Hi. I thought of buying Nitecore universal charger. I noticed it has 5V 2A and 9V 2A specified inder input. The charger comes with USB cable but without wall plug.
I have USB plug with 5V 2A port and 5V 1A port. I have USB plug that cane with my Sony bluetooth speaker. It has 5V 1.5A port. I also have older USB plug with 5V 1A. None of them has 9V 2A. I wonder what is 9V 2A is used for then and do I need to buy USB plug from thenlm that can supply 9V 2A.
