Other Can you use the 20w power brick to charge older iPhones?

[Macadelic]

I understand that the older phones will not take advantage of the faster charging, but I’m curious whether you can still use them to charge older iPhones. I assume it won’t damage them.

 

[BrettDS]

Yes, it’s not a problem

 

[seezar]

Yep, you can.

 

[now i see it]

Yes. Bigger power supplies won't harm the battery and they also won't charge it much faster.

The phone draws in the power needed and not pushed to the phone from the brick so no worries.
