    an ammeter is a function of the multimeter. To get an accurate measure of wattage, u need a watt meter but they are generally expensive. Like mentioned before, you can get the amperage and use the formula:
    P=VxI
    p=power v=voltage i=current

    you may have also heard it called the "west virginia" equation: W=VA
    watts = volts * amps
