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.

Interesting, I wish they had tested the regular 14 Pro charging speeds. So far I haven’t noticed mine charging really fast, it even seems to be a bit slower than my s20+ which maxes out at 25W

Gotta be in it to win it
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. :(
Whether or not a brick was included if someone wanted a faster charger they would buy it. That’s 2 bricks instead of one.

I just use my Macbook Air M1 charger for everything so I'm all good

Apart from the fact I keep forgetting to swap the USB-C to USB-C cable when it comes to wanting to charge my iPhone!

The headline should read:
Macrumors yet again struggles to read a website in an effort to generate a clickbait article

14 Pro Max charging as listed on Apple’s site:
Fast-charge capableUp to 50% charge in 35 minutes with 20W adapter or higher (available separately)

Article states differently.

You're welcome.

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? 😞😞
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.

The apple store sold me a 20W charger for my 14 Pro Max. Hopefully that will work ok.

I use an Anker 40W charger so I am always getting the max speed supported, unless optimized charging is doing its thing, but that’s a whole different matter
I am LOVING the battery on the 14 Pro Max!! It is crazy how long I was able to actively use the phone all day without needing to charge. That’s also with all these new features like promotion that I wasn’t already used to, which presumably take more power. And background processes likely have been indexing stuff on the new phone too.
