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 Polymer off-gassing (VOC release), Coating integrity and microleaching and Microplastic shedding over time on the Pelican and not on the Mophie.
- The Mophie is Lithium-ion battery, plastic housing, metal contacts where the Pelican is Proprietary thermoplastic polymer with unspecified coatings, which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the Mophie is the one to buy.
- We are less certain about the Pelican grade, at 25% 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 →
