The reason for using higher voltage is because you need thicker wiring to handle higher currents, and you get loss through resistance and heat. So with a 5v only charger the MM probably will draw only 2A max, which is only 10W. The 18w charger can deliver, and the MM accept [email protected] Many found MM charges even faster with a higher wattage QC.
