Funnily enough, Apple does make an iPhone XS and iPhone XS Max fast charger. However, the company sells it separately rather than include it with the phone. This 30W fast charger is not available offline officially, and while you can get it from Amazon India, it’s priced at a ridiculous Rs. 12,941 there. So don’t do that.

I called up a bunch of Apple Authorised Reseller stores and confirmed that the 30W adapter is available with them for Rs. 4,500, so I’d suggest you buy it offline from one of the resellers.
