Where?
Australasia (except WA) & most of Europe is 230V
Other bits of Europe and most of Asia is 220Nearly all of the americas (north, central and south) are 120V
(In reality the standards are all +/- such a big tolerance that you might actually be getting as low as 215 or as high as 250V on a particular phase at a particular time, and all modern power supplies will run happily anywhere in this range, as I say this is pure pedantry)
To be a pedant, pretty much nowhere in the developed world uses 240V now.
You’d need to run an extension lead either from Perth, or through a time portal from 2000.
