alt Hacker NewsWhat are you going to plug into a power outlet on an airplane that isn't dual voltage? A kettle or a toaster? I assume they have a way of preventing people from using those.
Almost all the international flights I've flown have had power outlets, always between 220V and 110V countries (heck, only Japan is 110V besides the US as far as I know).
I it works for China because they use (as an option at least) similar outlets to the USA (just ungrounded, pop).

I think 'assuming that the airline has a way of preventing' people from plugging in dangerous items is doing a loooooot of heavy lifting in your argument.
How, exactly? The airlines have absolutely no way to know what shoddy electrical device you bought god-knows-where you're plugging into mains power in their airtight travel-coffin, packed with hundreds of people, hurtling across some ocean.

Seems deeply unusual to me, but I won't dispute your experiences. I've flown internationally fairly often, and in my experience power outlets are rather uncommon (at least in the eastern hemisphere, flights to/from the Americas may differ, I haven't flown around there for many years).

Japan is an oddball by being 100V.
US is 120 and that extends pretty far south (and north).

I’m semi amazed motor vehicles are as standard as they are with 12V and the same socket worldwide. I guess the tobacco industry is a great unifier.
