I don't have a type 2 charger for my Tesla or my leaf, which I've had for over 7 years now. So here's some facts -
If you're not doing a huge amount of driving - say less than 60 miles a day and there's a rapid charger somewhere near if you do ever need to top up, then the granny lead is absolutely fine for charging, and you can get by without a dedicated charger.
Anyone saying they are "safe" to just plug in and walk away is wrong. The chargers are fine, and yes a socket is "rated" for more power, but I have melted two plug sockets in my 7 years both times I would class as dangerous, and both were avoidable if I'd stayed long enough to monitor the plug temperature. The current draw on the socket is not the issue, it's the contact that the plug makes to the socket or the wires in the socket not being correctly torqued that's the issue. The issue is you can't see from the outside of a socket if the contacts are a bit loose/dirty or if the connectors weren't tightened. The poor contact causes heat, which causes increased resistance, which causes heat.... etc etc
So make sure you have a reliable socket and wiring and you'll be fine. If I'm visiting somewhere and I'm not confident the socket is good or I'm using an extension lead you can knock the charge current down to 8A or less in the app if you're in no rush.
One thing to consider now the grant's gone is the Tesla "Granny charger" can pull 32A if you buy the 32A euro connector from Tesla and have a 32A socket installed at home. This would still need the correct DC protected circuit breaker fitting (as it would be a dedicated charging point) and they're about £100.
