The answer to 'difference between EV charger' is that there are two main types of EV chargers for home use: Level 1 and Level 2. Level 1 chargers plug into a standard 120V household outlet and provide a slow, steady charge, adding around 3-5 miles of range per hour of charging. Level 2 chargers require a 240V outlet like those used for electric dryers and provide a faster charge, adding 10-20 miles of range per hour.
The main differences are in the charging speed, installation, and cost. Level 1 chargers are less expensive and easier to set up, but take much longer to fully charge an EV. Level 2 chargers are more expensive to purchase and install, but can significantly reduce charging time. The best choice depends on factors like your driving needs, garage space, and electrical system.
