Quick answers
Is it safe to charge the iPhone 18 Pro Max with the Apple 30W USB-C?
Yes. USB Power Delivery negotiates power, so the iPhone 18 Pro Max only takes what it can handle and the charger only gives what it can supply. A weaker charger is slower, not dangerous.
How many watts does the iPhone 18 Pro Max need for fast charging?
60 W or more, from a USB-C PD charger that supports AVS. Fast charges to 50% in about 15 minutes with a 60W-capable USB-C adapter that supports Adjustable Voltage Supply (AVS), such as Apple’s 40W Dynamic Power Adapter (60W Max). Without AVS, reports show it settles at roughly 27–30W.
How long does the iPhone 18 Pro Max take to charge with the Apple 30W USB-C?
About 21 min to 50% and 59 min to full, estimated with the device idle.
