Another fast charger for iPhone XS and iPhone XS Max that you can buy is the Aukey 30W USB-C charger with USB Power Delivery and Quick Charge 3.0 support. This charger is definitely one of the best fast chargers for iPhone XS that you can get because not only does it charge the iPhone XS at a fast speed, it also has a second USB-A port with QC3.0 support so you can use the same adapter for other devices as well! It also looks cool in black, so there’s that.
