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 Pelican.
  • We flag Polycarbonate thermal degradation and leaching, Rubber grip degradation and allergens, Microplastic shedding from wear and Bisphenol A (BPA) residue or leaching on the Pelican and not on the Mophie.
  • The Mophie is Lithium-ion battery, plastic housing, metal contacts where the Pelican is Polycarbonate shell, rubber grip, 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.

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 →
