Why does 110 charge the car at 3mph, but 220 charge at 35mph? It’s 2x volts but >10x charge speed.
In: Physics
Charging speed depends on the voltage at the outlet AND the amps that the wiring can carry. Most charging equipment has safety measures, such as overheating protection, to make sure it doesn’t melt or catch fire. Using extension cords, especially with 110V chargers, will significantly slow down charging because of the added resistance.
