What this means
Level 2 is the standard public and home charger (240V) — a few hours for a full charge, fine for shopping, work, or overnight. DC fast charging is the highway kind: 20–40 minutes to most of a charge, but not every station has it.
Connectors are the plug shape. J1772 is the universal Level 2 plug almost every non-Tesla EV uses. CCS and CHAdeMO are DC fast-charging plugs (CHAdeMO is older, mostly older Nissan Leafs). NACS is Tesla's plug, now the emerging US standard — many newer non-Teslas use it or an adapter.
This page summarizes NREL's own station records and is not a live availability map — a charger listed here can still be busy, broken, or behind a gate. Check the network's app before you rely on a specific plug.
