> In the US, the most powerful car chargers deliver a modest fraction of those megawatt outputs. All but the newest Tesla Superchargers top out at 250 kW and 400 V; in the 800 V world, Electrify America maxes out at 350 KW, IONNA’s new machines are rated for 400 kW, and ChargePoint has a 600 kW charger on the market. Those are the maximum speeds for those networks. Many deployed chargers are significantly lower than that - some even level 2, which is around 10-15 kW, which will take 8 hours or so to charge to max.
