Quick answers
Is it safe to charge the iPhone 18 Pro Max with the Apple 5W USB-A?
Yes, but it is a basic 5V USB-A charger without Power Delivery, so it can only deliver a few watts.
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 5W USB-A?
About 1 h to 50% and 2 h 20 min to full, estimated with the device idle.
