Not allowed in the USA? Maybe so, but on a recent trip there I was surprised to see these installed in a coach (Megabus) for the purpose of passengers charging their phones and tablets.

Charging points at Heathrow and Gatwick have UK and Schuko next to each other nowadays.

Rather dangerous thing to do. There are still homes with 5 amp round pin sockets often for portable lightning all controlled by a single switch. Nothing to stop someone plugging in one of their 24v DC appliances.

There was a similar problem in Australia where portable generators were being sold with a 12 volt 2 pin socket with the same outline as the 2 business pins of their standard 240 volt socket (I've seen them here as well). The authorities soon put a stop to that with a recall and generators there now have the standard Australian low voltage (ELV here) 2 pin socket which has the 2 pins at right angles to each other.
