While the charging speeds of the iPhone 14 Plus and iPhone 14 Pro are still to be seen, a 30W adapter should be the best option for those devices as well.

Interestingly, ZhongDiantou He found that the iPhone 14 Pro Max could briefly achieve peak charging speeds of around 29W with Apple’s older 29W power adapter, which was designed for the 12-inch MacBook and was discontinued in June 2018.

In comparison, the iPhone 13 and iPhone 13 Pro Max are Capable of charging speeds of up to 23W and 27Wrespectively, according to ZhongDiantouSister site Charger LabSo the Lightning charging speeds for all iPhone 14 models are pretty much the same this year ahead of Apple’s expected switch to USB-C for next year’s iPhone 15 models.
