Using a 20W charger is sufficient for an iPhone 16 Pro, but a 30W or 45W charger can provide faster charging, especially if you're using demanding apps while charging. Answer from SimpleSammy21 on reddit.com

r/iphone on Reddit: Best charging block?
October 8, 2024 -

What’s the most optimal wattage for a charger for an iPhone 16 Pro? I’ve heard 45W is the max, but is that really the best? I’d be using some high quality 240w Anker cables. Is there really an appreciable difference in charging speed between a 20w and a 45w?

Discussions

Why do the apple charging blocks have a green dot?

The original ones without green dots were faulty and could be dangerous. So the green dot means it's safe.

5W USB-C charger block
Is a USB-A charger and USB-A to USB-C cable not an option? I really wouldn’t worry about it anyway. The part of charging that’s bad for your battery is the heat generated to “push” past 80 through 100, so the iPhone automatically switches to 5 watts for that last bit. More on reddit.com
