A 30-amp Level 2 EV charger typically delivers around 6.6 kW to 7.2 kW of power. This translates to adding 18-22 miles of range per hour of charging for a typical passenger car battery. The exact kW output can vary slightly depending on charger efficiency and minor fluctuations in your home's voltage. However, this range provides a good estimate of the practical charging speed of these chargers.
