You will likely find it easier and less costly to just get a NEMA 14-50 plug installed in your garage. All electricians will know how to do this and you don't even need to tell them it is for a Tesla. It is basically a dryer plug. They will charge more as soon as they hear Tesla.
Then buy the NEMA 14-50 adaptor for the mobile charger that comes with the car or many other changers can plug directly into the NEMA 14-50 outlet.
Gen 2 NEMA Adapters
Downside is the wall connector will do 48 amps Versus 40 amps for anything using the NEMA 14-50 Plug. If you use a 3rd party charger you will need to use the adaptor for the car and you will not have the button on the charger handle to open the car charger port.
I have this one and enjoy that it has WIFI connectivity to collect charging stats and adjust the charging speed if you are trying to keep the charging going at a slow pace during winter to keep the battery warm.

The NEMA 14-50 plug is probably the most flexible solution and will allow you to pick whatever charger you want in the future.
