You can charge a Tesla at home by plugging into the regular outlets of 120 V AC using a NEMA 5-15 adapter. It is a slow process.

To speed up you can set up a NEMA 14-50 outlet in your home to charge your Tesla with the corresponding adapter. But the best and efficient way to charge is to set up a wall connector.

Using A NEMA 5-15 Adapter:

It requires regular home outlets. All you need is to plug your NEMA 5-15 adapter into the regular outlet and connect it to your Tesla. It will start charging. This is the easiest method since you do not need any extra installations. But it will only give you a range of about 3-4 miles of range per hour of charging.

Using A NEMA 14-50 Adapter:

It uses a 4 prong outlet that provides a 240 Volts AC supply. After wiring the outlet in your house you can use it to charge your Tesla using the NEMA 14-50 charger that comes with your car. It is a comparatively fast charger than the previous one. It gives a range of 20-30 miles per hour of charging.

Using A Wall Connector:

The most efficient way to charge a Tesla at home is to install a Wall Connector (Tesla wall connector installation). It is a special feature from Tesla. You have to buy a wall connector and get an electrician to install it. It provides 240 Volts AC and a better current supply than the NEMA 14-50 adapters. It gives a range of 30-40 miles per hour of charging.

How Long Does It Take To Charge A Tesla At Home?

Using a regular home outlet and a NEMA 5-15 adapter it will take about 3-4 days to charge your Tesla depending on the model you are charging.

Using a NEMA 14-50 adapter will reduce the charging period to 15-17 hours. Tesla silver Wall Connector will charge even faster. It will take about 7-8 hours to charge your Tesla fully.

What Is The Tesla Home Charger Price?

The NEMA 5-15 is included in the Car package. So, it is free and does not need any installations cost either. If your car does not come with a level 2 adapter like NEMA 15-50, you will have to buy one which will cost 45 $. And a wall connector costs 500 $. Both of these needs an installation cost of 750-1500 $.

Since the NEMA 5-15 is a very slow charging method it is better to use a NEMA 15-50 or a wall connector despite the price that comes with it.
