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 Plastic housing leachables (BPA, phthalates), Water-resistant coating (PFAS risk), Lithium battery thermal runaway and electrolyte leakage and Contact dermatitis from coating or grip material on the Mophie and not on the Mophie.
- The Mophie is Lithium-ion battery, plastic housing, metal contacts where the Mophie is Plastic housing, lithium battery, rubber grip, unspecified water-resistant coating, 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 →
