The charger socket might be a type 2, but the PHEV needs a type 1, hence the type 2 to type 1 cable. But again, that will only supply 3.6kW AC, rather than the 45kW that some cars can take. Those are more designed as destination chargers where you aim to park for hours.
But it's much more likely to be a DC charger, with both CCS and Chademo cables wired into the charger. The PHEV uses Chademo, whereas the European standard now seems to be CCS
Chademo will give you a charge to 80% (6kWh) in around 20 minutes.
There have been several reports on here and on other forums about overheating granny chargers. You may well be lucky, but all it takes is some corrosion between to connections anywhere in the circuit and you will get heat, which can cause more corrosion. 10A at 230V can generate a lot of heat if there's a poor connection. You can also search for perfectly adequate extension leads where people haven't bothered to unwind them and the normal heating at 10A causes the cable to melt. There are also plenty of pictures of burnt plugs and burnt sockets, though which triggers which isn't always clear. I'm not saying it will happen, but it definitely happens to some people. I stopped using mine when the plug got too hot over one summer.
And I'm afraid you'll be lucky if it's covered - few people have succeeded in getting their cable replaced under warranty.
