International Adapters and Voltage Converter

You will not need a voltage adapter.

If you could tell us what countries you will be visiting, we can tell you which wall plug adapters you will need.

The Apple Travel kit is nice, but you only really get one adapter that will work in the region in which you are visiting. Most of us need 3-4 adapters to run the phones, laptop, iPad, razor, etc.

Also, before using anything, it is always good practice to check the label/text on a power adapter/charger (and electrical equipment generally) for information about the input voltage and frequency. This can be difficult to find or read, so you may need a magnifying glass. For example, a modern Apple power adapter would typically have an input voltage range of something like 100-240 V AC at 50/60 Hz.

All Apple iPad USB power adapters are designed for use with power sources rated to provide 100V AC to 240V AC at 50Hz to 60Hz. Apple iPad USB power adapters also comply with the IEC/UL 60950-1 and IEC/UL 62368-1 standards for use with power sources rated to provide 115V AC at 400Hz (typically found onboard commercial airlines).

While your Power Adapter will be fully usable when travelling internationally, you may require a simple pin-adapter to allow the Power Adapter to be used with AC power outlets in different countries. By example, a US flat 2-pin connector will require an adapter for the standard European round 2-pin socket - or UK 3-pin square socket. Travel adapters are readily available at Airports and many electrical retailers.

Be aware that Apple's Travel Kit is limited in that the adapters are only useable with Apple's Power Adapters that have interchangeable duck-heads - whereas regular pin-adapters are both cheaper and potentially useful with many more items that you may be carrying on your travels.

I am assuming that you have a U.S. type plug on your MacBook Air, iPhone and other devices.

Kenya, Dubai, Tanzania and Seychelles all use what is known as a Type G plug / adapter.

Amazon has them.

If using Apple provided charge cubes, you would simply need an appropriate plug adapter for the local power system.

Apple chargers support 110V to 240V. You wouldn’t need a voltage adapter. Only an adapter that allows you to plug in locally.
