What is More Important: Volts or Amps for Charging [Solved]
Amps: Measure the flow of electric current, how many electrons pass a point each second. Higher amperage can also result in faster charging times. Watts: This is the measurement of power output or the rate at which energy is transferred. To find the wattage of a charging device, like one with 240 volts and 30 amps, use this formula. Watts = 5 Volts x 2
