USB-C to USB-C Cable 2-Pack vs Nuxkst Premium USB Charger Charging Cable for Mophie Juice Pack Air Plus: 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 PVC thermal degradation and plasticizer migration on the Mophie and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Mophie is USB cable with standard PVC or TPE insulation, 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.
