Use an amprobe on the power cord. to see what current it draws. Use a voltmeter to see how much voltage the power cord carries. Multiply the amps times the voltage. You could just open it up and look at the battery and go by the current and voltage it supplies.

not enough to worry about I guess, measure how much current its useing while running?
