Charging My iPhone 12 is not compatible with my Ranger. It took a lot energy via lightning to usb. Went there with explanation for proper product. Staff was unmotivated to assist me through texting communication. It s viable to do because I m Deaf. His eyes looking behind me at the entrance for incoming customers and suggested me to go to Best Buy via voice to text on his phone. That s the FIRST time a Apple store referring me to other place. Higuera Street? How sad....
