For a pure EV, a Level 2 charger cuts the time it takes to replenish the battery from more than 18 hours with a 110-volt wall plug to as little as 3 hours.
All level 2 chargers require a 240 volt power source. However, not all of them are capable of transferring the same amount of energy to your electric vehicle. Some are rated for 3.6 kilowatt hours (kWhw) while others are rated for 7.2 kWh.
