is charging 5V1A or 5V/2.1A
I have an external battery and need to know which output to use to charge my iphone 5s, 5V/1A or 5V/2.1A - also which works for iPad
Aperture 3, OS X Mountain Lion (10.8.5)
Both ports will work with either device.
The iPhone will use max of 1A. Plug it into the 2.1A and it will use only 1A.
The iPad will use max of 2.1A. Plug it into the 1A port and it will use only 1A. (since that is the max available)
Plug it into the 2.1A output and it will use 2.1A and charge faster.
