If you’re considering a Tesla or already own one, charging compatibility is likely on your mind. While Tesla has its proprietary charging network, many public and home chargers use the J1772 standard.
So, do Teslas come with a J1772 adapter, or is it something you need to purchase separately? In this article, we’ll break down what’s included with your Tesla, how the J1772 adapter works, and whether you need one for your charging needs.
What Is a J1772 Adapter?
The SAE J1772 connector is the standard charging plug used by most non-Tesla electric vehicles in North America. It is commonly found at public Level 2 charging stations. Since Tesla uses its proprietary charging connector, a J1772 adapter is required for Tesla owners who want to use these public chargers.
A J1772 adapter allows Tesla vehicles to connect to J1772-equipped charging stations, ensuring greater charging flexibility, especially in areas where Tesla Superchargers or Destination Chargers are not available.
Do Teslas Include a J1772 Adapter?
Tesla has historically included a J1772 adapter with its vehicles, but recent changes in Tesla’s charging accessory policy mean that newer Tesla purchases may or may not come with one. Here’s a breakdown:
-
Older Tesla Models: Previously, Tesla provided a J1772 adapter as part of the standard accessory package with every new vehicle.
-
Recent Models (2022 and Later): In recent years, Tesla has stopped including certain charging accessories, including the Mobile Connector, by default. While some models may still include a J1772 adapter, new buyers should check their specific configuration at the time of purchase.
If your Tesla did not come with a J1772 adapter, it is available for purchase separately from Tesla’s official store or third-party retailers.
How to Use a J1772 Adapter with a Tesla?
Using a J1772 adapter to charge your Tesla is quick and easy. Follow these steps:
-
Connect the Adapter – Take your Tesla J1772 adapter and firmly attach it to the J1772 charging connector. Ensure it clicks into place.
-
Plug into Your Tesla – Insert the adapter (with the J1772 cable attached) into your Tesla’s charging port. The port light should turn blue, indicating a successful connection.
-
Start Charging – Wait for the port light to turn green, signaling that charging has begun. You can also check the charging status on the Tesla app or vehicle touchscreen.
-
Stop and Disconnect – When charging is complete, unlock the charging port via the Tesla app, car touchscreen, or by pressing the button on the charging handle (if available).
-
Remove and Store – First, unplug the adapter from your Tesla, then detach the J1772 connector from the adapter. Store the adapter in a dry and secure place for future use.
This step-by-step breakdown ensures a smooth charging experience and prevents unnecessary wear on the adapter and charging port.
Where to Buy a J1772 Adapter
If your Tesla did not include a J1772 adapter, you can purchase one from:
Tesla’s Official Store: Tesla sells an official J1772 adapter that supports up to 80 amps.
Third-Party Retailers: Various online marketplaces offer J1772 adapters, but it’s important to check for compatibility and quality before purchasing.
Why You Might Need a J1772 Adapter?
Although Tesla has an extensive Supercharger network, having the J1772 adapter can make your EV charging experience even more convenient for some reasons:
Compatibility with more public charging stations: Many shopping malls, office buildings, hotels, and municipal parking lots have charging stations that use the J1772 standard that Tesla’s charging ports can’t directly connect to. With an adapter, you can use these charging facilities whenever you want, without being limited by incompatible charging stations.
Increased charging flexibility at home: If you already have a J1772-compliant Level 2 charger at home, such as a MOREDAY, ChargePoint or JuiceBox, you can use the adapter to charge your Tesla directly without having to purchase an additional Tesla wall connector, saving you money.
Peace of mind on long trips: In some areas, where Tesla Superchargers are fewer in number, J1772 charging posts are more common. Carrying the J1772 adapter with you means you have more flexibility in finding available charging stations when you’re on the road and less mileage anxiety.
Conclusion
Most Teslas traditionally came with a J1772 adapter, but this has changed in recent years. If you are purchasing a new Tesla, it’s recommended to confirm whether an adapter is included and, if not, consider buying one separately.
A J1772 adapter enhances charging flexibility, making it a useful accessory for Tesla owners who frequently rely on public or non-Tesla charging stations.
Frequently Asked Questions
1. Can I use a J1772 adapter for DC fast charging?
No, J1772 adapters are only for Level 1 and Level 2 AC charging. For DC fast charging, Tesla vehicles use the Supercharger network or require a CCS adapter for non-Tesla fast chargers.
2. How long does it take to charge a Tesla using a J1772 adapter?
Charging speed depends on the Level 2 charger’s power output. Typically, a 32-amp Level 2 charger can add about 25-30 miles of range per hour, while higher-powered stations can provide more.
3. Is the J1772 adapter waterproof?
Yes, Tesla’s official J1772 adapter is designed to be weather-resistant, meaning it can withstand rain and general outdoor conditions.
However, it is not fully waterproof, so prolonged exposure to heavy rain, snow, or standing water should be avoided. To extend its lifespan, it’s best to store the adapter in a dry place when not in use.
4. Can I leave the J1772 adapter plugged in all the time?
While you technically can leave the J1772 adapter connected to your charging cable, it’s recommended to unplug it when not in use. Keeping it plugged in continuously may lead to unnecessary wear and tear on the connector pins, increasing the risk of loose connections over time.
Additionally, unplugging it helps protect against dirt, moisture, and accidental damage, ensuring a longer lifespan for both the adapter and your charging equipment.
