the right adaptor. They used to sell a “world kit” that may or may not be still available.

Adapters are designed to work with either 110-120 V @ 60Hz or 220-230 V @ 50Hz. However, the issue is the prongs the hook in. Some hotels offer multi-standard outlets, while others loan you an adapter.

The Apple charger (unless it's a very old charger) will be fine.

For example, my 5W Apple charger (manufactured in 2009!) states:
Input voltage: 100 - 240V
Input Frequency: 50-60Hz.

That will cover you right across the world for the various voltage and frequency combinations (ie 110V/60Hz found in North America, Parts of South America and half of Japan, 110V/50Hz found in the other half of Japan, 230V/50Hz found in Europe, majority of Middle Eastern countries, parts of South America and majority of Asia, and 230V/60Hz found in a few places like Saudi Arabia, Peru and the Philippines).

New chargers will be no different. The key for you will be to have a socket adapter that suits the country you're traveling to...
