I strongly suggest buying a 20W adapter.
It changed my life when I bought my iPhone 12 and I'm not being sarcastic.
I would agree with this

Charging fast while also being able to transfer data quickly usually means the cable needs to be thicker. Fun fact: USB-C spec requires at least USB 2.0 transfer speed but most people seem to assume C = 3.0They can charge fast, but not transfer fast? So why design a USB 2.0 that can charge fadt when when there is 3.0? Asking for a friend.
(I think it’s 3.0 but they are limiting transfers to stop external storage use)
Totally agree. Bought the same charger today and it works very well. Looks great, charges 3 devices at a time and I was able to get it at BestBuy for $119 since they were marked wrong. Still pricey, but Belkin makes a good product.I use that Belkin 3-in-1 wireless charger with MagSafe... Best charger ever!
Don't limit your search to studies specific to iPhone batteries - it's well-established of all lithium-ion batteries. Lots of research papers and articles are behind academic paywalls, but here's one: https://www.frontiersin.org/articles/10.3389/fenrg.2022.905710/full which also includes a raft of references which cover the same area of research.
Chinese website Chongdiantou has tested a variety of Apple power adapters with the iPhone 14 and the iPhone 14 Pro Max, providing useful data about charging speeds and revealing which charger is the most valuable for fast charging.

The short answer is to choose Apple's 30W USB-C power adapter, which at $39 is the company's lowest-priced charger that can charge the iPhone 14 and iPhone 14 Pro Max at their maximum supported charging speeds of 25W and 27W, respectively. All other higher-priced Apple chargers, such as the new 35W adapter with dual USB-C ports for $59, charge the devices at equal to negligibly faster speeds at best.
The chart below is in Chinese, but it shows that all 29W or higher Apple adapters charged the iPhone 14 Pro Max at 26W to nearly 27W.

While charging speeds for the iPhone 14 Plus and iPhone 14 Pro remain to be seen, the 30W adapter should be the best choice for those devices too.
Interestingly, Chongdiantou found that the iPhone 14 Pro Max can briefly achieve peak charging speeds of nearly 29W with Apple's older 29W power adapter, which was designed for the 12-inch MacBook and discontinued in June 2018.
By comparison, the iPhone 13 and iPhone 13 Pro Max are capable of up to 23W and 27W charging speeds, respectively, according to Chongdiantou's sister website ChargerLAB, so Lightning charging speeds for all iPhone 14 models are largely the same this year ahead of Apple's expected switch to USB-C for iPhone 15 models next year.
Apple no longer includes a charger in the box with any iPhones. For all four iPhone 14 models, the company says users can charge the devices to 50% in around 30 to 35 minutes with a supported 20W or higher power adapter.
Update: Chongdiantou sister website ChargerLAB has shared a video of its iPhone 14 Pro Max charging speed test.

You don’t have to buy a new one. The old ones work just fine. That’s the power of USB.5W to 15W to 20W to 30W power adapters. Apple is surely saving the environment and charging back to every customer who buys these adapters separately even after spending $799 - $999+USD (or $1,099+ CDN) for their phones. Total insanity.![]()
I'm thinking less than that. I'd have to check tonight on my Wife's 13PMSo what wattage does the iPhone 14 Pro drop to after 50% charge? 20 watts?
Do you have a citation for those 25W and 27W claims?maximum supported charging speeds of 25W and 27W,
