So, I know the basic equation of W=V*A, but how would I physically do this in a circuit? Say I have 90W=19V*4.74A (http://www.chargerbuy.com/replaceme...9DD87xaDL8SQcvxNtWCeo_2nl68GmdozOoxoCbW3w_wcB) for reference. In the project that I am undertaking I need to get as many Amps out of this as possible. Theoretically, I could get 90A out of this but I know it's highly unlikely. If there's at least a way to get 40A out of this circuit I would greatly appreciate knowing how to do so. I plan on cutting the proprietary plug and wring to the +/- leads. If you need any other info just reply, thanks.
