An induction charger of a rechargeable shaver.
The voltage of charger automatically adjusts between 100 and 240Volt. Hertz is 50-60, amperage is 0.09A(90mA).
If the voltage in my city is 220Volt, how to deduce the wattage and amperage from the above data?
I can't apply the formula: wattage = voltage x amperage, because amperage of charger may vary as voltage of charger does. |
