It depends on the voltage.
Amps times volts equal watts

To calculate the watts from amps, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. So, without knowing the voltage in the circuit, it is not possible to accurately determine the wattage from just knowing the amperage.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
it would depend upon the current. Power (watts) = I (current in amps) x E (voltage). 2 watts = 15 amps x .133 volts 2 watts = 20 amps x .10 volt
Your 12 volt 2 amp battery charger draws 24 watts of power (12 volts x 2 amps = 24 watts).
41.666 amps. Divide watts by volts.
1000 watts at 9.5AMPS in 120 volt = 4.7 AMPS in 240 volt ..........Divide that by 2 according to the choice of voltage... 500 watts (120V) + 4.7Amp
