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 BPA or phthalates in plastic housing, Polymer degradation and leachate release and Battery leakage and chemical exposure risk on the Mophie and not on the Mophie.
- The Mophie is Lithium-ion battery, plastic housing, metal contacts where the Mophie is Plastic housing, synthetic polymer battery casing, 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 Mophie grade, at 35% confidence against 65%, because it discloses less.
