In everyday use, yes. “Level 3” is a common informal name for DC fast charging in North America. However, the main standards and US government sources usually say “DC fast charging” instead, because “Level 3” was used in early drafts for different things. If you see “Level 3 charger” at a station or in an article, it means a DC fast charger.
Charging Levels Compared
| Level | Power | Range per hour (DOT) | Connectors |

| Level 2 | 7–19 kW | 10–20 miles | J1772, NACS |
| DC fast (“Level 3”) | 50–350 kW | 180–240 miles | CCS1, NACS, CHAdeMO |
Ranges are DOT estimates; actual numbers depend on the car.
Can You Install Level 3 at Home?

DC Hardware for Businesses
For commercial sites that want DC without a very large connection, compact units such as the EVDANCE EV-RHDC30K-L compact DC fast charger are an option. See how DC fast chargers work.
