Where these two actually differ
- We flag Lithium-ion battery thermal and electrical hazard, Seal degradation and water ingress and Volatile organic compound (VOC) off-gassing from plastic and adhesives on the Mophie and not on the Pela.
- We flag Coating degradation and durability over time and Allergic contact dermatitis from plant fiber or resin on the Pela and not on the Mophie.
- The Mophie is Lithium battery, plastic housing, elastomer seals where the Pela is Flax fiber and plant-based resin blend, compostable, which is most of the difference in these two grades.
- We are less certain about the Mophie grade, at 35% confidence against 92%, because it discloses less.
Both products run through the same public rubric, which covers 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 →
