It’s also worth keeping in mind that, just like fast charging at lower speeds, you’re not going to get the full 27 watts for the entire charging cycle.

Get the Charger HereĬhargerLAB told MacRumors that the iPhone 13 Pro does max out at 23W, so it’s slightly better than last year’s iPhone 12 models, but that’s not a significant enough boost to really care about. Notably, these faster charging speeds are only available on the iPhone 13 Pro Max. Plus, the standard USB-C adapter that Apple sold for the iPhone 12 was only rated as 20W to begin with, which was already an increase over the 18W adapter that came bundled with the iPhone 11 Pro and iPhone 11 Pro Max back in 2019. Technically speaking, the iPhone 12 could get slightly faster with an appropriate charger, clocking in at around 21-22W, but that’s a negligible difference in practical terms. This is an increase over its predecessor, the iPhone 12 Pro Max, which charged at the more Apple-standard 20W speeds.
