USB-C to USB-C Cable 2-Pack vs USB-C PD 30W GaN Charger: which is safer?

Where these two actually differ

• We flag Copper conductor corrosion and oxidation, Thermal degradation of PVC jacket and Microplastic shedding from jacket wear on the Anker and not on the Mophie.
• We flag Metal contact corrosion and electrical safety and Thermal runaway or overheating on the Mophie and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Mophie is Plastic housing, metal contacts, silicon components, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
