I believe dryer outlets are typically 30a@240v. That’s a nice step up than a standard outlet and simple math shows 4x the power of 15a@120v

If you have one in your garage, then you already have an outlet that can do faster charging than a standard outlet.

Just like you technically don’t need a 50a level 2 charger, you may not have to settle for a standard outlet. I bought a heavy duty extension cable with adapters for several different outlet types.
