What is the difference between Level 1, Level 2 and DC fast charging?

Level 1 uses a standard 120-volt household outlet and adds only a few miles of range per hour, which can still work for short daily commutes. Level 2 uses a 240-volt circuit, like a dryer outlet, at home or public stations, and can typically refill most EVs overnight. DC fast charging uses high-power public stations that can add substantial range in well under an hour, best for road trips. Actual speeds depend on the vehicle and charger.
