Can I use 3A cable in 5V 2A charger?
3A cable simply it means the cable can withstand if current draw at 3A (theory measure) if the current draw goes over than 3A it will get heated up and burnt (damage). Therefore 3A cable simply good for 2A/5, 1A/10, and 3A/3v all perfectly fit in the current draw.
