Definitely. I am addicted using the large iPad chargers for iPhones. Is this wrong? I am under the imagination that they are far superior, i.e. charge faster!
Fast charging is typically extremely hard on the battery, so I’m the opposite to you - I actively try to use the lowest wattage charger whenever I can (5W).
My understanding, borne out by experience, is that this is far, far kinder to the battery and will significantly increase the lifespan of the battery (in combination with good battery charging and discharging practice).
I have one or two high output chargers for when I need my devices charged in a hurry, but that’s extremely uncommon.
My main phone, an iPhone X bought at launch (Nov 2017), is still at 89% battery health and working well.
