Watts is like foam on a mug of beer
it really ain’t beer..
just as Watts ain’t what’s powering your engines…it’s the Amperage
test your engines to see what Amperage they draw under strain…connect a Multimeter set to Amperage in series…hold your engine from moving…apply power…see how much current it draws
