The answer to 'which is better Level 2 EV charger or Level 1 EV charger' is that a Level 2 EV charger is generally better for most homeowners. Level 2 chargers provide faster charging speeds, typically 10-20 miles of range per hour of charging, compared to only 3-5 miles per hour for a Level 1 charger. This makes Level 2 chargers more convenient and efficient for daily driving needs.
However, Level 1 chargers are less expensive to install and can be a good option for homeowners who only occasionally need to charge their electric vehicle at home. They also don't require any special electrical work, making them a simpler DIY installation. The best choice depends on your specific driving needs and home setup.
