Can i use my fast charger with another phones?

[AC Question]

Is It damaging the others phones or the charger ?

No. They won't damage the other phone, but they won't fast charge the other phone either. There'd be no difference from a normal charger. The fast charger works because of the phone and charger combination, not just the charger. Both the phone and charger must br fast charge capable.
