Where these two actually differ
- We flag Lithium-ion thermal runaway (overcharge/short circuit) on the Belkin and not on the Samsung.
- We flag Electrical/thermal safety (design integrity) and Manufacturing contamination or counterfeit units on the Samsung and not on the Belkin.
- The Belkin is lithium-ion battery, plastic housing, circuit board where the Samsung is plastic housing, internal circuits, ceramic capacitors, 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, 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 →
