If you own two or three Tesla Models, installing a Tesla super wall charger is mandatory. You will require simultaneous charging solutions for charging two to three Tesla Models at the same time. That is when the Tesla wall charger tends to bring the most convenient experience.

Therefore, when you really want to save your budget, the NEMA 14-50 should bring the most convenient experience.

The NEMA 14-50 adapter charges at 32 amps max, whereas the wall charger charges at 48 amps

When it comes to fast charging, the Tesla wall charger should give you the fastest experience. But when you are thinking about charging your Tesla at home, you probably will plug the charger overnight.

It is indeed true that using the NEMA 14-50 charging adapter will take a little longer time to fully charge a Tesla high-range model. But if the charging time does not matter to you, you can get away with the adapter or mobile charger as well.

NEMA 14-50 has some limitations

Especially, when you are using a long-range Tesla, you may need to charge the vehicle with a 60-amp circuit which is not compatible with the NEMA adapter. But when you have the Tesla high-power wall charger, you will have the option to adjust the amp connection so that you can get the appropriate amount of charging.

Which is the best option for you?

For a single Tesla user, the NEMA 14-50 charging receptacle is the best option for you. On the other hand, choose the Tesla high-power wall charger when you have multiple Tesla models with a Tesla featured garage.
