The regular socket for a reading lamp can be used to charge and EV. The is called Level 1 charging. It is a very slow way to charge sometimes taking up to 20 hours for a full charge.
The big socket like for the clothes dryer is called level 2 charging. It is much faster than Level 1 taking 4 to 6 hours for a full charge. Usually used to charge over night.
Then is the Level 3 DC fast chargers. They can give a full charge to Tesla in as little as a half hour. There are thousands of Tesla Supercharger stations in the USA...but they only work on Teslas.
