Charging electric cars on Club sites.

Your plug may well get warm simply because the charger is inbuilt with the 3 pin plug, heat dissipation has to go somewhere.

In the case of EV portable chargers it is a 13a 3 pin plug only, the charger limited to 2kW or 3kW is on a length of this lead and out of the charger are heavier leads that then has a socket to plug into the car.

On saying that, I would not even be happy to leave the phone or tablet type charger on overnight in the caravan, especially if it came from the 'Poundshop'

yes same here

Does not or does?

Mine get hot.

My chargers gets hot and it's not a cheap pound land one, PLUS I would never leave any charger on unattended.

On my laptop, the plug does not get hot but the transformer thing on the cable does.  Makes a good hand warmer!

When we use a 2kw fan heater the plug on it can get warm, that would be about the same power as charging an EV would use.

We have an 3 socket 13amp extension cable that we used in  lounge, we keep the small fan  heater there for occasional use if it is cold in the day and we do not want to turn on the CH.

After leaving it plugged in for a long time, but only using occasionally, I found the plug had become "welded" into the socket!   These were not cheap Chinese appliances.

To get it free I had to destroy the one socket, the other 2 were fine.  It was rather worrying.  We now unplug the heater when not in use.

I had similar in a caravan. The fault was due to a new but faulty extension - not a cheap one either. I had to replace the caravan 13amp socket

I'm sure a new EV would have all kinds of safety measures built into it. These things are inspected and tested rigorously.

As long as ALL your caravan wiring and sockets are good I would hope that the piece you are plugging into the caravan will be OK. I needing to use an extension I would make my own using cable rated to 16amp.

Most things these days are "tested under test conditions" then they are released into the real world,  The "problems" appear when joe public gets their hands on them
