Built with quadruple bulletproof fiber cores to withstand up to 25,000 bends, this material is both stronger and slimmer. The most recent generation of PowerLine is even thinner than its predecessors without sacrificing strength thanks to an improved internal structure. Power Delivery Compatible: When using PowerLine III in conjunction with an 18W Power Delivery charger, you can charge a Samsung device up to 50% in just 30 minutes. (Charger not included.) Increased Grip: The cable's textured grooves on the head improve grip, making plugging and pulling simpler.
