You can do it and it will probably be fine but there is a higher risk you’ll melt something. I’ve seen a lot more melted sockets from granny chargers than I have wall boxes but it that way.
It only takes one weak link to cause a problem and the weak link is usually the plug socket. New sockets are fine and reduce that risk but they wear out over time and they will probably melt eventually.
The other thing to think about is time of use tariffs, it’s much harder to take advantage of short periods overnight which are the cheap rate if you can’t get the power into the car in that window.
A note to add here is that if you buy a tesla, then the granny charger cable has a "hot swappable" (by that i mean it plugs in there is no wiring to do) plug you can change from normal 13 amp plug to 16 or 32 amp commando and it will allow the relevant amp flow automatically.
Thats why I went with a basic exterior 32 amp wall socket rather than some dedicated wall "charger"
