Yes Power in watts is equal to the voltage applied multiplied by the current drawn. Power remains constant less any losses due to inefficiencies of the converter. roughly power in = power out. or in another way to figure out the current draw would be to take that 2000 watts and divide it by the 12 volts and come up with 166.6 amps at 12 volts No free ride by using 12volts, otherwise I'd run my entire house on 12 volts.
