USB-C to USB-C Cable 2-Pack vs Gobi XL Dry Phone Case: 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 Akona.
• We flag Polymer degradation over time, Volatile organic compound (VOC) off-gassing, Microorganism or bacterial growth inside sealed environment and Closure seal integrity loss on the Akona and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Akona is Proprietary polymer dry bag, 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.
• We are less certain about the Akona grade, at 45% confidence against 78%, because it discloses less.
