Amazon Essentials Case-Mate Waterproof 2L Dry Bag With Built-In Phone Pouch Phone Pouch With Strap vs USB-C to USB-C Cable 2-Pack: which is safer?

Where these two actually differ

• We flag Microplastics from degradation and Bacterial or mold growth in sealed compartment on the Case-Mate and not on the Anker.
• 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 Case-Mate.
• The Case-Mate is Vinyl/PVC where the Anker is PVC outer jacket, copper conductors, standard connectors, 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 Case-Mate grade, at 45% confidence against 78%, because it discloses less.
