I have an iPhone 5s using 9.3.5 and want to charge it using a power bank. The power bank I have has a choice of 2 outputs. Either 1 Amp or 2.1 Amp. Which one should I use and why please? I want to make sure I don't damage my phone battery. Thanks.
iPhone 5s, iOS 9.3.5
You can use either, the phone controls the amount of power it uses, not the other way around.
Thanks for this. What are the different outputs used for then?
Both ports will work but i suggest you use the 2.1 Amp. The 2.1 Amp port will allow your phone to charge faster than the 1 Amp.
Well, plugging a tablet into the 1 amp port would be an exercise in frustration. But, it doesn't make a whole lot of sense to me that the manufacture would bother setting it up that way. I have a mophie power pack with two USB ports. They are exactly the same. No suggestion that I should use one for one thing and the other for another.

And iPhone 5S will not charge any faster on a 2.1 Amp port than on a 1 Amp.

iPads require more wattage
I think the reason the two ports are different is if you use both at the same time you won't overload the powerpack. I have 3 power packs, all different. They all have a 1 amp port, a 2.2 amp port, and one of them also has a 500 ma port, and both (all 3 on the last) can be used at the same time (so I can charge my iPhone, my iPad, and my BT headset at the same time).
I'm looking at the box for a mophie XL which is what I have. It has two 2.1 ports. I've never been told not to charge two iPads at the same time but nor have I tried to do so.
Just as Csound1 has answered, the iPhone won't get damaged from either of the ports. A smartphone is built in with a protocol of how much Amperage it should accept from a charger so it doesn't get damaged.
charge iPhone 5s from power bank
