    fast charging requires a larger service connection than a wall outlet. you can slow charge from a normal wall outlet, but it will take ages to fully charge a modest battery.

    generally people have it installed by an electrician, running a new conduit from the circuit breaker.

      For home charging to keep up with a commute, a normal wall outlet all night long is fine. It just needs to be installed where the car is parked, and it should have some protection from weather while the car is plugged in.

      220V? Better than 30A? I’m asking what I would need to install in my home. I have no clue on this.

        In the us, home chargers will typically run on 240 volts, similar to a dryer or electric stove.

        The amperage can be as low as 16 amps (not common) and up to 40 amps. There are higher amperage chargers, but they’re not super common. Most homes dont have that much capacity provisioned and adding it to the breaker box means new circuits and often the power company has to provide a higher capacity meter. It gets expensive.

        Since volts x amps = watts, a 240 volt charger that operates at 40 amps will charge at 9600 watts or 9.6 kilowatts (maximum).

        You can charge using a standard 120v outlet, most are rated for 15 amps. However, you will get 120v x 15a = 1800 watts or 1.8 kilowatts (maximum).

        talk to an electrician after looking at the specs on the charger you want. I’m not qualified to give you electrical instructions
