Chinese website Chongdiantou tested various Apple power adapters with the iPhone 14 and iPhone 14 Pro Max, providing useful data on charging speeds and revealing which charger is most valuable for fast charging.


The short answer is to choose Apple’s 30W USB-C power adapter, which for $ 39 is the company’s cheapest charger that can charge an iPhone 14 and iPhone 14 Pro Max at maximum supported charging speeds of 25W and 27W respectively. Apple’s other more expensive chargers, such as the new $ 59 35W dual USB-C adapter, charge devices at a negligible speed at best.
