General
What are the three types of EV chargers?
Home and public charging is commonly grouped as Level 1, Level 2, and DC fast charging (often called Level 3 in casual talk).
Most homes use Level 2 for overnight charging.
Quick comparison
Level 1 uses a standard household outlet and charges slowly.
Level 2 uses 240V and is the usual home upgrade.
DC fast charging is mainly for public corridor charging, not a typical garage install.
