The main differences between a Level 2 charger and Level 3 fast charger is the amount of kWh the charger can provide and the plug types used to charge. A Level 3 fast charger can charge 10x – 50x faster than a Level 2 charger. Our Level 2 chargers use a J1772 plug whereas our Level 3 fast chargers can provide CCS, NACS, and CHAdeMO plugs.
