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.
Despite being more than two years old, Apple's AirPods Pro 2 still dominate the premium wireless‑earbud space, thanks to a potent mix of top‑tier audio, class‑leading noise cancellation, and Apple's habit of delivering major new features through software updates.

Apple's iPhone development roadmap runs several years into the future and the company is continually working with suppliers on several successive iPhone models simultaneously, which is why we often get rumored features months ahead of launch. The iPhone 17 series is no different, and we already have a good idea of what to expect from Apple's 2025 smartphone lineup.

Apple is preparing a "bold" new iPhone Pro model for the iPhone's 20th anniversary in 2027, according to Bloomberg's Mark Gurman. As part of what's being described as a "major shake-up," Apple is said to be developing a design that makes more extensive use of glass – and this could point directly to the display itself.
Here's the case for Apple releasing a truly all-screen iPhone with no...

The first iOS 19 beta is less than two months away, and there are already a handful of new features that are expected with the update.
Apple should release the first iOS 19 beta to developers immediately following the WWDC 2025 keynote, which is scheduled for Monday, June 9. Following beta testing, the update should be released to the general public in September.
Below, we recap the key...
I'm using a 5W wired charger for my overnight charge. I do have a MagSafe charger connected to a 20W power brick but only using that if I need a quick charge during daytime
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. :(
That’s very informative and interesting. Is it weird that I continue to use original 5W Apple’s charging adapter to charge my new iPhone 14 Pro Max? ??

Same here.No point in fast charging when you are doing it overnight.

No, its not weird. The trend is faster is better but the 5w charger will have the least impact on the battery long term and is sufficient for charging overnight, which is how most people charge their phones, supposedly.
Not mentioned is for how long these peak charging rates are maintained. If only for 5 minutes, it is pretty worthless. The following graph is more useful, which shows, for example, time to reach 80% charge, which is not much different between 20W and 30W chargers The original article states the 20W charger charges 79% in 1 hour, and the 30W charger charges 82% in 1 hour. I suppose it depends on how important 3% is to you, whether it is worth twice the cost and larger size charger. 100% charge time is only 2 minutes different.
btw, this graph is for iPhone 13, but they rationalize that iPhone 14 is (probably?) the same.
Charging as fast as possible may not be the best thing for battery longevity, too.
