The iPhone XS Max doesn't come with a fast charger in the box

this is by design.

charging your brand new, $1100+ iPhone XS Max with a regular charger, rather than a fast charger, builds up a sense of anticipation with the phone.

imagine if the phone charged quickly as soon as you bought it, you'd be bored with the phone because it's so frequently accessible. but with the regular charger, your excitement builds for the iPhone XS Max to unprecedented levels.

Apple compares this concept to ordering a meal at a Michelin Star rated restaurant in Paris. You don't complain that the food is taking too long to cook, you wait patiently for each course because it's worth it.

basically you spend an extra $18 for the fastest fast charger.

To get fast charging on iPhone X, iPhone 8, and iPhone 8 Plus, you don't need anything over 18W, and you don't need a USB-C power adapter that's from Apple. The third-party options work just as well, but you will probably want to pick up Apple's USB-C to Lightning cable over the alternatives.

i doubt the xs max can take more than 18w.

the idea that you have to spend $70 on a macbook usb-c brick to get fast charging is disingenuous.
