Apple canceled its wireless charging product, AirPower, on Friday, saying in a statement that it was unable to meet its own standards for design and manufacturing.

Announced in September 2017 at an Apple iPhone event, AirPower was supposed to be a charging mat on which users could place and wirelessly charge their iPhones, Apple Watches, and AirPods charging cases. During a “sneak peek” at that 2017 event, Apple’s senior vice president of global marketing, Phil Schiller, said that customers could expect the product in 2018.

“After much effort, we’ve concluded AirPower will not achieve our high standards and we have cancelled the project,” Dan Riccio, Apple’s senior vice president of hardware engineering, said in a statement Friday. “We apologize to those customers who were looking forward to this launch.”
