7.5 W wireless charging

Well, in iOS 13.1 Apple disabled 7.5 W charging for virtually all chargers, including Anker’s. Than in iOS 13.3 it was re-enabled for SOME chargers, nobody knows which ones. So what’s going on? Listings for Anker’s chargers in different stores and on this site offer conflicting information and it seems the company doesn’t care clean that mess. Can anybody (Anker’s rep, preferably with actual knowledge) to tell what company’s chargers support 7.5 W charging with the latest iOS? In particularly, I’m interested in A2573 model.
