Where these two actually differ
- We flag Copper conductor corrosion and oxidation, Thermal degradation of PVC jacket and Microplastic shedding from jacket wear on the Anker and not on the Tech21.
- We flag Microplastic shedding from TPR jacket degradation and Copper leaching from exposed core on the Tech21 and not on the Anker.
- The Anker is PVC outer jacket, copper conductors, standard connectors where the Tech21 is Thermoplastic rubber (TPR) overmold, copper core, 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 →
