[Android Central Question]

If one travels to Europe, Asia, Caribbean do you need a voltage converter?

No such converter is needed.

Welcome to Android Central! Pretty much all smart devices these days come with a charging plug that's dual voltage. Just look at the fine print on the plug -- if it says 110-220V, that means it's compatible with both.

If not using a convertor, you will need a plug convertor.

The phone is one voltage - 5 Volts DC.

The power supply (the thing you plug into the wall [the charger is actually a little chip on the motherboard]) is almost always 95-230 Volts, 50.60 Hz, so it's usable world-wide but, as methodman said, different parts of the world use different wall outlet types, so you need a universal plug adapter - this one should do it. (Since it's not a voltage converter, just a plug adapter, it can handle up to 3,000 Watts.)
