As TexasEV indicated, the cord that you use to connect the car to a wall isn't a charger cord, it is a really expensive extension cord.
The cord that some with the
car (UMC) is suitable for plugging into many different plugs and may solve all of your issues. If your plug doesn't match the cord, then you may could get one of the
adapters for the cable (and other locations).
So you can use the cable, plug in, and charge. If you look at the page with the adapters, you will see a chart indicating how fast each one will charge the car. As you can see, that basic 120V wall plug (5-15) doesn't add that many miles. In 12 hours, only about 36 miles. If that is enough for you, then great. But if it isn't then you need more power. That's when an electrician comes in. The
Tesla Wall connector is overkill for most folks, but does make for a pretty installation.
I personally already had a 14-50 plug installed, that I had for my Leaf. I just bought a 2nd mobile UMC and leave one on the wall and one in the car.
The car also includes the
J1772 adapter which allows you to charge off of any Level 2 chargers, which are all over the place.

The Tesla plug is unique to Tesla, so if you have or are thinking of any other EV, then the Tesla Wall Connector may not be the best alternative.
