Does anker 30-watt nano 3 charger reduce iPhone 14 pro max battery health?

Hi, I want to know if the Ankers nano 3 (30-watt) charger is harmful to iPhone 14 pro max battery health. or is any 30-watt fast charger bad for iPhone 14 pro max battery health? I have heard that a 30-watt charger will drain battery health faster. Is this true?
