Standard wall outlet. Extremely slow, adding 3-5 miles of range per hour. Best for overnight plug-ins if you drive very little.

Home wallbox or public stations (like ChargePoint). Adds 20-40 miles of range per hour. The standard for daily charging.

Tesla Superchargers or Electrify America. Can fill 10% to 80% in 20-40 minutes. Slows down significantly after 80% to protect the battery.
