Not just any charge cable DuraTek cables were forged from superior quality materials for ultimate durability. Kevlar fibers reinforce the inner wiring for added strength abrasion-resistant nylon forms a tough outer jacket and highly flexible insulation minimizes damage from friction. The strength created by these resilient ingredients is further enhanced by smart design details to reinforce the cable at its stress points. This ensures the finished product can withstand even the most demanding routines and perform above and beyond expectation to deliver a cable that borders on indestructible.
