This is really cool! It's an interesting look at all the subtle difference between England and USA or Canada.
There's one problem though. No, everything will not work with nothing more than a plug adapter! Just try it out for yourself! You also need a power converter because the UK uses 240V and 50Hz, whereas North America uses 110V and 60Hz.
I guess a lot of electronics now run on DC power and their power bricks will work between 100V and 240V, but those are the only devices that will not get fried.
Pretty much every phone and laptop is multi voltage.
But for some reason other things you might travel with, like shavers, trimmers, hair dryers and hair straighteners aren't.
More of a problem for women than men, but annoying.
