Apple has tested the iPhones on all their adapters up to 140-watts with no issues, as has Consumer Reports and others. The iPhone uses only the power it needs - up to 20 watts for regular iPhones, max 27 watts for Pros, and max 29 ways for Pro Maxes. Same with Apple certified adapters and cables. So maximum supported and tested adapter is 140-watt Apple adapter. Answer from Richard1864 on reddit.com

It’s maximum 20w. Any charger above that won’t charge any faster.

Is it true that using a charger rated above iPhone maximum wattage can “magically” double your charging speed?
No magic here—using a charger with higher wattage than your iPhone’s designed limit won’t double charging speed. The phone controls how much power it accepts to protect the battery, so more wattage just means the charger can supply more if needed, not that the phone will take it. Charging speed is a balance, not a wattage contest. Wandkey.

Will using a 30W charger harm the iPhone 14 Pro Max's battery?
No, using a 30W charger will not harm the iPhone 14 Pro Max’s battery because the phone controls how much power it draws to protect battery health. Higher wattage chargers simply provide the capacity to deliver more power, but the iPhone only takes what it needs. This helps prevent overheating or damage caused by too much power. Wandkey.

Is a 30W charger significantly faster than a 20W charger for the iPhone 14 Pro Max?
While a 30W charger can provide more power, the iPhone 14 Pro Max is designed to draw a maximum charging speed close to what a 20W charger offers. This means using a 30W charger may not result in a noticeably faster charge compared to a 20W charger, as the phone’s internal charging limits take priority. For typical usage, 20W is sufficient and efficient for fast charging. Apple Community.
