USB-C to USB-C Cable 2-Pack vs [floatable] Floating Universal Ipx8 Waterproof Phone Case 2: 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 Cacoe.
• We flag Microplastic shedding or material degradation and Mold or bacterial growth in seals if water-sealed improperly on the Cacoe and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Cacoe is Waterproofed TPU/silicone case, 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 Cacoe grade, at 42% confidence against 78%, because it discloses less.
