Level 1 charging uses a standard 120-volt household electrical outlet. It is the slowest charging option and typically provides around 2 to 5 miles of range per hour of charging, depending on the vehicle.
Level 2 charging utilizes a 240-volt power source, similar to what is used for large appliances like clothes dryers or electric stoves. Level 2 chargers can provide significantly faster charging than Level 1, typically delivering between 10 to 30 miles of range per hour of charging.
DC Fast Charging, also known as Level 3 charging, is the fastest charging option available for EVs. These chargers use direct current (DC) power and can provide high-power charging, allowing EVs to recharge to 80% capacity in as little as 20 to 30 minutes.
