How do you calculate the power of a charger?
Charging power is based on three things: power (P, measured in Watts), current (I, measured in amps or milliamps), and voltage (V, measured in volts). The amount of power is determined by the equation P = IV. In other words, power is the product of current multiplied by voltage.
How many watts does a lithium battery charger use?
Lithium battery cell voltage, which is 3.6V or 3.7V, is most likely to be determined in these cases. This would be its effective Watt-hour efficiency by time 3.6 (or 3.7), then divided by 1000. For instance, the actual capacity of a 10,000mAh battery is 10000x 3.6/1000= 36 Watt-hour.
