Stupid simple is what i called it .
And i also grouped my wires together , no led , no resistor , and no bananna plugs .
My cost was also zero dollars .
And more amperage than you could possible every need to feed your charger .
Hey on the red and black lead for the resistor , use the fan for the prosessor to draw the current and have and extra fan for cooling your battery ,s or favorite beverage .
You should have had a fan , on the mother board cooling the prosessor .
