18V motor running of a 19V laptop charger Answered
I do not understand how people can do this.
I have wired an 18V portable motor directly to a 19V 3.16A laptop power adapter and the motor kicks and kicks constantly but does not spin. The power adapter has more than 19V tested with a multimeter.
I did see reports that power adapters for laptops have a controller built into them to do some kind of regulating and thought this might be a problem and this motor has spun ok at times.
What could the problem be?
