You can safely and quickly charge your iPhone with an Apple iPhone 13, 12, 11, X, SE (2020), or 8 charger. These iPhones all support extra fast charging via Power Deliver. Witch such an iPhone fast charger, you can charge your empty battery for 50% in half an hour. Without fast charging, you'll reach 30% in the same time. Every Power Delivery charger with at least 20W power is a suitable iPhone fast charger. It doesn't matter if you choose a charger from Apple or another brand. Many iPhones, including the iPhone 12, don't come with a charger, but with a USB-C to Lightning cable. These cables only fit USB-C chargers, not USB-A chargers.
