What to know before buying

Listing details to confirm

Listing details conflict or remain unconfirmed: the title calls the design 0.5 inches thick, feature text says 14mm, and the detail dimensions say 0.1 inches thick. The title advertises 20W fast charging while feature text specifies 20W wired and 15W wireless, but the technical details list one port and do not confirm simultaneous charging. Verify the physical size, outputs, and intended configuration before buying.
