Both will work. By the way your ports are providing 5Watts from one port and about 10Watts from the other port. Your iPhone 6s will handle that with ease. NOTE that the iPhone will control the total electrical power it needs to charge the battery. It will not overcharge. The 5Watts port will charge slower than the 10Watts port that you have.
amperage
I have always been confused when it came to how much charge does a battery charge. Let''s say, a phone battery: It says 1900 mAh @3.7 v. Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?
How Much Power Does an Inverter Draw from a Battery? Current
When a device is connected to a battery, the load it exerts determines how much current and voltage the battery must supply. Higher loads result in increased power draw, which can deplete the battery faster. Discharge rate reflects how quickly a battery loses its charge. A high discharge rate results in rapid energy consumption. Lead-acid
