Hi. By accident I found out that OEM charger supports 220V, despite marked only for 110V.
And it charges the car very fast. Full charge in 2.5 hr.
I found this out by accident. Our garage in on the same fuse as bathrooms and it always blew, when the car was charging and someone would switch on the hair dryer.
The only other mains on separate fuse was garage heater and I thought I will split the mains from the heater into a separate socket for charging. I was convinced it is 110V circuit and did that. Installed simple 115V socket.
Noticed immediately how the car started charging much faster.
Only a few weeks later, I realised that it was actually a 220V circuit! Now I been using the OEM charger on 220V circuit for couple of months without issues.
Spared me $400 from buying separate charger for 220V.
