J1772 and CHAdeMO: The Other Two EV Plugs Explained

The plug story most drivers hear stops at NACS versus CCS1, but two other connectors complete the picture: one so successful it is invisible, one so early it is being retired. If you drive anything from a base Leaf to a new NACS car with an adapter bag, this is the rest of the map.

J1772: The Connector That Won by Disappearing

J1772 has been the North American AC charging standard since 2010. Every non-Tesla EV carries the round five-pin port, every public Level 2 station hangs the matching plug, and the top half of every CCS1 port is literally a J1772 socket. It covers Level 1 at about 1.4 kW and Level 2 up to 19.2 kW, and it does its job so uneventfully that most owners never learn its name.

Three practical J1772 facts worth keeping:

• Any J1772 station charges any CCS1 car at Level 2, no adapter needed, because the AC pins are the same pins.
• NACS cars use J1772 stations through the small AC adapter that ships with the car, so home and hotel chargers work for everyone.
• J1772's successor is the AC side of NACS under the J3400 standard, but the millions of existing J1772 plugs will serve for many years, exactly like the Level 2 routines covered in our battery guides.

CHAdeMO: The Pioneer Running Out of Road

CHAdeMO was doing DC fast charging before CCS existed, and the Nissan Leaf built its case on it. In North America it typically delivers around 50 kW, which was quick in 2013 and is modest now. The harder problem is coverage: networks rarely install new CHAdeMO plugs, older ones retire without replacement, and the connector often gets one stall per site while CCS1 and NACS get the rest.

For South Florida Leaf drivers the playbook is straightforward: know your two or three dependable CHAdeMO stops, lean on Level 2 for daily charging since the J1772 side is unaffected, and keep a rescue plan for the day the one working CHAdeMO stall is occupied or offline. Nissan itself moved on, putting CCS1 on the Ariya and NACS on what follows.

How the Four Plugs Fit Together

Think of it as two eras stacked on each other. The AC layer is J1772 plus the AC mode of NACS: mature, universal, boring in the best way. The DC layer is where the change happened: CHAdeMO pioneered it, CCS1 industrialized it, and NACS consolidated it, a transition our NACS vs CCS1 guide traces in full. Which port your specific car carries is mapped in the brand-by-brand guide.
