As we all had experienced, most USB AC/DC phone chargers had a power rating of 5VDC 2.1A, and generally shared among the multiple USB port available.
ie. if you plug in a single unit to the multiple-port USB charger, it enjoyed the exclusive 2.1 Ampere, but once a secondary USB equipment is plugged in, the current will be shared. Lower the current, Longer the battery charging time.
I wonder if anyone had come across any multiple port charger, where the current is minimum 2.1A, stay constant regardless it is multiple or single port.
Any recommendation?
