If it takes 1 amp at 120 volts it will consume 12 amps at 12 volts not figuring any loss in the converting. If your PW is 12v you can charge it as you drive also. Just figure out what the fan needs and times it by 10. The battry will put out a fair amount of amps for 3 hours and 2 regular 50-watt head lights use around 9 amps at 12 volts same as .9 amps @120 volts(approx). Mark H.
