What type of power outlet is needed to charge an Audi e-Tron at home?

I am interested in purchasing an Audi e-Tron and want to know what type of power outlet is required for at-home charging. I am also curious about the charging time for a fully depleted battery with this type of outlet.

The Audi e-Tron can be charged at home using a standard 120V household outlet, but this will result in a longer charging time. To fully charge the battery, it is recommended to use a 240V outlet, which can be installed by a certified electrician for faster and more efficient charging.
