USB-C to USB-C Cable 2-Pack vs IP68 Waterproof Phone Case, Underwater Snorkeling Case, Inflated Touchscreen for Diving: 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 Casebus.
• We flag Elastomer membrane degradation and leaching under UV/heat, Microplastics from case wear or membrane fragmentation and Bacterial or mold growth inside sealed case on the Casebus and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Casebus is Plastic case with waterproof membrane, 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 Casebus grade, at 35% confidence against 78%, because it discloses less.
