Where these two actually differ

  • We flag Lithium-ion battery thermal runaway risk, Electromagnetic field exposure and Counterfeit or degraded battery cell defects on the Mophie and not on the Mophie.
  • We flag Undisclosed coating composition and potential PFAS presence, Microplastic shedding from coating degradation, Volatile organic compound (VOC) off-gassing from polymer base and coatings and Bacterial or mold growth in seal crevices on the Mophie and not on the Mophie.
  • The Mophie is Lithium-ion battery, plastic housing, metal contacts where the Mophie is Polymer case with unspecified waterproof/protective coatings, which is most of the difference in these two grades.
  • The gap is 45 points, wide enough that this is not a close call, and the Mophie is the one to buy.
  • We are less certain about the Mophie grade, at 35% confidence against 65%, because it discloses less.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
