I find that public chargers (including those in the workplace) can vary quite a lot as some of the units have to share a supply so even though advertised at 7kW or even 16kW, they may be supplying a lot less. Plus you need to remember that regardless of the power of the charger, the car can only charge at 3.7kW max so anything more than that makes no difference.
So I have a 7kW unit at home that obviously isn't shared so my car can pull the maximum of 3.7kW all day long and I find it takes around 2.5 hours depending on things like temperature etc
It's fine as long as your wiring meets modern standards.
If you have old or questionable electrics then might be worth getting it checked but there are other household appliances that pull just as much load for just as long
Agreed. We've been charging ours daily (sometimes twice daily) for two and a half years off a 13A socket. There's a temperature sensor in the cable which will shut off the charge if it detects overheating at the plug/socket. Important to ensure the socket is in good condition - cheap as chips to replace if you're in any doubt. Bear in mind the plug wiring is thick and not very bendy when you consider where you're going to use it. An outside socket would be better.
