What is a J1772 charger?

A J1772 charger refers to an EV charger that uses the SAE J1772 connector, which is the standard AC charging interface for most electric vehicles in North America.

J1772 connectors are commonly used for both Level 1 and Level 2 AC charging and are supported by the majority of non-Tesla EVs.

Is my EV compatible with a J1772 charger?

Most electric vehicles sold in North America are compatible with J1772 charging. This includes many battery electric vehicles (BEVs) and plug-in hybrids (PHEVs).

Vehicles that use a different native connector may still be able to charge with a J1772 charger when using an approved adapter.

What’s the difference between Level 2 chargers and J1772 chargers?

Level 2 describes the charging speed and power level, while J1772 describes the connector type.

A Level 2 charger can use a J1772 connector, but the two terms are not interchangeable. J1772 chargers can operate at Level 1 or Level 2 depending on voltage and amperage.

What’s the difference between J1772 Level 1 and Level 2 charging?

The main difference is the electrical supply:

• J1772 Level 1: 120V power, slower charging, no special installation
• J1772 Level 2: 240V power, faster charging, requires installation

Level 2 J1772 charging is the most common choice for home EV charging upgrades.

How long does it take to charge an EV with a J1772 charger?

Charging time depends on the charger’s power output and the vehicle’s onboard charger.

As a general guideline:

• Level 1 J1772 charging may add 3–6 miles of range per hour
• Level 2 J1772 charging may add 20–40 miles of range per hour

How to install a J1772 EV charger at home?

Installing a home J1772 charger typically involves mounting the charger near your parking space and connecting it to a dedicated electrical circuit.

Level 2 J1772 chargers require a 240V supply and should be installed by a licensed electrician to ensure safety, permitting, and code compliance.

What are the best J1772 chargers for home use?

The best J1772 charger for home use depends on your driving needs and electrical capacity.

When comparing options, consider:

• Maximum amperage and charging speed
• Plug-in vs. hardwired installation
• Weather rating for indoor or outdoor use
• Warranty and manufacturer support
• Smart features such as scheduling or energy tracking

Where can I buy J1772 chargers?

J1772 chargers are available from online retailers, EV specialty stores, electrical supply distributors, and directly from manufacturers.

Always confirm product specifications and compatibility before purchasing.

Where can I buy a J1772 charger, and how much does it cost?

J1772 charger prices vary based on power output, features, and build quality.

Basic Level 1 units are typically the least expensive, while higher-powered Level 2 chargers with smart features are priced higher.

How much does a J1772 charger cost?

Charger hardware cost depends on charging level and features. Installation costs—if required—are separate and depend on your home’s electrical setup.

For accurate budgeting, consider both the charger price and installation expenses.

How does a J1772 charger compare to a CCS charger?

A J1772 charger is used for AC charging, while a CCS charger is used for DC fast charging.

J1772 charging is common for home and workplace use, whereas CCS chargers are typically found at public fast-charging locations.

Are J1772 chargers compatible with all EV charging stations?

J1772 chargers are widely compatible with AC charging stations that support the J1772 standard.

However, J1772 connectors cannot be used directly at DC fast charging stations unless the vehicle and station support AC charging at that location.
