Failing to obtain sufficiently detailed information on the matter from Apple, a Chinese site carried out a regular comparison of the performance offered by the brand’s different chargers on the iPhone 14 and 14 Pro Max. The balance sheet might surprise you.
Chongdiantouthis is the name of the Chinese site which has been responsible for methodically comparing the capacities of fast charge offered by the main power supply units ofApple on the iPhone 14 et 14 Pro Max. Result of the races, the most powerful chargers (and the most expensive) are not faster than a modest 30 W block. Why? Because they’re just not supported to their full potential by the newer iPhones, which are limited to 25W and 27W fast charging respectively.
In detail, we discover that chargers over 29 W offer, from one model to another, an equivalent charging power, oscillating between 25.99 W for the large 140 W charger, to 26.55 W for the 87 W block. The 27 W maximum supported by the iPhone 14 Pro Max is therefore practically reached. Only the 18 and 20 W chargers come in at the bottom of the pack with much slower charging, stuck at 17.89 W and 19.57 W respectively.

30W charger is more than enough for newer iPhones
So remember that to charge your new iPhone 14 or 14 Pro Max, a 30 W charger (available at 45 euros from Apple) is perfectly sufficient to make the most of the capacities of the two devices when it comes to refueling. ‘energy. Apple, as a reminder, had announced that its iPhone 14s are capable of recovering 50% autonomy in 30 to 35 minutes on mains thanks to a 20W or higher charger. Charger that the brand has stopped supplying since the launch of the iPhone 12 and 12 Pro in 2020.
Chongdiantou, finally shares some other interesting findings with us. We learn, for example, that the iPhone 14 Pro Max is able to withstand a few peaks of charging at 29 W with the 29 W block, formerly supplied with the 12-inch MacBook – a model that Apple has stopped selling in 2018. Another observation of the site: the fast charging capacities of current iPhones equipped with Lightning sockets vary little from one year to another and from one model to another. It will therefore probably be necessary to wait the transition from iPhone 15 to USB-C connectivity to, perhaps, switch to a more copious fast charge.
