what voltage comes out of a wall outlet
Mains electricity The two principal properties of the electric power supply, voltage and frequency, differ between regions. A voltage of (nominally) 230 V and a frequency of 50 Hz is used in Europe, most of Africa, most of Asia, much of South America and Australia. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other voltages exist, and some countries may have, for example, 230 V but 60 Hz. This is a concern to travelers, since portable appliances designed for one voltage and frequency combination may not operate with, or may even be destroyed by another. The use of different and incompatible plugs and sockets in different regions and countries provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.
Tesla Model S Tesla recommends that the primary method of charging be overnight charging at home, "just like your mobile phone". Tesla Model S vehicles come with the Mobile Connector, which allows charging at up to 40 amps and includes adapters for connecting to a variety of electricity sources.[214] In North America, adapters for 120-volt NEMA 5-15 and 240-volt NEMA 14-50 outlets, as well as an adapter for SAE J1772 charging stations, are included.[214] In Europe, adapters for CEE red 3P+N+E, CEE blue 2P+E, CEE 7, and BS 1363 are available (inclusion varies by country), and an adapter cable for connecting to chargers with a Type 2 connector is also included.[215][216]
