New Nylon USB-C to USB-C 100W Cable (10 ft, 2-Pack) vs A610 Universal Waterproof Float Case: which is safer?

Where these two actually differ

• We flag Nylon jacket degradation under heat or UV, PVC or TPE insulation off-gassing at high power and Microplastic shedding from nylon jacket wear on the Anker and not on the Spigen.
• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Anker.
• The Anker is Nylon jacket with copper-alloy connectors where the Spigen is TPE (thermoplastic elastomer) with waterproof sealing, 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 Spigen grade, at 42% confidence against 78%, because it discloses less.
