Power Cord for Xtreme 2 Waterproof vs A610 Universal Waterproof Float Case: which is safer?

Where these two actually differ

• We flag Electrical shock risk from insulation degradation, Phthalates in PVC insulation, Thermal runaway if cord is pinched or compressed and Counterfeit or substandard replacement risk on the JBL and not on the Spigen.
• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the JBL.
• The JBL is Rubber/PVC power cord, standard electrical insulation 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 72%, because it discloses less.
