EV Charging Connector Types Explained — J1772, CCS, and Tesla NACS
Electric vehicles in North America use three primary charging connector standards:
J1772, CCS, and Tesla NACS.
Understanding each plug type helps EV owners choose the right charger, handle compatibility issues,
and plan for home and public charging.
✔ As of 2024–2025, most major automakers in North America are transitioning to Tesla’s NACS connector,
making it the future standard for EV charging.

2. J1772 Connector Explained
J1772 is the standard AC charging connector used by nearly all non-Tesla electric vehicles in North America.
Every Level 1 and Level 2 public charger (non-Tesla) uses this connector.
Key Features
- Supports 120V (Level 1) and 240V (Level 2)
- Max power typically 7.2 kW–19 kW depending on charger
- Large, durable connector designed for everyday use
- Tesla vehicles can use J1772 with an adapter
Who Uses J1772?
- Chevrolet Bolt
- Nissan Leaf
- Ford Mach-E (until 2025)
- Volkswagen ID.4
- Hyundai / Kia EVs
- Most other EV brands pre-2025
3. CCS Connector Explained
CCS (Combined Charging System) is a hybrid connector that combines the J1772 AC port
with two additional DC pins, enabling both AC charging and ultra-fast DC charging.
Key Features
- Supports both Level 2 and DC Fast Charging
- Commonly used by Electrify America, EVgo, and other fast chargers
- Can deliver 50 kW up to 350 kW depending on charger
- Used by most U.S. EVs until transition to NACS
Who Uses CCS?
- Ford EVs (until 2025)
- Volkswagen Group EVs
- BMW, Mercedes-Benz
- Hyundai Ioniq & Kia EV series
- Rivian
- Lucid (transitioning)
CCS is currently the dominant DC fast charging connector in North America,
but will gradually shift toward NACS beginning in 2025.
4. Tesla NACS Connector Explained
Tesla’s NACS (North American Charging Standard) connector is compact, lightweight,
and supports both AC Level 2 and DC Supercharging.
In 2023–2024, most major automakers adopted NACS as their future standard.
Key Features
- Smallest and simplest connector design
- Supports Level 1, Level 2, and DC Fast Charging (up to 1 MW future potential)
- Compatible with all Tesla home chargers
- Will be supported by future EV models (Ford, GM, Rivian, etc.)
Who Uses NACS?
- Tesla (Model 3, Y, S, X)
- Ford EVs (2025+)
- GM EVs (2025+)
- Rivian
- Volvo & Polestar
- Nearly all brands by 2026
NACS will become the universal EV connector in North America by 2026.

5. Compatibility and Adapters
Tesla → J1772 Adapter
- Allows Tesla chargers to charge non-Tesla EVs
- Common for home Level 2 charging
J1772 → Tesla Adapter
- Included with most Tesla vehicles
- Allows Tesla owners to use public Level 2 stations
CCS to Tesla Adapter
- Enables CCS fast chargers to charge Tesla vehicles
- Useful in regions lacking Superchargers
NACS Adapters for 2025+ Vehicles
Most automakers will provide adapters for older EVs until native NACS ports become standard.
6. Which Connector Should You Choose?
- If you own a Tesla: NACS is your primary connector.
- If you own a non-Tesla EV: J1772 for home, CCS for fast charging.
- If you plan to buy an EV in 2025+: Expect NACS to be standard.
Choosing a charger with the right connector ensures compatibility and avoids relying on adapters.
7. Summary
J1772, CCS, and NACS each play an important role in EV charging.
J1772 is the universal AC connector, CCS provides high-speed DC charging,
and NACS represents the future unified standard.
Understanding their differences helps ensure correct charger selection and compatibility
with current and future EVs.
