Using “old” 5W iPhone 5 Power adapter to charge a new iPhone XR I would like to know if it is safe to use an “old” 5W Power Adapter (charging brick) from an iPhone 5 to charge my new iPhone XR. I am specifically referring to the original (and, of course, genuine) charging brick that my old iPhone 5 included in the box.

Yeah, I know that my new iPhone XR already includes a cable and a 5W Power Adapter. However, I would like to have two chargers (one at my work and the other one at home).

I would definitely need to purchase a new lightning cable, but, my question is, Is it necessary to purchase a new charging brick? Could the “old” charging brick damage my new phone (since it is too old)? It seems to work fine. It worked perfectly with my iPhone 5, but I am not sure if I should use it on my iPhone XR.

Yes.

No.

No. As it is working fine with an iPhone 5, it will be fine to use it with iPhone XR.



So, yes, it will be fine using the old power adapter from your iPhone 5 to charge your iPhone XR.
