  "summary": "The North American Charging Standard, standardized by SAE as J3400. Physically the connector Tesla used for years, now adopted by nearly every automaker for the North American market. A single pair of pins carries both AC (Level 1/2) and DC fast charging, which is why the plug is smaller and lighter than CCS1.",

  "notes": "From the 2025 model year onward most new EVs in North America ship with a native NACS port. Older CCS1 cars reach NACS chargers (like Tesla Superchargers) with a NACS-to-CCS1 adapter."
