There are two version. 110 and 220. You can either choose one when purchasing. However, the adaptor that connect to the charger itself can be interchanged. You can buy two different type of adaptor (110 and 220) and use accordingly. Alternatively, there is a car adaptor coming with the charger too, all car in the world is having same 12V in the cigrette lighter compartment.
