Most Level 2 chargers deliver a charging range from 6.2 to 19.2 kilowatts, averaging around 7.6 kilowatts. This would provide between 18 and 25 miles of charge per hour and take approximately 8 hours to charge a battery electric vehicle (BEV) fully. Level 1 chargers have much lower power ratings. Supplying an average of 1.3 to 2.4 kilowatts, Level 1 chargers plug into a standard 120-volt AC outlet and provide 3 to 5 miles of EV range per hour.
