A610 Universal Waterproof Float Case vs EV603BT Car Charger: which is safer?

Where these two actually differ

• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Spigen.
• We flag Plastic housing leaching (thermal stress), Metal contact corrosion and degradation and Electrical safety and short-circuit risk on the Spigen and not on the Spigen.
• The Spigen is TPE (thermoplastic elastomer) with waterproof sealing where the Spigen is Plastic housing, metal contacts, standard automotive charger components, 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.
