When I was in London, my hotel bathroom has a recep like this. But my understanding of that particular device was that it had a transformer built in. It wouldn’t power my wife’s hairdryer but it would charge my beard trimmer. It’s called a shaver receptacle. But the one I linked is hardwired for 120 or 240.
It’s power-limited. Commonly called a “shaver receptacle.”
In the UK, bathrooms have no normal electrical power other than the light fixture and possibly a towel warmer. Even the light switch is usually outside the door.
@Besoeker3 could probably provide a more accurate depiction.
