I can either get an 18.5v 4.9A, or a 19v 6.3A laptop car cord power supply. The one that came with it is 18.5v 6A. Which would you recommend(same price $25)? So, I cut the Mac power cord, put a 3 wire connector on both ends, connect power from power supply, and the isense wire goes to ground through a 2.2-3.3k resistor, correct? Any other advice? Power usage difference? Would the larger one be less likely to overheat?
