Is there any problem on using a fast charger to charge my iPhone 6s?

I would like to know if using a bigger charger (ex iPad charger) can damage smaller battery of iPhone (ex iPhone 6s).

iPhone 6s, iOS 13

No problem, provided you use a genuine Apple cable and a certified USB source between 1 and 2.5 amps, and any apple USB adapter, automobile or laptop USB will be OK.

The iphone will regulate the charge current, but a rogue foreign USB source with too high a voltage can cause overheating.
