Marketed using Apple’s own images, the knock-offs provide few guarantees as to exactly what customers will get. Reiko calls its version “Data Cable for Apple Watch” even though the magnetic cables are used solely for charging, not for data. They all tout 100cm (1-meter) lengths comparable to Apple’s $29 cables and typically use pictures of the metal-clad Apple Watch Magnetic Charging Cable, but some of the postings additionally include shots of the all-plastic cable shipped with the Apple Watch Sport. All of the listings promise that the cable is “high temperature resistant,” with “shock absorption and good air permeability,” for whatever that’s worth.
