Voltage converter

[AC Question]

I understand that I-phones convert internally from 110 to 220. No need for a converter.
All you need a wall adapter.
Do Android phones have auto-internal converter from 110 t0 220 ?

Welcome to Android Central! All modern devices come with a charger that is compatible with 110V and 220V. If you're not sure, just look at the charger's fine print, and make sure it says 110-220V.

I believe it's the same for the iPhone. It has to do with the charger, not the internal circuitry.
