Apple’s iPhone 15 Pro Max is capable of charging at a maximum speed of up to 30W and Apple offers a range of different chargers for its iPhones, these include a 5W charger, a 12W charger, a 20W ...

MagSafe chargers will recharge the iPhone 15 Pro Max at 15W. I use both wired and wireless charging with my iPhone 14 Pro, which also supports unofficial speeds of over 20W.

If you're buying or have already purchased the latest iPad model, it will use a USB-C charger. As for iPhones, the iPhone 15, 15 Plus, 15 Pro, and 15 Pro Max all use a USB-C for charging.

For example, the charger can charge an iPhone 14 Pro Max from 0 to 50% in just 30 minutes. It also meets the six-level energy efficiency standard, so it uses less energy than older chargers.

I ran several charging tests on the iPhone 15 Pro and Pro Max. I used a 20-watt charger for the first test and noted how the battery percentage increased after 30 minutes.
