Can I use the 40W or 100W charger for my iPhone 📱 13 pro max?

You can fast charge your iPhone 8 and later up to 50 percent battery in around 30 minutes.1

Fast charging works when you use an Apple USB-C to Lightning cable and one of these adapters:

• Apple 18W, 20W,2 29W, 30W, 35W, 61W, 67W, 87W, or 96W, or 140W USB-C Power Adapter
• A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

If you're not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter:
