As electric vehicles (EVs) continue to become more mainstream, choosing the right home charger is no longer just about charging speed — it also means selecting the connector standard that best matches your vehicle today and in the years ahead.
With more automakers transitioning toward Tesla's North American Charging Standard (NACS) while millions of existing EVs continue using J1772, buyers now face an important decision when purchasing a new charger.
What is NACS?
The NACS was originally developed by Tesla as its proprietary charging connector before being opened to the wider automotive industry.
Today, it is rapidly becoming one of the most influential charging standards in North America as major manufacturers continue adopting it for future electric vehicle lineups.
Unlike traditional charging connectors, NACS supports both Level 2 AC home charging and DC fast charging using the same compact connector.
Key features of NACS
- Supports both AC home charging and DC fast charging
- Native access to Tesla's extensive Supercharger network for compatible vehicles
- Increasing support from major automakers, making it more future-proof
What is J1772?
The SAE J1772 connector has long been the standard charging interface for nearly every non-Tesla EV sold in North America.
It supports both Level 1 and Level 2 AC charging, making it the most common connector found on residential chargers and public AC charging stations.
Although J1772 does not support DC fast charging directly, it remains the preferred choice for millions of existing EV owners due to its broad compatibility.
Key features of J1772
- Compatible with most non-Tesla EVs
- Widely supported across existing home and public charging infrastructure
- Home chargers are generally more affordable
Which charging standard is growing faster?
One of the biggest developments in the EV industry over the past two years has been the rapid adoption of NACS.
Several major automakers — including Ford, General Motors, and Rivian — have announced plans to transition future EVs to Tesla's charging connector.
That said, J1772 isn't disappearing anytime soon. Millions of vehicles currently on the road still use the connector, and most existing residential chargers and public Level 2 stations continue to rely on the J1772 standard.
Which EV charging standard should you choose?
The right choice depends largely on the vehicle you own — or are planning to buy in the future.
If you're driving a Tesla or intend to purchase a new EV from a manufacturer adopting the NACS standard, investing in a NACS-compatible charger offers greater long-term convenience.
Meanwhile, J1772 remains the practical choice for owners of current non-Tesla electric vehicles.
