Find out what you need to fast charge your iPhone.
What you need
You can fast charge your iPhone 8 or later up to 50 per cent battery in around 30 minutes. Find testing information for various iPhone models.
To fast charge, you need an iPhone 15 model with a USB-C cable like the one that came in the box, or an earlier
iPhone model with a USB-C to Lightning cable and one of these adapters:
- Apple 18W, 20W, 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)
Fast charging might not work in conditions that are too cold or too hot.
If you're not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter:
